    - MaskedTextbox and allowing only valid int input I’m trying to setup a MaskedTextbox on a form to allow for only valid int input, but can’t seem to get something that I’m happy with. What I need is that the user enter something that’s entirely numeric (no decimals or negative signs), a minimum of 1 digit and a max of 4 digits. I’ve set the following properties: Mask=”0000”; ResetOnSpace=false; TextMaskFormat=MaskFormat.ExcludePromptAndLiterals;, and if you type in “323_”, or “_323”, its fine, and it doesn’t allow the user to press space. But, if you clear the field and type 3 (right cursor over) 23 to produce “3_23”, it obviously does not parse as a valid int. I then decided to try setting the maskedTextbox1.ValidationType = typeof(int); and setting up a typeValidationCompleted event, but unless the whole mask is completed (4 digits), it fails. How can I get this to work in my favor Its almost to the point that I just roll my own based on the standard textbox.

    - DataGridView Scrollbar Hi, I have a datagridview control on a form that contains lots of rows populated from an SQL database (done in code in a grid refresh subroutine). I have a timer control that updates the grid every 10 secs. The problem I have is that if I am in the process of scrolling down the grid and the timer event fires off a grid refresh, the grid resets the grid location and scrollbars. What I want to be able to do is set a flag on a mousedown event of the scrollbar and more importantly reset the flag on the mouseup event. This will enable the grid refresh routine to decide whether to refresh or not. However I don't seem to be able to do this as the events do not exist. The Scroll event allows me to set the flag to disable the refresh but I don't seem to be able to find a similar event to allow me to enable the refresh again. Can anyone help I am using VB2005.net Cheers Tag: Windows Forms General TreeView Comtrol: Add buttons to nodes in TreeView control Windows Forms

    - Parent, child forms check if open or closed Hi all, I'm new to c# and currently working on a project containing mdi forms. This is how the project is layed out. Parent form is called Street_Index. This contians a menu strip which can open 2 different forms. * Street_Search * Office_Search Within the Street_search form there is a button that i click that returns the results in another form called Search_Results. Search Results contains a grid and on double clicking the column of the grid it returns the results of that row back to Street_Search form which displays them in textboxes, grid, combobox, etc.. Within the Office_Search form there is also a button that opens the Search_Results form and then from there you can double click on the grid within Search_Results and open up Street_Search form which will display the results as previous. Now onto the question. What is the cleanest possible way to check to see if a childform is open or not and if it is refresh it or bring it into focus Thanks in advance Take care all.

    - datagridview - testing values of an unbound column Hi there. I have a datagridview that I populate via a table adapter and everything is working just fine. Now i'd like to give the user the option of: selecting multiple records in the grid by checking a checkbox. this checkbox is available for each row of data and i created it by adding an unbound column. What i'd like to do is enable a button on the same form only if one or more records have been selected by the user. how do i do this I was thinking about using the event: Private Sub DataGridView1_CellContentClick( ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick End Sub but this event can potentially be fired many times and for any column that's selected. Any suggestions Also, what's the easiest way to allow the user to edit the data for a given record I need to do another query when they request an edit because the current datagrid doesn't show all the details for the record. I intend to launch a new window to do this. Please and thanks. Tag: Windows Forms General TreeView Comtrol: Add buttons to nodes in TreeView control Windows Forms

    - how to host different controls in the same column in DataGridView control Hi, I am trying to create a datagridview. And in one column i want to have different type of cells (hosting different editing controls). For example, in the same column first cell shall host a combo box control, second cell shall host a text box control, third cell shall host DateTime picker control, another with Colorpicker control, etc. if i follow the host controls in windows forms Datagridview cell and c urrently if i change the cellTemplate property of DataGridViewColumn to calendarcell, then all the cells in that column become calendar cell. But instead i want to have a different control, for example colorpicker, in the next cell ie the one below this. Please advise how to achieve this using datagridview cell. -Madhu.

    - Removing multiple items in a ListView "at the same time" Hi all, Suppose we have 5 items in the ListView: "Alpha", "Bravo", "Charlie", "Delta" and "Echo". When we execute RemoveAt(0) followed by another RemoveAt(0), the first two items got removed. If we execute RemoveAt(0) followed by RemoveAt(1), "Alpha" and "Charlie" got removed. What I want to achieve is: I can multi-select items in the ListView to decide which items i'd like to delete. For example, I select "Alpha" and "Delta", so the index 0 and 3 are stored in SelectedIndexCollection. Then I enumerate this collection to delete these two in one run. At this time, if I run RemoveAt(0) first, the index of "Delta" will be changed to 2. Can I delete multiple items "at the same time" in the collection without having to mess with the indices Tag: Windows Forms General TreeView Comtrol: Add buttons to nodes in TreeView control Windows Forms

    - How to lock a control on a design form Hi there, I've created a design form at runtime using "System.ComponentModel.Design.DesignSurface" and cousins. I now want to lock individual controls on the form depending on conditions. I know I can do it this way: TypeDescriptor.GetProperties(myControl)["Locked"].SetValue(myControl, true); but this seems irregular. Is there a more mainstream way or is this it. Thanks.

    - Usefullness of any event Hi all, Visual Basic was released in the 1990's and immediately became hugely popular in corporate America because its new Event Driven design allowed programmers to deliver huge financial value to organizations. Event D riven is a key concept there, it seems to me. I have a theory today, as follows, for Windows Forms 2.0: THE VALUE OF AN EVENT TO A PROGRAMMER IS USUALLY INVERSELY RELATED TO THE NUMBER OF TIMES IT FIRES. For example, if, when a Form opens, its form_load event fires once and only once, that is a good thing for a programmer. But if it fires twice, then the event is not so useful. If it fires 6 or 7 or maybe 10 times every time the form is opened, then its value is even less. Thank goodness, in Windows Forms 2.0, the form_load event still fires once and only once. But next, take for example a ComboBox's SelectedIndexChanged Event. If, when we bind a form for example, the ComboBox's SelectedIndexChanged Event fires once, and only once, then it can be very valuable to a programmer. But if it fires twice, at unpredictable points, its value to a programmer is greatly diminished, it seems to me. And if it fires, 3 or 4, or maybe 7 or 8 times, unpredictably, its even more useless. Unfortunately, in Windows Forms 2.0, the SelectedIndexChanged fires multiple times, somewhat unpredictably to boot. Or take for example a simple button click. Hopefully, we programmers are confident that whatever code we put in a button's click event will only be processed once, and only once, when the user clicks the button. What if the button_click event fired not once, but 2 or 3, or maybe a dozen times, and not just when the user clicked, but during form_load and binding Would we want to use it This is only a theory of course. Can anybody see any weakness in this theory, or ways to state the theory more correctly Any thoughts or ideas will be appreciated.

    - Record Locking and Transactions in Strongly Typed Datasets Hi, I have a form with 4 tables displayed in different tabs, all coming from the same dataset. Here's part of the Form.Load event so you know what I mean: Code Snippet Me.taPaymentsApplied.Fill(Me.DsPaymentProcessing.PAYMENT_APPLIED) Me.taNewPayment.Fill(Me.DsPaymentProcessing.PAYMENT, Me.txtCardID.Text) Me.taExistingPayment.Fill(Me.DsPaymentProcessing.EXISTING_PAYMENT, Me.txtCardID.Text) Me.taInvoices.Fill(Me.DsPaymentProcessing.INVOICE, Me.txtCardID.Text) What I need to do is lock all the records that are opened in the latter 3 lines and begin a transaction. Then allow the user with the lock to add records to the first table and modify contents of the next 3. I'd prefer that other users simply not be allowed to even view these locked records. Saving needs to be in a transaction, meaning either save ALL 4 tables or fail on all. I can do this is I do everything programmatically, but I'm a bit lost when it comes to using objects from my Datasource window. I'd appreciate any help.

    - Using the Windows password in my application I have a WinForms C# application for which I currently have two methods of login - either the user enters their password when they log in, which I store in my SQL 2005 db encrypted, or I just let them in based on their windows login id. In both cases I do not ask for a username, I get this from their Windows network login. What I would like to do is something that I have seen other applications (Lotus Notes) do. If your application password is the same as your windows password, it just lets you in, but if they are different then you must enter the application password. I am not worried about the db login, just the application login. I have been searching for an example of this, but I have not had any luck. If this question has been already asked and answered, my apologies, but please point me in the right direction. Later I will need to do the same thing in an asp.net application, but right now my problem is only winforms. Any help would be appreciated.

    - Dump controles to image /saving to image I have a SplitContainer with two custom controls in it, what I'd like to do is to dump the whole thing to an image, like if you take a screenshot and cut away all but the SplitContainer. I've read somewhere that you could do something like this by creating an image and the get an Graphics object from the image and let the controls draw on that. I understand that since the SplitContainer is a standard control this might not be possible, but I can change the two controls if necessary, just as long as I can find a way to specify where the controls will draw on the image. My problem is that after looking at System.Drawing.Image and not having found any way to get a Graphics objects from I'm not sure where to start, so any pointers, example, or such would be much appreciated.

    - Need Help with Variables and Databinding I am creating an application that provides a full-text search on a db. The full-text search works fine and loads some brief descriptive data into DataGridView1. The user then selects a row and the SectionText column of text is loaded into DisplayTextBox. I make two calls to the db to speed it up. The SectionText column can be several pages long and slows the search down significantly so I bring back only what is need on the second call. At this point I need help with two problems: Problem #1. Transferring string data from the DataGridView1 (Record1 & Record2). If I put these variables into Textbox3 and TextBox5 and then use that in the WHERE clause, it works but is clumsly. I would prefer to work directly with these variables if I can get the syntax right. Problem #2: Although DataGridView1 and DisplayTextBox fill with the appropriate data as a result of the search, when I select a row in DataGridview1 I get this error message: DisplayTextBox.DataBindings.Add("Text", ds.Tables(0), "SectionText") ARGUMENTEXCEPTION WAS UNHANDLED.

    - updating DataGridView when underlying data has changed Argh. I know the answer will be simple. Am trying to get comfortable with DataGridView. I have a simple list whose contents are displayed in a Win Form DataGridView. The form has a button that modifies a list element directly, and those mods are reflected in the DGV. However, the button also adds a new element to the list, and I can't cause a new row to appear in the DGV. How do I do that Here's the code that updates the list and tries to update the DGV control. You can see I tried modifying the DGV row count directly, but that tossed an exception about modifying RowCount property on a data-bound DataGridView control. private void addBtn_Click( object sender, EventArgs e) { TrimRegister newStuff; newStuff = new TrimRegister (nameTxtBx.Text, int .Parse(wordTxtBx.Text), int .Parse(lsbitTxtBx.Text), int .Parse(numBitsTxtBx.Text), int .Parse(selectedValueTxtBx.Text)); myRegList.Add(newStuff); //dataGridView1.RowCount = myRegList.Count; myRegList[0].NumBits++; myRegList[0].LSBit++; myRegList[0].SelectedValue++; myRegList[0].Word++; dataGridView1.Refresh(); } Tag: Windows Forms General TreeView Comtrol: Add buttons to nodes in TreeView control Windows Forms

Hi,Frank

You can try implementing a custom node inherited from the TreeNode class,but I think there's a lot of work to do, have a look at this thread in ASP.NET forum,I recommend you to post asp.net problems on that forum for better responses, this forum is mainly for windows form application development.However, I wonder why do you want to add buttons to nodes, does the click event on node not enough

Hope it helps.
Best Regards.
