ComboBoxes again

Katzs

I'm using a combobox as a dropdown menu to choose something, and when I run the following code:

Code Snippet

private void comboBox2_SelectedIndexChanged(object sender, EventArgs e)
{
primary = comboBox2.SelectedText;
}

and select something from the list, primary is ending up as an empty string. Why is that

Alright so I just changed the code to:

Code Snippet

private void comboBox2_SelectedIndexChanged(object sender, EventArgs e)

{

primary = comboBox2.Items[comboBox2.SelectedIndex].ToString();
}

and it works now. Could someone explain the difference

I always just do something like

Code Snippet

private void comboBox2_SelectedIndexChanged(object sender, EventArgs e)

{

primary = comboBox2.Text;
}

That depends of how you use the ComboBox control. It can work in connected or disconnected mode. If you set DataSource property, then it work connected, and if you fill it manually, then is working in so called 'disconnected' mode. From this will depend what are you reading, Text in disconnected or SelectedText(i would always use SelectedValue because that is what matters) in connected mode.

Hi, actually "this.comboBox1.SelectedText" gets the current highlighted text inside the combobox

I suppose "this.comboBox1.Text" is the one that you were looking for

Property ValueA string that represents the currently selected text in the combo box. If DropDownStyle is set to DropDownList, the return value is an empty string ("").

SelectedText is text of the editable "textbox" portion of the combobox. The selecteditem targets the "listbox" portion of the combobox. In your scenario, the later of your code snippet is precise.

Hi . as moderator replayed you , SelectedText is text of the editable "textbox" portion of the combobox. The selecteditem targets the "listbox" portion of the combobox. but i'd like to say that , it depends of how you use the ComboBox control. i mean in connected or disconnected mode. If you uses connected mode by setting DataSource SelectedText will work fine . Else you fill it manually, then is working in so called 'disconnected' mode then " Text " Property will work in this disconnected mode .
