Edit Item in DropDownList

[AT76]

Hi,

I have a DropDownList with 3 string items. Is there a way to edit the text of of one of the items in my list?

Thanks!

this.my_combo_box.Items[0] = "This is number one";
this.my_combo_box.Items[1] = "This is number two";
this.my_combo_box.Items[2] = "This is number three";

Thanks gplusplus! If you can do it by way of index, my next question is how would find the index of a particular field if you know the text?

OK, I got it using a for loop! Thanks for your help!

string key = "This is the text i want";

for(int i = 0; i < this.my_combo_box.Items.Count; i++)
{
     if(this.my_combo_box.Items[i].ToString() == key )
     {
         MessageBox.Show("Found at :: " + i.toString());
              return;

     }
}

Why use a loop when the functionality is already built into the ComboBox?

I'll leave you to convert this from VB to C#

either:

    Dim position As Integer = ComboBox1.FindStringExact("<TextToFind>")
    If position >= 0 Then ComboBox1.Items(position) = "<ReplacementText>"

or:

    Dim position As Integer = ComboBox1.FindString("<TextToFind>")
    If position >= 0 Then ComboBox1.Items(position) = "<ReplacementText>"

Hope this helps

thank you all...

Earthandfire, I'm trying to apply your approach but in c#, my dropdownlist does not have builtin functions FindString or FindStringExact. Is a ComboBox the same as a DropDownList? Thanks!

I missed that in you original post -sorry. I know nothing about ASP.NET or its controls.

That's just because in C# combobox lists objects, not strings. Kinda stupid looking for those coming from C++ to be honest.

When you do it, do it right.
