How to insert "--Select--" in combobox

Azamat

Hello All,

i am filling country list to Combobox.
This list comes from Database.

now I want to Insert "--Select--" at the top of combox.

i tried cmbcountry.items.insert(0,"--Select--");

but it fired exception that items collections can not be modified after datasource property is set.

Can anyone help me to sort out this problem

Thank in advance

use the following query,
this works for sure.

"(select convert(nvarchar, '(Select)') as \"field1\") union all (select field1 from table1)"

try inserting the "--Select--" in the properties of that combo box..i think it's items property(the one with the word "collection" on it's right side,, hehe sorry i don't know what it's called), any way, just type it line-per-line. since you want the "--Select--" to be on the top most, it should be on the first line.hope it helps

Hi! Call a function PopulateCountry() to bind the countries list at Page Load event. Here bind the datasource to DropdownList. Then add the code to insert "-- Select--" value at index 0. You can use the code: ListItem FirstItem = new ListItem(); FirstItem.Text = "Select EmailId"; FirstItem.Value = ""; DropDownListCountry.Items.Insert(0,FirstItem); Try this one!
