When is DDL's SelectedValue set ?

Hello!

At Page_Load I do something like this to set the default value od a DropDownList:

i = int.Parse(somethin from Session);

//e.g. i = 1000

ddlClient.SelectedValue = i.ToString();

//some code

'BREAK POINT'

When debugging at 'BREAK POINT' the SelectedValue of the DDL is always "0", but when the page finishes loading the selected value is the one provided by int i (looking at the page in a browser).

Why?

Thx

You will need to do a DataBind() before you try to set the value. The DDL does not have any items in it yet.

i = int.Parse(somethin from Session);
 
//e.g. i = 1000

ddlClient.DataBind();
 
ddlClient.SelectedValue = i.ToString();
 
//some code

How/when do you populate DropDownList?

Re: When is DDL's SelectedValue set ?

if you are populating the drop down list at load then the first item you add to it will be index 0 and will be the first selected. if you want to change that after you load the dropdown you will want to do something like dropdownlist.selectedIndex = 4

ddlClient.DataBind();
 
ddlClient.SelectedValue = i.ToString();
