Hi,

I have a weird issue on one drop down list.
It has databound items and is dependant on another dropdownlist.
So if I select a value from the 1st dropdown list then this dropdownlist in question will have databound items.

the issue that I am having is that I want to add a value at index 0 that says "ALL" and there after display the databound items but this is not working. I have it working for the rest of the dropdowns beside this 1.

here is my code:

C#

ddlPromoSuffEdit.Items.Clear();
ddlPromoSuffEdit.Items.Add(new ListItem("All", "")); //this is not being added in but data items are populated
ddlPromoSuffEdit.DataSourceID = "";
ddlPromoSuffEdit.DataSource = odsPromoSuffEdit.Select();
ddlPromoSuffEdit.DataBind();

Hi,

If you DataBind() your list before inserting the new ListItem you should find it will display as requested.

Something like this should work:

C#

ddlPromoSuffEdit.Items.Clear();
ddlPromoSuffEdit.DataSourceID = "";
ddlPromoSuffEdit.DataSource = odsPromoSuffEdit.Select();
ddlPromoSuffEdit.DataBind();
//Insert new ListItem ... 
ddlPromoSuffEdit.Items.Insert(0, (new ListItem("All", "")));

... hope it helps.

Then you have other issue. Please debug and watch the items after this code.
