Hi There,
I have one Dropdownlist control in my asp.net project and the item where add while runtime.

The DropdownList has items like given below.

("itemcode" - "itemname")
1003 - foo
1008 - bar
1005 - some value5
1010 - some value10

So now what is need is i want to set the SelectedItem is item which STARTSWITH the code "1008" using c# or vb.net.
I dont want to use SelectedIndex because some time the index locaition of the item will be changed.

Best Regards,
Anand

...
DropDownList.Items.FindbyValue("1008").Selected = true;

itemCodeToBeSelected = "1008";
ddlList.SelectedValue = itemCodeToBeSelected;
the only thing is that the itemCodeToBeSelected has to exist in the list of values

@ragi0017 sir could you please tell me what is itemCodeToBeSelected ? is it string or ?
if its a string we cant select the listitem using only the first 4 digits "itemcode (1002)" , we have to use full item name like "1002 - an_and2"

Hi..can you post the code for your DropdownList?

You have to have a value for each record in the list. The text can be whaterver you want  but the value would be only "1002"...so ragi0017 solution would work

i was giving my solution based on some assumption that you are binding
ddl.DataValueField = "value";
ddl.DataTextField = "Text";
if you are talking that approach then my suggested approach will work as you can supply the value in the .SelectedValue and it will get selected in the dropdown list

if not then let us know i will provide you a different solution based on the text of the ddl
