(code behind is in C#, btw)

drop down list has several values.

In the code behind I want to programmatically select one of them based-upon the "friendly" value, not the ID:

rendered html:
<select name="ctl08$ddlBpoType" id="ctl08_ddlBpoType" style="width:300px;">
	<option selected="selected" value="0">Unassigned</option>
	<option value="223">3rd Opinion</option>
	<option value="219">Appraisal</option>
	<option value="1809">CMA</option>
	<option value="222">Drive By</option>
	<option value="218">ListingAgent</option>
	<option value="913">ListingAgent Updated</option>
	<option value="220">Supplemental</option>
	<option value="1927">VRR</option>

</select>

Open in new window



ddlBpoType.SelectedValue = "Supplemental";

does not work, but

ddlBpoType.SelectedValue = "220";

does.


Except i don't want to use "220" because it might not be "220".

I want to get to the "220" value by using the friendly name of "Supplemental".

Try this
string selectedItem= ddlBpoType.SelectedItem.Text

AND

If you want to set the  item as selected in DropDown then try this

dropdownlist.Items.FindByValue(value).Selected = true;

You can make use of FindByText method and take index of ListItem in dropdownlist using IndexOf method :

Dim li As ListItem

        li = ddlBpoType.Items.FindByText(CycleNo1.Text)
        ddlBpoType.SelectedIndex = ddlBpoType.Items.IndexOf(li)
