Finding an index in a dataset and setting SelectedIndex on dropdownlist

wrecker

Hi all,

I have a dataset bound to a dropdownlist and I'm trying to get the
dropdownlist to start off with a default value selected (not the first
value). Is there any way that I can retrieve the index of the item I
want from the dataset and use this to set the SelectedIndex of the
dropdownlist? I've tried creating a dataview from the dataset and
sorting it and then using the return value of DataView.Find() method
to set the index but it doesn't seem to set the index correctly
(probably because it is now sorted?). Is the only way to iterate
through the dataset until I find the row I want?

Thanks

Rene

I've found I have this to work well for me:

make sure this is AFTER you call MySel.Databind() to load the DropDownList

1) MySel.SelectedIndex =
MySel.Items.IndexOf(MySel.Items.FindByText(strToFind.ToUpper()))
or
2) you can set the VALUE of each item to Upper case when loading the
DropDownList and then
MySel.SelectedIndex =
MySel.Items.IndexOf(MySel.Items.FindByValue(strToFind.ToUpper()))

Hope this helps!

Didn't Eertha Kitts sing something along that line?
And a big stir it caused, BTW)
