Getting the Selected Item of dropdownlist inside Web User Control on a Web Form
Ive got a dropdownlist control inside a web user control called Entity.ascx. This web user control is on a webform.aspx. In Entity.ascx class I created a SelectedEntity property that returns the selected item in the dropdownlist.
Inside webform.aspx when btnGo is pushed I set a string and pass it in the url. I am trying to get the entity they selected via the property (SelectedEntity) inside Entity.ascx. As the SelectedEntity property tries to return the selected item in the dropdownlist I get this error:
System.NullReferenceException: Object reference not set to an instance...Getting DropDownlist's DataTextValue Selected Value Given the SelectedValue and/or Selected Item
In the vb.net codebehind, I need to extract something from the Text (displayed) value of dropdownlist's selected item and I have the SelectedValuand and SelectedItem in hand. How can I do this?
FindControl? Item? row?
Well, its easier than you might think. SelectedItem has a "text" property. Thats the selected text right there :)
If you need the Text of the selection, then you have to use the SelectedItem.Text property. If you want the value (not the displayed text) the you can directly use the SelectedValue.

I have a web form which has Multiple select CheckBox List. In this, i have items out of which few are selected and few are unselected. Now when i select or deselect an item, SelectedIndexChanged Event is fired. I want to find out the item which fires the selectedindex changed event.
Please help me out.
One option is to examine the value of Request.Form["__EVENTTARGET"]. This carries a value as CheckBoxListID$CheckedItemIndex. E.g.: cbl$4 if 5th item is cheked or unchcked.Mark replies as answers if they helped you solve the problem....Get DataList selected item index value
