I had a DropDownList that has names as its items ("John", "Mark"). By default the SelectedIndex is "John". Upon changing its index and selecting "Mark" the event OnSelectedIndexChanged will be triggered. When I use ddlName.SelectedIndex it will return only the index for "Mark" which I want to get is the index of "John".

Forms Data Controls :: Need An Event Handler For DropdownList SelectedIndexChange Datagrid?

Aug 11, 2010

I've tried many different ways to try to get the selectedIndexChange to work for my dropdownlist. It doesn't seem to work, when I debug, I can see that the page is doing a PostBack but the method that suppose to be taking care of the select index change doesn't seems to be fired. I notice that there is no "handles" in many post so I was just wondering why it doesn't have it?On postBack I didn't rebuild the list so the selectedIndexChange value shouldn't reset to 0.Sub ddlAccess_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) ''handles ......?"

Forms Data Controls :: How To Capture A DropDownList Selected Index Change Event

Sep 15, 2010

I have a gridview that receives data based on selection from a primary dropdownlist object. Works.

Within the gridview, there is a dropdownlist whose selected index is based on the query from the primary dropdownlist. Works.

Problem.

How do I force the used to change whatever value that the dropdownlist contains after they make their initial selection from the primary dropdownlist; except the default value of "make a selection".

Gridview, contains a checkbox which drives whether a selected row is inserted into the data base. The databind in done using an ObjectDataSource on the presentation page, not in the code behind.

Jan 18, 2011

I have a formview tied to a gridview. The formview shows the data for the row selected in the gridview.

Forms Data Controls :: Retain Multiple Gridview Selection?

Jan 26, 2011

I have 3 gridviews on a page in a parent child relationship. i.e, when Grid1 is selected, any child rows will be shown in grid2. When a row is selected on grid 2 , any child rows will be shown in grid 3.

I have a single formview used for editing and inserting tied to all the 3 gridviews as they are of the same table structure.

The issue is whenever an insert or update happens on the formview, all the selection is lost. How do I retain the selection on the appropriate gridviews and also refresh only the gridview which caused the change?

For eg) when I select a row in grid 1, the child row shows up in Grid 2 . When I selected the row in Grid 2 for edit, the data appears in the formview. After I update the data in formview, when the page gets refreshed, the row in Grid2 does not remain selected. How do I retain the selection?
