Updating and binding control to other controls within the same row of a Grid View Hi In the Edit Template of my Grid View I show 2 Drop Down Lists. Right now I everything working fine except when the grid get over 20 items in it the process slows down horribly.When the user selects the first dropdownlist, I need it to update the contents of the second dropdownlist. The reason why is because on every postback I'm looping though the grid and making sure that the next dropdown only contains items that are filtered on the previous dropdown.I would need to set values passed to the Sql Data Source control on the update event, and as part of this I would need to reference the controls contained in the row being updated. To do this, I created an instance of the Row Updating event for the Grid View. David I suggested that the Row Updating function was being blocked by the . Data Bind() in the Row Command event so that only the Edit command will activate it (take it out of Row Editing). Twice for Row Command (1 for Row Editing and 1 for Row Canceling) and once for Row Editing. I am going to try and create this not as a web application but rather as a website and see if I notice any differences.

I am confused at this point on why my markup and code behind is not touching the Row Updating event when Update button is clicked. I subsequently changed the code behind to explicitly bind to the product table during Row Cancel and Row Edit events.I also don't understand when I select the grid View control and look at the events in the Properties window of Visual Studio 2010 why I see all the proper event procedures listed for each event I expect to use. The Row Update event will load a copy of the product table from the database after successfully updating a row.The Edit, Delete and Insert events work as I expect. The markup and code behind are as follows: Hi cpkilekofp; I removed the Insert command button and put in an event for Command to see if the Update button press in the grid View control would trigger the Command event - it did not. My markup and code look as follows and the Update event is not firing: Kesha Williams, certified professional and software developer, explores the imbalance of diversity in the world of technology -- especially when it comes to hiring women. The routine loading of the product table now happens only on the first pass through the code behind.That is, you need to write some code that updates the database with the values in e. You should only modify the underlying Data Source, and then call Grid View1. Q I hope you understand my question, all i need to do is replace the text box controls with a dropdown list when i am editing a row in ... Gridview Update Only Row after indexchanged event I have a gridview with 4 dropdowns per row in the itemtemplate mode.

==================Regards, Steve new controls to a gridview row; when editing that row using the edit row feature in the gridview control. When the row is in edit mode i display a checkbox and textbox. Have a look at this link: Data in a Grid View Web Server Control).Binding form controls is mostly a simple matter of attaching a Data Source and setting your controls to reference the correct field in the Data Source.
