[Solved] how to find GridEditCommandColumn in code-behind

[beigel]

Hello,

I have a RadGrid with GridEditCommandColumn inside ajaxToolkit:ModalPopupExtender panel. RadGrid is populated with asp ObjectDataSource, which has insert/update/delete methods triggered every time I click on a button in RadGrid ('Edit' button of the GridEditCommandColumn, for example). When an Update event is fired, all my controls inside the panel and including the panel itself are null, so I found a workaround and use RadGrid_ItemCommand function instead. This way I can set and validate my contols, and I can get an index in the grid and an event name fired.

My problem is that I have to use Request.Params to find changed Name on Edit, and this is not a good programming practice (even though it works). How can I replace Request.Params or at least set a name for the GridEditCommandColumn?

 

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
{
...

if (Request.Params["__EVENTTARGET"].Contains("UpdateButton"))

{ 

 

 

int index = e.Item.DataSetIndex;

 

int locationID = CurrentClub.Locations[index].LocationId;

ValidateUpdatedItem(locationID, Request.Params.Get(

 

 

"ctl00$ctl00$phBody$phBody$ucEditEventLoc$rgLocations$ctl00$ctl09$ctl00"));

}

 

 

else

 

if (Request.Params["__EVENTTARGET"].Contains("PerformInsertButton"))

ValidateNewItem(Request.Params.Get(

 

 

"ctl00$ctl00$phBody$phBody$ucEditEventLoc$rgLocations$ctl00$ctl02$ctl02$ctl00"));
}

Hello beigel,

You can detect the update command/insert command inside the ItemCommand handler by checking whether e.CommandName is RadGrid.UpdateCommandName or RadGrid.PerformInsertCommandName. See the information from this documentation article for more details.

Okey, thank you

This way I can get my event name, but what about Edit text box name and value? How can I pull that info without using Request.Params?

ValidateUpdatedItem(locationID, Request.Params.Get("ctl00$ctl00$phBody$phBody$ucEditEventLoc$rgLocations$ctl00$ctl09$ctl00"));


Thank you!

Hello beigel,

How to extract the new values from the edited/inserted grid item you can see from the following online demos of  the product:

http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/extractvalues/defaultcs.aspx
http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/editmodes/defaultcs.aspx

Review the code snippets in the UpdateCommand/InsertCommand/ItemCommand handlers for more details.
