[Solved] Trying to fire Item command from User Control Edit Form

[Goksun]

Hi All,

I am trying to find an answer to my problem and couldn't find anything in the forums. Here's what I'm trying to do.

I have a RadGrid and the edit form is a user control. I am adding some link buttons dynamically at run time to the edit form in Grid's Item Created event. These link buttons will be used to download different files. Here's my code to create the dynamic link button.

LinkButton lnkScriptFile = new LinkButton();

lnkScriptFile.ID =

"lnkScriptFile1";

lnkScriptFile.CommandName =

"DownloadAttachment";

lnkScriptFile.Text =

"Attachment " + (i + 1) + ": " + dtr["FileName"].ToString() + dtr["Extension"].ToString();

lnkScriptFile.CommandArgument = dtr[

"StageFileId"].ToString();

lnkScriptFile.OnClientClick =

String.Format(@"{0}.__doPostBack(""{1}"",""{2}"");", RadAjaxManager1.ClientID, lnkScriptFile.UniqueID, lnkScriptFile.CommandArgument);

pnlScriptFiles.Controls.Add(lnkScriptFile);

I am adding OnClientClick event handler to do a real postback when the button is clicked. But I also need to invoke ItemCommand event of the grid. How can I do that?

Thanks

I forgot to add that, if I add a static LinkButton on the control, ItemCommand event is fired. I just need to find out how to add the event handler.

Thanks

Hi Goksun,

Are you experience this behavior with Mozilla browser? Can you please try setting the RadGrid control as postback Target through passing its id as first parameters to the doPostBack function. I have attached a simple project that demonstrates this approach.

No, I am using IE 7. Anyway, I've changed my approach and added ResponseStart and ResponseEnd client events to the code and enable/disable AJAX based on the id of the control which fired the event. Now, dynamic link buttons fire ItemCommand.

But now, I have another problem. When I click on the link button, I have a file dialog. I have save/open/cancel options and my file is saved/opened based on the choice. And I end the Response to finish my file operation. (Http.Current.Response.End())

However, this doesn't end the response for the grid. So whatever I do afterwards, I always get the ItemCommand. The Status Bar displays "Loading".

How can I end the response (or expire it) of the grid page?

Thanks

Hello Goksun,

I'm not sure what your scenario is, so can you please send us (attached to formal support ticket) a small working project in which this behavior can be observed. This will let us understand the problem in details and provide you with more specific answer.

Meanwhile you can review this demo example on how to upload files with ajax.

Kind regards,

Hi Rosen,

Never mind, I've solved my problem by replacing Link buttons with hyperlinks. I don't need to open a support ticket for this. Thanks for your help.
