Dbl click on radgrid

[Ayesha]

Hi,

I'm having an usercontrol(.ascx) where I need to double click on a grid and it needs to open up another usercontrol.

I do the following: in .ascx

<

 

script type="text/javascript">

 

 

function RowDoubleClick(index)

 

{

__doPostBack(

"<%= this.UniqueID %>", "RowDblClicked:" + this.Rows[index].ItemIndex);

 

}
</script>
in client events I do,

 

 

<ClientEvents OnRowDblClick="RowDoubleClick"></ClientEvents>

 

 

 

and in ascx.cs file, I do this,

 

 

public partial class CPackageMainUserControl : BaseUserControl, IPostBackEventHandler
{

 

 

void IPostBackEventHandler.RaisePostBackEvent(string eventArgument)

 

{

 

string[] postBackEventArgumentData = eventArgument.Split(':');

 

 

switch (postBackEventArgumentData[0])

 

{

 

case "RowDblClicked":

 

m_ctlPackageGroupMultiView.SetActiveView(m_ctlPackageSetUpView);

m_ctlPackageSetupUserCtrl.LoadNonDocPredefinedReports();

 

break;

 

}

}
}

(because in my cause when i dbl click on a row in a radgrid , I need to setactiveview to openup another view).

But when i do all this and try to run , I get a javascript message :

Microsoft JScript runtime error: 'this.Rows' is null or not an object.

Pls help me and correct my code and let me know what to do .
Thanks,
ZR

Hi Zaheka,

Are you using RadGrid for asp.net or RadGrid for asp.net AJAX version? I guess the above given code will work only with RadGrid for asp.net version. If you are using RadGrid for asp.net AJAX version try with the following approach and see whether it is working.

JS:

function RowDoubleClick(sender, eventArgs)
{

  __doPostBack("<%= RadGrid1.UniqueID %>", "RowClicked:" + eventArgs.get_itemIndexHierarchical());

}

Thanks

Hi Zaheka,

The code is working fine in my end. I am not sure about what is happening in your side. Can you try passing the ' index ' rather than ' this.Rows[index].ItemIndex ' to the postback method and see whether it is working fine?
