ActiveCell is null sometimes
posted

my code is:

protected void WebDataGrid1_ItemCommand(object sender, Infragistics.Web.UI.GridControls.HandleCommandEventArgs e)
{
GridRecordItem item = WebDataGrid1.Behaviors.Activation.ActiveCell;
if (item == null)
return;

......

}

in aspx code, The grid control bound a column as follow:

<ig:TemplateDataField Key="Operation" Width="40px">
<ItemTemplate>
<center>
<asp:LinkButton ID="LinkButtonMapping" runat="server" Font-Underline="True" 
ForeColor="#0000CC" CommandName="update" >name1</asp:LinkButton>
</center>
</ItemTemplate>
<Header Text="Operate" />
</ig:TemplateDataField>

My question is:

The ActiveCell is null sometimes when I click link "update" in the grid. But sometimes ActiveCell is not null.  I do not know why.

The grid has 20000 datas and has Paging behavior.

    Hello foxbabby,

    Thank you for posting in the community.

    I have tested this scenario using version 12.1.20121.1005 but so far am unable to replicate the described behavior. It would be helpful to know if there are specific steps to be undertaken under which the ActiveCell is returned as null.

    Please do not hesitate to contact me with any updates or additional questions regarding this scenario.
