hi all

I am using asp.net 2.0 with C#. I have a link button in a grid viewlike this

 

 

 

 

<asp:TemplateField HeaderText="Reject">

 

<ItemTemplate>

 

<asp:LinkButton ID="lnbSelect" runat="server" CausesValidation="False" CommandName="Select"

EnableTheming="false" OnClientClick="confirmReject" OnClick="lnbSelect_Click" Text="Select"></asp:LinkButton>  </ItemTemplate>

</asp:TemplateField>

 

 

 

but i am not able to get its selecteddatakey in rowCommand event handler

 

protected void gvRequests_RowCommand(object sender, GridViewCommandEventArgs e)

{

int ReqNo;

 

GridViewRow

selectedRow = (GridViewRow)((LinkButton

)e.CommandSource).NamingContainer;

int

index = selectedRow.RowIndex;

ReqNo =

Convert.ToInt32(gvRequests.SelectedDataKey["ReqNo"

].ToString());

 

}

 

im getting error "object reference not set to an instance of object" 

 

 

 

The Button_Click doesn't select the row. (Or at least, it doesn't before the RowCommand event fires.) So the GridView will not have a SelectedDataKey.
However, chances are that e.CommandArgument is the RowIndex of the Row the Button is in.
If the Select works, then you could handle the SelectedIndexChanged, that fires after the Row is selected.
