Find Control In row Command event of gridview[^]

this is my code.use this help full

protected void gvViewUser_RowCommand(object sender, GridViewCommandEventArgs e)
{
try
{
if (e.CommandName == "delete")
{
GridView gv = (GridView)(Object)sender;
HiddenField hfAccid = (HiddenField)gv.NamingContainer.FindControl("hfAccid");
int res = objAccAssign.DeleteAssignAccount(int.Parse(hfAccid.Value), int.Parse(e.CommandArgument.ToString()));

if (res > 0)
{
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "Msg", "alert('User removed successfully !!')", true);
}
else
{
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "Msg", "alert('User removed failed !!')", true);
}


DataTable dt = objAccAssign.getGridForDataList(hfAccid.Value);

bindGrid(gv, dt);
}
}
catch (Exception ex)
{


}
}

First u have to give CommandName and CommandArgument property in source file like this

<Columns>
   <asp:TemplateField>
   <ItemTemplate>

       <asp:LinkButton ID="LBviewreport" CommandName="Viewreport" CommandArgument='<%#Eval("Your Table Column Name") %>' runat="server">View Report</asp:LinkButton>

       </ItemTemplate>

   </asp:TemplateField>

then on rowcommand event

protected void GridView_RowCommand(object sender, GridViewCommandEventArgs e)
   {
       if (e.CommandName == "Viewreport")
       {
           string str =  e.CommandArgument.ToString();
             //write Your conditions
                  }
}
