CommandArgument returns empty string.

26 New Member
I have a datagrid using link button. I am setting the CommandArgument value as ..

Expand|Select|Wrap|Line Numbers
  1. <asp:linkbutton runat="server" 
  2.         EnableViewState=True 
  3.         CommandArgument='<%# DataBinder.Eval(Container.DataItem, "EmpId")%>'
  4. ....>
In the .aspx.vb file I am referring this value as..
Expand|Select|Wrap|Line Numbers
  1. Private Sub results_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles results.ItemCommand
  2.    If e.CommandName = "Delete" Then
  3.       Dim sEmpId As String = e.CommandArgument
  4.  
The sEmpId is returning empty.
But If I hard code the value of CommandArgument as..
Expand|Select|Wrap|Line Numbers
  1. <asp:linkbutton runat="server" 
  2.         EnableViewState=True 
  3.         CommandArgument='190765
  4. '....>
Its giving the correct value.. any idea why its not returning the value ?

Regards,
Renil.

Hi,

Probably ,EmpId may be containing Null for that row.You can Debug by assigning some other column.

I had this problem too, and I solved it by disabling ViewState on the LinkButton.

Hello all, My basic problem is that my LinkButton does not support a data bound CommandArgument property under certain cases. The intent is to filter my datagrid based on a specific row's value, so one query might return players from multiple schools; clicking on a player row's school linkbutton will filter the previous query to that school. The linkbuttons bind properly (including the commandArgument) when the templatecolumn is...

I have a command button in GridView row that fires the RowCommand Event when clicked. The event handler looks like this: protected void grid_RowCommand(Object sender, GridViewCommandEventArgs e) { int rowIndex = Convert.ToInt32(e.CommandArgument); When this code runs it triggers an "Input string was not in a correct format" error.

I have a template field in a GridView that contains two ImageButtons. When the user clicks one of the buttons, the GridView's RowCommand event is fired and I can get the CommandName. All that is fine. However, e.CommandArgument is an empty string, presumably because the CommandArgument property of the ImageButtons is not set. Is there some way, in the markup, to set the CommandArgument to the row index? <ItemTemplate>

Hello, I have a gridview that's bound to a generic list of business objects and am using the RowCommand event to capture user clicks on actions. This was working fine up until today, but now e.CommandArgument being passed into the RowCommand event handler is always coming back as an empty string and causing an invalid cast exception. The GridView itself has a hyperlink field to display the object name, and several TemplateFields to...
