Hi,

i want to perform several things (like checking and correcting automatically 
the lenght of a multiline textbox in order to avoid Truncate error, removing 
automatically "<" and "'" to avoid "potential danger" error etc ..) with 
javascript on a gridview.

If i take in the aspx file this:
<asp:CommandField ShowEditButton="True">
i have no possibility to use the OnClientClick property.

So i made some Templatefields like this:
<asp:TemplateField><ItemTemplate>
<asp:LinkButton ID="lb1" runat="server" CommandName="Edit" 
 ></asp:LinkButton>
</ItemTemplate></asp:TemplateField>

<asp:TemplateField><EditItemTemplate>
<asp:LinkButton ID="lb2" runat="server" CommandName="Update" 
OnClientClick="myfunction();"></asp:LinkButton>
</EditItemTemplate></asp:TemplateField>

<asp:TemplateField><EditItemTemplate>
<asp:LinkButton ID="lb3" runat="server" CommandName="Cancel" 
 ></asp:LinkButton>
</EditItemTemplate></asp:TemplateField>

My problem is now that the linkbutton "Edit" not only appears in normal 
mode, but also in Edit mode, together with "Update" and "Cancel"..

I can make it invisible in code-behind, but then there is still an empty 
space or column in the gridview.

Any way to solve this?
Thanks
Mark

Hi,

couldn't you just set myGrid.Columns(x).Visible = False where x is the index 
of the column  you wish to hide, when you don't want the LinkButton to be 
displayed. That would hide the entire column, not just the control.

Hi, thanks for replying.

I tried this:

Protected Sub GridView1_RowCreated(ByVal sender As Object, ByVal e As 
System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowCreated
 If (e.Row.RowState And DataControlRowState.Edit) = DataControlRowState.Edit 
Then
 If e.Row.RowType = DataControlRowType.DataRow Then
Dim lb As LinkButton
lb = e.Row.FindControl("lb2")
lb.Visible = False
....

But there is still an empty column in the selected row and "Edit" is shown 
in all not selected rows.

I also tried this:
Protected Sub GridView1_RowCreated(ByVal sender As Object, ByVal e As 
System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowCreated
 If (e.Row.RowState And DataControlRowState.Edit) = DataControlRowState.Edit 
Then
  GridView1.Columns(1).Visible = False

but this gives the error: Object reference not set to an instance of an 
object.

Hi,

I think cannot use it until the grid has been databound though not 100% 
sure. Try after calling DataBind()

I tried this:
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As 
System.Web.UI.WebControls.GridViewRowEventArgs) Handles 
GridView1.RowDataBound
        If (e.Row.RowState And DataControlRowState.Edit) = 
DataControlRowState.Edit Then
            Dim lb As LinkButton
            lb = e.Row.FindControl("lb2")
            lb.Visible = False
        End If
    End Sub
but same result: the column is only empty (with a gap) in the selected row.

I also tried this:

Sub GridView1_DataBound doesn't accept the line:
"   If (e.Row.RowState And DataControlRowState.Edit) = 
DataControlRowState.Edit Then"

It seems to be a though case ...
