making html table row invisible in editform mode

[Henk]

Hi,

I have a radgrid and in editform mode I have define a table with rows and columns. For some grouping condition in the radgrid I want to make a row invisible. I try in the itemcommand or itemdatabound using  Table mytable=<>.findcontrol("tableID")  as Table; and for example myTable..Rows[0].Visible = false;  and but I see myTable is alway null....

                if (AftekenTabl != null) <--- But it is always null !!!
                AftekenTabl.Rows[0].Visible = false;
            }

        }

        protected void DocWerkVAftekenGrid_ItemCommand(object sender, GridCommandEventArgs e)
        {
            if (e.CommandName == "Edit")
            {
             GridEditableItem editedItem = e.Item as GridEditableItem;
             Table AftekenTabl = editedItem.FindControl("AftekenTable") as Table;
             if (AftekenTabl != null)  <-- also null thus not working....
                 AftekenTabl.Rows[0].Visible = false;

            }

        }

How can I achieve that the row "eenheid"and "score"is invisible when group column is equal to some condtion?

Thanks in advance,

Henk

Hello Henk,

The table cannot be accessed on the server as it is not a server control. If you would like to get reference to the table rows server-side you could add runat="server" to the tr elements. After this you would be able to get reference to the table rows on the server and set their Visible property. Check the following snippets for illustration:

Markup for the Score row:

<tr id="score" runat="server">
    <td>Score</td>
    <td>
        <asp:TextBox ID="ScoreTextBox" runat="server" Text='asda' runat="server" />
    </td>
</tr>

ItemDataBound handler:

Protected Sub RadGrid1_ItemDataBound(sender As Object, e As GridItemEventArgs)
    If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then
        Dim editItem As GridEditableItem = TryCast(e.Item, GridEditableItem)

        editItem.FindControl("score").Visible = False
    End If
End Sub
