Limit length of text in Edit Mode

[Clive Hoggar]

Hi All

I have a RadGrid that uses the standard edit mode form, and I am try to complete
the validation as in the declaration shown below:

<telerik:GridTemplateColumn DataField="FirstName"
            HeaderText="FirstName" SortExpression="FirstName"
            UniqueName="FirstName">
            <EditItemTemplate>
                <asp:TextBox ID="FirstNameTextBox" runat="server"
                    Text='<%# Bind("FirstName") %>' MaxLength="25">
                    </asp:TextBox>
                <asp:RequiredFieldValidator ID="RequiredFieldValidator1"
                    runat="server"
                    ControlToValidate="FirstNameTextBox"
                    Display="Dynamic"
                    ErrorMessage="First name required"
                    SetFocusOnError="True"></asp:RequiredFieldValidator>
                <asp:RegularExpressionValidator ID="RegularExpressionValidator1"
                    runat="server" Display="Dynamic"
                    ErrorMessage="Illegal characters"
                    SetFocusOnError="True"
                    ValidationExpression="^[a-zA-Z0-9 \-]+$"  ControlToValidate="FirstNameTextBox"></asp:RegularExpressionValidator>
            </EditItemTemplate>

The problem is that when the MaxLength property is set it prevents any chacters being entered in Edit mode. Insert Mode is OK

So I took that property out and used code behind like this:

Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs)
        If TypeOf e.Item Is GridDataItem Then
            Dim dataItem As GridDataItem = DirectCast(e.Item, GridDataItem)
            Dim txtbx As TextBox = DirectCast(dataItem.FindControl("FirstNameTextBox"), TextBox)
            Dim strtxt As String = txtbx.Text
            If strtxt.Length > 25 Then
                txtbx.Text = strtxt.Remove(25)
            End If
        End If
        If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then
            Dim editItem As GridEditableItem = DirectCast(e.Item, GridEditableItem)
            Dim txtbx1 As TextBox = DirectCast(editItem.FindControl("FirstNameTextBox"), TextBox)
            Dim strtxt1 As String = txtbx1.Text
            If strtxt1.Length > 25 Then
                txtbx1.Text = strtxt1.Remove(25)
            End If
        End If
    End Sub

But that did not have any effect at all.

What I am doing worng here?

Thanks

Hi,

I 'm a bit confused with your question.As far as I know the MaxLength property prevents a user from entering more than the specified length.This is working at my end using your exact scenario. The code you have used tries to truncate the bound data for the datafield when the grid is in edit mode,if  the text length exceeds the specified limit.
Which of these are you trying to achieve?

Thanks,
