</ItemTemplate>  

 

<EditItemTemplate>  

 

<asp:TextBox ID="txtDescription" Columns="25" MaxLength="255" Rows="5" TextMode="MultiLine" Text='<%#Bind("Description")%>'

 

runat="server"></asp:TextBox>

Hello Anto,

It seems when the TextBox is set to MultiLine mode then the MaxLength propertywill not work. Instead you can use javascript code for validating the enteredcharacters. Check out the following for reference:

Restrict number of characters to be entered in the MultiLine TextBox

Thanks

Hi Shinu,

The link you send me, is for a textbox which is not inside a grid.

It doesn't work in the GridTemplateColumn.

So please can you send me any other option that works in a grid.
 
Thank You

Hello Anto,

To avoid such limitations we recommend you use RadControls - namely the RadTextBox:

<telerik:RadTextBox
    ID="RadTextBox1"
    runat="server"
    TextMode="MultiLine"
    MaxLength="5" />

Hello Anto,

You can restrict the length of the Textboxes using server code as shown below:
c#:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem dataItem = (GridDataItem)e.Item;
            TextBox txtbx = (TextBox)dataItem.FindControl("txtDescription1");
            string strtxt = txtbx.Text;
            if (strtxt.Length > 255)
            {
                txtbx.Text = strtxt.Remove(255);
            }
        }
        if (e.Item is GridEditableItem && e.Item.IsInEditMode)
        {
            GridEditableItem editItem = (GridEditableItem)e.Item;
            TextBox txtbx1 = (TextBox)editItem.FindControl("txtDescription");
            string strtxt1 = txtbx1.Text;
            if (strtxt1.Length > 255)
            {
                txtbx1.Text = strtxt1.Remove(255);
            }
        }
  }

Thanks
Princy.

Hi Daniel,

Thank You for ur reply

I have given radtextbox, it works.

But scrolling appears. Is there any option to avoid it.

Hello Anto,

It is possible to set overflow:hidden to avoid the scrollbars:

<telerik:RadTextBox
   ID="RadTextBox2"
   runat="server"
   TextMode="MultiLine"
   MaxLength="255"
   style="overflow:hidden" />
