Hi Shweta,

I guess that you want to truncate the GridTemplateColumn Text, please have a look into the sample code snippet which works fine at my end.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" AutoGenerateColumns="false">
    <MasterTableView>
        <Columns>
            <telerik:GridTemplateColumn DataField="ShipName" UniqueName="ShipName" HeaderText="ShipName">
                <ItemTemplate>
                    <asp:Label ID="Label1" runat="server" Text='<%# Eval("ShipName")%>'
                    </asp:Label>
                </ItemTemplate>
            </telerik:GridTemplateColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

JavaScript:

<script type="text/javascript">
    function pageLoad() {
        var grid = $find("<%= RadGrid1.ClientID %>");
        if (grid) {
            var MasterTable = grid.get_masterTableView();
            var Rows = MasterTable.get_dataItems();
            for (var i = 0; i < Rows.length; i++) {
                var row = Rows[i];
                var label = row.findElement("Label1");
                var textvalue = label.innerText;
                if (textvalue.length > 5) {
                    textvalue = textvalue.substring(0, 5);
                }
                label.innerText = textvalue;
            }
        }
    }
</script>

Please elaborate your requirement if it doesn't help.
Thanks,

Hi Shinu,

Thanks for the reply.
But I don't want to truncate the text depending on its length. I want to display it up to 3 lines,whatever its length will be then. Remaining text will be truncated.

Hi Shweta,

Please try the following sample code snippet which works fine at my end. As a suggestion you can take the length of the text and truncate the text as follows. 

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" AutoGenerateColumns="false" Width="100px">
    <MasterTableView>
        <Columns>
            <telerik:GridBoundColumn DataField="id"  UniqueName="id" HeaderText="id">
            </telerik:GridBoundColumn>
            <telerik:GridTemplateColumn DataField="LargeData" UniqueName="LargeData" HeaderText="LargeData">
                <ItemTemplate>
                    <asp:Label ID="Label1" runat="server" Text='<%# Eval("LargeData")%>'></asp:Label>
                </ItemTemplate>
            </telerik:GridTemplateColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

JavaScript:

<script type="text/javascript">
    function pageLoad() {
        var grid = $find("<%= RadGrid1.ClientID %>");
        if (grid) {
            var MasterTable = grid.get_masterTableView();
            var Rows = MasterTable.get_dataItems();
            for (var i = 0; i < Rows.length; i++) {
                var row = Rows[i];
                var label = row.findElement("Label1");
                var textvalue = label.innerText;
                if (textvalue.length > 60) {
                    //according to your scenario you can change the substring values
                    label.innerText = textvalue.substring(0, 35);
                }
            }
        }
    }
</script>

Hope this will helps you.
Thanks,
Shinu.
