    I've a radgrid where there are checkboxex. The data comes from database. On of the value is "OTHERS". I want that when user checks the "OTHERS" checkbox, textbox should appear by its side. How can it be done using JAVASCRIPT or by using any radgrid property like OnPreRender ?


    <telerik:RadGrid ID="grid_diag_group" runat="server"                       
                            HeaderStyle-HorizontalAlign="Left" >
                                    <telerik:GridTemplateColumn UniqueName="TempCol1" HeaderText="Select" ReadOnly="true">
                                            <asp:CheckBox ID="CheckBox1" runat="server" />
                                            <asp:CheckBox ID="CheckBox2" runat="server" />
                                    <telerik:GridBoundColumn DataField="diag_code" Display="false" Visible="true" AutoPostBackOnFilter="false" ItemStyle-HorizontalAlign="Left" CurrentFilterFunction="Contains" />                              
                                    <telerik:GridBoundColumn DataField="diag_desc" UniqueName="diag_description" HeaderText="Diagnosis"
                                        AutoPostBackOnFilter="false" ItemStyle-HorizontalAlign="Left" />

     My UI looks like this >> ( checkbox == [])

    []  MALARIA
    []  T.B.
    []  GLYCOMA
    []  MEASELES
    []  OTHERS
    When user checks the OTHERS checkbox, textbox should appear beside "OTHERS" inside the grid. How can I do it?  

    Please help !!! Thanks.

    Hello Hadoop,

    You can achieve this requirement by replacing the diag_code column with a Template column:

    Then, within the ItemTemplate next to the Label you will create a RadTextBox with its Visible property set to False. When the CheckBox1 is checked, you can then access the corresponding row, verify whether the text is OTHERS and if it is, you can set the Visible property of the textbox to true.

    I hope this will prove helpful.
