Hi Yoon-Ho Choi,

You can try the following code in order to set the Visibility according to the RadComboBox item that user selects.

aspx:

<EditFormSettings EditFormType="Template">
    <FormTemplate>
        <telerik:RadComboBox ID="RadComboBox1" runat="server" AutoPostBack="True" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">
            <Items>
                <telerik:RadComboBoxItem Text="Item1" Value="Value1" />
                <telerik:RadComboBoxItem Text="Item2" Value="Value2" />
            </Items>
        </telerik:RadComboBox>
        <asp:TextBox ID="TextBox1" runat="server" Visible="False"></asp:TextBox>
    </FormTemplate>
</EditFormSettings>

cs:

protected void RadComboBox1_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
{
    RadComboBox combo = (RadComboBox)o;
    GridEditFormItem editItem = (GridEditFormItem)combo.NamingContainer;
    TextBox textbox1 = (TextBox)editItem.FindControl("TextBox1");
    if (e.Text == "Item1")
    {
        textbox1.Visible = true;
    }
    else if (e.Text == "Item2")
    {
        textbox1.Visible = false;
    }
}

Hello,

You can either the set the back-color from the aspx declaratively or from code by accessing the item and setting the style as required.

Here is the code for setting the color declaratevely,
aspx:

      . . .
    <telerik:GridBoundColumn DataField="CompanyName" HeaderText="CompanyName" SortExpression="CompanyName"
        UniqueName="CompanyName">
        <ItemStyle BackColor="Blue" />
    </telerik:GridBoundColumn>
      . . .

And from code behind,
cs:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if ((e.Item is GridDataItem))
        {
            GridDataItem item = (GridDataItem)e.Item;
            item["CompanyName"].BackColor = System.Drawing.Color.Blue;
        }
    }

Thanks,
Princy.
