Find controls in a grid

[Ryan]

I have 2 controls in a grid. A radio button list and a rad date picker. When a user edits or adds info into the grid they can chose between 3 options. only 1 option the date picker is enabled the other 2 options the date picker is disabled. I am trying to do this on Selected Index change on the radio button list, but I can't get the controls of either date picker or radio button list on client or server side. I tried both ways but I am not able to find the solution on this site.

Thanks

Hello Ryan,

Here's an example of a similar scenario, which would probably help you achieve the required:
aspx:

<telerik:GridTemplateColumn UniqueName="TemplateColumn1">
      <EditItemTemplate>
        <asp:RadioButtonList ID="RadioButtonList1" AutoPostBack="true" runat="server" OnSelectedIndexChanged="RadioButtonList1_SelectedIndexChanged">
            <asp:ListItem Text="Option1">
            </asp:ListItem>
            <asp:ListItem Text="Option2">
            </asp:ListItem>
            <asp:ListItem Text="Option3">
            </asp:ListItem>
         </asp:RadioButtonList>
      </EditItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn UniqueName="TemplateColumn2">
      <EditItemTemplate>
        <telerik:RadDatePicker ID="DatePicker1" Visible="false" runat="server">
        </telerik:RadDatePicker>
      </EditItemTemplate>
</telerik:GridTemplateColumn>

c#:

protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
    {
        RadioButtonList rdbtnlist = (RadioButtonList)sender;
        GridEditableItem editItem = (GridEditableItem)rdbtnlist.NamingContainer;
        if (rdbtnlist.SelectedItem.Text == "Option1")
        {
            ((RadDatePicker)editItem.FindControl("DatePicker1")).Visible = true;
        }
        else
        {
            ((RadDatePicker)editItem.FindControl("DatePicker1")).Visible = false;
        }
    }

Thanks
Princy.

Hi Princy,

I´m trying to implement your suggestion, but, the clause "NamingContainer" is not recognized.

Please, any tip?

Thanks, best

Daniel

Hello Daniel,

I am not sure about the error you are getting. The above sample code is when EditMode is InPlace. For EditForms or PopUp you should access the controls as shown below.
C#:

protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
{
        RadioButtonList rdbtnlist = (RadioButtonList)sender;
        GridEditFormItem editItem = (GridEditFormItem)rdbtnlist.NamingContainer;// when EditMode="EditForms"
        GridEditableItem item = (GridEditableItem)rdbtnlist.NamingContainer;//when EditMode="InPlace"
}

Thanks,
Princy.
