Accessing controls in rad popup

[Rajz]

Hello,

We have been using Rad popup and would like to know what are the ways to access the controls in popup such as textbox, lable, dropdowns etc., before the popup is closed.

Example scenario:

Clicking edit button opens a popup window, where the user enters some data and upon clicking Save button, each control is to be validated server side-using cs or client side using/javascript before the popup is closed.

Appropriate message is to be displayed in the popup itself in case of any validation violation

Thank you

Regards
Raj

Hello Raj,

I assume that you are using Editmode "Popup" for RadGrid. Please take a look at the following documentation which explains how to add validator to an edit field in that case.

Adding a validator to an edit field in Telerik RadGrid

In the case of you are using RadWindow control to edit the record, then it is easy to access the controls on that page which is shown in RadWindow. The controls will be directly available on page and you can access those either from client or server in that page.

Thanks,
Princy.

Hi Rajz,

The code provided in the help article for adding a required field validator to an edit form of RadGrid is the following (in case you are editing a bound column):

protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
  if(e.Item is GridEditableItem && e.Item.IsInEditMode)
  {
     GridEditableItem item = e.Item as GridEditableItem;
     GridTextBoxColumnEditor editor = (GridTextBoxColumnEditor)item.EditManager.GetColumnEditor( "ContactName");
     TableCell cell = (TableCell)editor.TextBoxControl.Parent;

     RequiredFieldValidator validator = new RequiredFieldValidator();
     editor.TextBoxControl.ID = "ID_for_validation";
     validator.ControlToValidate = editor.TextBoxControl.ID;
     validator.ErrorMessage = "*";
     cell.Controls.Add(validator);
  }
}

The sample set up for a template column is:

<telerik:RadGrid id="RadGrid1" runat="server">
  <MasterTableView AutoGenerateColumns="False">
   <Columns>
    <telerik:GridTemplateColumn HeaderText="ContactName" UniqueName="TemplateColumn">
     <EditItemTemplate>
      <asp:TextBox id="TextBox1" runat="server" Text='<%# Bind("ContactName") %>'></asp:TextBox>
      <asp:RequiredFieldValidator id="RequiredFieldValidator1" runat="server" ErrorMessage="*"
       ControlToValidate= "TextBox1"></asp:RequiredFieldValidator>
     </EditItemTemplate>
     <ItemTemplate>
      <asp:Label id="Label1" runat="server" Text='<%# Eval("ContactName") %>'></asp:Label>
     </ItemTemplate>
    </telerik:GridTemplateColumn>
    <telerik:GridEditCommandColumn UniqueName="EditCommandColumn"></telerik:GridEditCommandColumn>
   </Columns>
  </MasterTableView>
 </telerik:RadGrid>

There is other useful information in that article as well, so I advise you that you try to open it again (maybe in a different browser than the previous time). The link in Princy's post is correct and opens the page without any errors on my side.

Sincerely yours,
