Folks,

Environment: RadControls for ASP.NET AJAX Q3 2009 / VS 2008 SP1/IE7/WINXP SP 2.

Is it possible to open Rad Window from Radgrid CommandItemTemplate for both Insert and Update. I would like to customize this page (Window / Edit Dialog for RadGrid: http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandwindow/defaultcs.aspx?product=window).

Thanks

below is my commanditemtemplate:

    
            <CommandItemTemplate> 
        
             <div style="padding: 5px 5px;">  
        
             Custom command item template for Grid&nbsp;&nbsp;&nbsp;&nbsp;  
        
             <asp:LinkButton ID="btnEditSelected" runat="server" CommandName="EditSelected"   
        
             Visible='<%# RadGrid1.EditIndexes.Count == 0 %>'><img style="border:0px;vertical-align:middle;" alt="" src="Images/Edit.gif" /> Edit selected</asp:LinkButton>&nbsp;&nbsp;  
        
             <asp:LinkButton ID="btnUpdateEdited" runat="server" CommandName="UpdateEdited" Visible='<%# RadGrid1.EditIndexes.Count > 0 %>'><img style="border:0px;vertical-align:middle;" alt="" src="Images/Update.gif" /> Update</asp:LinkButton>&nbsp;&nbsp;  
        
             <asp:LinkButton ID="btnCancel" runat="server" CommandName="CancelAll" Visible='<%# RadGrid1.EditIndexes.Count > 0 || RadGrid1.MasterTableView.IsItemInserted %>'><img style="border:0px;vertical-align:middle;" alt="" src="Images/Cancel.gif" /> Cancel editing</asp:LinkButton>&nbsp;&nbsp;  
        
             ''''  
        
             ''''  
        
              New Link Button or href to add new rows via Radwindow->Radgrid.                          
        
              New Link Button or href to edit existing rows via Radwindow->Radgrid.  

              For Editing existings rows, the Visible property should be: Visible='<%# RadGrid1.EditIndexes.Count == 0 %>',  

              the same as above LinkButton ID="btnEditSelected".  My intention is prior to editing, users must select a Row from current RadGrid..
        
              ''''

              ''''

            </div> 
        
            </CommandItemTemplate>

Hello,

You can directly attach the client onclick event to the LinkButtons for update/insert. Then in the event handler (for update button) access the RadGrid and get the selected item and keyvalue from client side. You can use the following client code to get the selected row.

javascript:

                             
            var grid = $find("<%=RadGrid1.ClientID %>");         
            var MasterTable = grid.get_masterTableView();         
            var selectedRows = MasterTable.get_selectedItems();         
            var row = selectedRows[0];         

Then open the radwindow using same approach described in the online demo, by passing the parameters.

Please let me know if you have any doubts in my suggestion,

Shinu.

Shinu,

I am sorry I did not understand your suggestion completely.  All I want is to move this EditLink in commandItemTemplate with its existing functionality remains the same as in this Telerik Example.

Thanks

Hi,

Here is the code that I tried for same scenario.

ASPX:

    
                <CommandItemTemplate>
 
                    <a href="#" onclick="return ShowInsertForm();">Add New Record</a>
 
                    <a href="#" onclick="return ShowEditForm();">Edit Selected</a>
 
                </CommandItemTemplate>

JavaScript:

    
                    function ShowEditForm() {
 
                        var grid = $find("<%= RadGrid1.ClientID %>");
 
                        var masterTableView = grid.get_masterTableView();
 
                        // var row = masterTableView.get_selectedItems()[0];
 
                        var id = masterTableView.get_selectedItems()[0].getDataKeyValue('CustomerID');
 
                        window.radopen("Window.aspx?CustomerID=" + id, "UserListDialog");
 
                    }

Hope this help :)

Shinu.

Thanks Shinu,

There is One problem; if users do not select any row and just click the href column in CommandItemTemplate of RadGrid, attached exception error occurs.

Is there anyway to prevent this from happening (i.e. do not allow open the RadWindow if no rows has been selected or there are no rows in RadGrid to Display).

Below is my Command Item Template/MasterTableView Declaration and Window Open Function:

Thanks again for all your help.

Hi gc_0620,

You could use a simple check if masterTableView.get_selectedItems()[0] is null and to open the radwindow only if it isn't.

Hi, I tried this, but as I ws debugign I noticed the ShowInsertForm and ShowEditForm were not reading the radwindows in the radwindow manager. So it is not getting the properties I set. How can I fix that?

Hi Carina,

Such a problem may occur if you have more than one RadWindowManager on the page, so the wrong one is used. This help article treats this case, shows how to confirm if this is indeed the problem and offers a solution. I hope it will help you.

All the best,
