Grid Columns Alignment/Performance Issue

Hi Telerik Team,

We are having issues in Grid Columns and Items alignment. Actually, we are doing alignment of columns and items on Grid's PreRender Event but that is not getting aligned. If we do the above process in Grid's ItemDataBound Event then this event is getting fired for every record(Item) in the DataSource which is degrading the System's Performance.

Please suggest how to do the above process while keeping System's Performance up-to-date.

Thanks,
Rajesh

[Solved] Could not load file or assembly 'Telerik.Web.UI...

Greetings, sorry to bring this issue up again. I have been researcing it for much too long now and need to ask for help.

I am demo'ing the RadControls for ASP.NET AJAX and have run into this error on my server. I am developing on a Vista Laptop with MS Visual Web Developer 2008 Express (demo'ing that too) and the trial version of RadControls. I have written a very excellent program that runs fine on my computer. The problem is when I build the site and upload the files to my server. It's like IIS cannot locate the telerik dlls in the /Bin folders.

Other Info:
I have a website set up under IIS with the /Bin folder in the root directory. My files I am playing with are also located in this directory. I have ASP.NET v3.5 installed. I found a forum about adding the dlls into the GAC but when I try to do that, it tells me the names aren't "strong."

Does anyone have a clue what I am doing wrong? I'm a programmer really so I am sure I've forgotten something or bumbled something up on the server. Any help and direction would be greatly appreciated.

Rad menu not displaying the hierarchy

I am fairly new to Rad controls. When i try to bind the rad menu to the hierarchial data source it is not displaying in the hierarchial order but instead showed all the items in a single row.

I tried to run the sample code from telerik site. Even with the sample the rad menu shows the items in single row instead of hierarchial manner. Please help me in this...

Grid disappears on itemclick

I have a RadGrid where each item has a NestedViewTemplate so that the user can click on a row and it will expand to show the details for that item. This was working fine for over a year, but recently I decided to update my controls to the current version (2009.1.527.35) and now, whenever I click on a row to expand it, then entire grid disappears and all I see is one horizontal line (could be the border?). I've tried debugging by putting a breakpoint in the ItemCommand method for that grid, but it never gets there. I have Ajaxified the grid, so I removed the Ajax to see if it was that, but it still does the same thing, even with a full postback.

This page happens to be the most complex page in my entire application. It includes a couple user controls and has code spread through several files including one Javascript file for client-side functions. So it would be difficult to reproduce this in a sample project. I did pull out the pertinent code and put it into a test page, but it worked fine in the test! I also removed the reference to the Javascript file, but it still does the same thing. If I had some idea of where to put a breakpoint, I'd be happy to debug it myself, but it doesn't seem to matter where I put it, it just doesn't touch the server-side code before it collapses into nothing...

UPDATE: Disregard, I just needed to add a NeedDataSource for the grid and everything's working now...

I have some problems to open the ToolTip ( many times closed before open completed if position right), my webservices are called many times generating overload of server and my style come so late generating one flash effect.

How to find the parent row of a nested grid's row on events

OK you may be confused by the title of the post, but I didn't really know how to express a good title for the post.

Here's what I have, I've got a nested grid in a grid and on events such as item_databound of the nested grid I need to find the parent row of the nested grid.

I've found a convoluted way in finding it, but I'm sure there's a simpler way, here's how I do it on the item_databound:

DirectCast(e.Item.Parent.Parent.Parent.Parent.Parent.Parent, Telerik.Web.UI.GridNestedViewItem).ParentItem

I have a similar convoluted way in getting this in a rowdrop event from the nested grid's

DirectCast(e.DragedItems(0).Parent.Parent.Parent.Parent.Parent.Parent, Telerik.Web.UI.GridNestedViewItem).ParentItem

Here's a quick example of what I'm doing:

    
            Public Sub rdgInvoices_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) 'Handles rdgInvoices.ItemDataBound  
        
                    Static Total As Double  
        
                    If TypeOf e.Item Is Telerik.Web.UI.GridDataItem Then  
        
            (e.Item.Parent, "TelerikForAjax")  
        
                        Dim gdiParent As Telerik.Web.UI.GridDataItem = DirectCast(e.Item.Parent.Parent.Parent.Parent.Parent.Parent, Telerik.Web.UI.GridNestedViewItem).ParentItem  
        
                        If DirectCast(gdiParent.FindControl("lblDirectExpense"), Label).Text = "1" OrElse DirectCast(e.Item.FindControl("lblDirectExpense"), Label).Text = "1" Then  
        
                            With e.Item  
        
                                DirectCast(.FindControl("lblInvoice"), Label).Visible = False 
        
                                With DirectCast(.FindControl("txtInvoice"), TextBox)  
        
                                    .Visible = True 
        
                                    ' ''On Error Resume Next  
        
                                    ' ''.Attributes.Remove("updateDE")  
        
                                    ' ''On Error GoTo 0  
        
                                    ' ''.Attributes.Add("onChange", "updateDE('" & directcast(e.Item.FindControl("txtInvoice"), Label).ClientID & "', '" & & "')")  
        
                                End With  
        
                                Dim rdg As Telerik.Web.UI.GridDataItem = ParentRow(e.Item.Parent, "TelerikForAjax")  
        
                                With DirectCast(.FindControl("txtAmount"), TextBox)  
        
                                    .Attributes.Add("onChange", "updateDE('" & DirectCast(e.Item.FindControl("lblAmount"), Label).ClientID & "','" & DirectCast(.FindControl("txtAmount"), TextBox).ClientID & "', '" & DirectCast(rdgCategoryBudget.Items(CurrentCategoryRow).FindControl("txtReconciled"), TextBox).ClientID & "', '" & DirectCast(rdg.FindControl("txtReconciled"), TextBox).ClientID & "', '" & DirectCast(rdgCategoryBudget.Items(CurrentCategoryRow).FindControl("lblSavings"), Label).ClientID & "', '" & DirectCast(rdgCategoryBudget.Items(CurrentCategoryRow).FindControl("lblTotal"), Label).ClientID & "')")  
        
                                    .ReadOnly = Not AllowReconciliation  
        
                                End With  
        
                            End With  
        
                  End If  
        
            End Sub

AjaxLoadingPanel doesn't go away

I'm using a RadGrid inside a RadAjaxManager that has its LoadingPanelID="LoadingPanel1". This is on a page that is part of master page setup, but is NOT the master page.

The master page is the page where the loading panel is defined, as follows:

    
            <telerik:RadAjaxLoadingPanel ID="LoadingPanel1" runat="server" Transparency="75" 
        
                    MinDisplayTime="500" BackColor="#E0E0E0">  
        
                    <img src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading6.gif") %>' 
        
                        alt="Loading..." style="border: 0; margin-top: 40px;" /> 
        
                </telerik:RadAjaxLoadingPanel>

This control works great nearly all the time except when using the filtering options on said grid. What happens, is that sometimes, not all the time, when you specify a filter on a column, the Loadingpanel comes up fine, the grid filter results are shown, and control is returned to the browser, however, the loading panel never goes away. It happens I'd say about 1 in 5 times, the other times its fine.

Am I using the panel wrong, or is there some known issue? I'm using 2008Q3 version of the controls.

Thanks,
Marty
