Questions on UI for ASP.NET AJAX Forum

I have three radgrids on one aspx page.

If you click on a row in RadGrid1 it will update the results in Radgrid2, and if you click on a row in Radgrid2 it will update the results in Radgrid3.

In RadGrid3 I have a GridTemplateColumn with an ImageButton that opens a new page using the RadWindowManager. This works great and the window opens, but only for the first row in RadGrid3. If I click on any other row I get the following JavaScript error.

Get_masterTableView(0.get_dataItems()[…] is null or not an object.

I have used the same code for other pages and it works flawlessly. The only difference here is I am using multiple grids vs. one grid on the page.

I think since RadGrid1 had only one row the RadWindowManager is pointing to it, I need the RadWindowManager to use the results from RadGrid3

Code for WindowManager and AjaxManager

Export to Excel - exports dataset as well as grid

    
            DataSet dsAdminEventInvites = new DataSet();  
        
            EventInvite.GetEventInvites(databaseName, eventID, ref dsAdminEventInvites, ref errorMsg);  
        
            rgInvitesExport.DataSource = dsAdminEventInvites;  
        
            rgInvitesExport.DataBind();  
        
            rgInvitesExport.ExportSettings.OpenInNewWindow = true;  
        
            rgInvitesExport.ExportSettings.ExportOnlyData = true;  
        
            rgInvitesExport.ExportSettings.IgnorePaging = true;

[Solved] RadMenu Image Preload

Hi,

I was experimenting with the samples of RadMenu and was testing the sample in which the menu items are made of only images. What I noticed is that when I hover my mouse over various items, their onHover image gets loaded at that particular time which causes some delay before reflecting that the menu item has been selected. It is due to the time it takes to load the state images.

I would like to suggest could you please make the menu Preload images before the menu gets rendered on screen. That is the images of the states should not be loaded at the time of hovering, instead in the beginning of the page, and the various states should be reflected at the same time. This is annoying infact to have to wait until the item image loads, which can take some time based on the size of the file, and I feel that it takes away the professional touch.

Thank you.

Scheduler as Calendar

Hello,

I am planning to substitute the calendar in my website with the Scheduler control. Would it be possible to remove the "editing" function of the control (like a property that I need to toggle) when viewed by the public and have instead an admin page that has the edit control placed behind authenticated pages?
