Hello, I have a RadGrid with a pageSize = 10 and i used a Server Side Paging to retrieve my data. The problem is when the radgrid had the values startRowIndex = 10 and MaximumRows = 10 from the objectDatasource, it show just one record in the Page 2. In the other Pages it's ok. Here is my Code :

Programmatically set datasource of detail table

I have a 3 level hierarchical grid. I set the datasource of each child grid in the ASPX. I now have added a checkbox to include older data from the tables, and if that check box ix checked, I want to change the datasources of the master and detail tables. I have an oncheckboxchanged event handler for the checkbox, and can set the master grid datasource fine. What is the code to set the detail table's datasource in C# in the checkboxchanged event handler?

Thanks

    
              protected void outdatedChanged(object sender, EventArgs e) 
        
                { 
        
                    CheckBox cb = (CheckBox)sender; 
        
                    if (cb.Checked) 
        
                    { 
        
                        providersGrid.DataSourceID = "CCprovidersIncludingOutdated"; // master grid       
        
                     //I want to set the detail grids datasources here for outdated content 
        
                    } 
        
                    else 
        
                    { 
        
                        providersGrid.DataSourceID = "CCproviders"; // master grid 
        
                        //I want to set the detail grids datasources here 
        
                    } 
        
                }

Multiple AjaxRequest Events

I have a website that is structured as follows:

-> MasterPage - Contains RadAjaxManager control
     ->Page
          ->Control 1
          ->Control 2
          ->Control 3
          ->Control 4

Each control needs to implement a AjaxRequest event handlers for control specific events (nothing cross control, or master page stuff). So in each control I am using RadAjaxManager.GetCurrent(this.Page) method and attach to the AjaxRequest event. The problem I am having is that if the javascript from Control 1 fires the AjaxRequest event all of the other controls seem to get their event handlers called as well. Is there a way to filter the requests so they don't all fire? Is there a better way to do this?

RadMaskedTextBox multi-language

Greeting!

I was tryign to implement RadInput controls to form (due to large amount of simple validations specific for every control) and found that RadMaskedTextBox is made only for engl-lang developmens, while i need to implement Rus mask.

If there any possibilities or solutions to make it? Or mask will stay there with ASCII [page:0] only and no possible utf-8 implementations can be done?

Custom CSS are not working in Edit mode

Hi,
We have custom master pages which make use of custom CSS classes.
When authors go in edit mode the contents inside the RADEditor are displayed using its own CSS and it doesn't respect the custom css of the master page. Not even in the Preview mode.
But, once the page is published it uses the custom css classes.
We have tried config.xml and CSS settings but not able to make it work in Edit mode.

Thanks in advance.

[Solved] XAxis Date & Time

I have a datasource that includes an undetermined time range. Because of this I need to display both Date & Time in the xAxis labels. I have seen the various posts on including date or time but don't see how I would include both. In my own code I currently can toggle between showing date or time by simply toggling the ValueFormat as seen below. How can I show both?

    
            _chart.AutoLayout = true;  
        
            _chart.PlotArea.XAxis.IsZeroBased = false;  
        
            _chart.PlotArea.XAxis.Appearance.ValueFormat = ChartValueFormat.ShortTime;  
        
            _chart.PlotArea.XAxis.Appearance.LabelAppearance.RotationAngle = 320;

[Solved] Tooltip Not Showing on MouseOver - Same Code Works Elsewhere

I'm stumped. I have a column in a grid with an image. In one working page, on mouseover of the image we use the webservicesettings to call a service and dynamically value the mouseover tooltip with a larger thumbnail of the image. It works great and is based on the image gallery sample that auto-sizes and such.

I have another page that also has an image column and calls a different service to do the same effect. However when I mouse over the image NOTHING HAPPENS. I set an alert in the OnClientBeforeShow function and it never seems to be called. The only difference I can think of is that this page uses the code that does an OnPageLoad ajax request to show a loading graphic while the page loads. Is this perhaps causing issues with the radtooltips?

The only differences I can think of are 1) the initial ajax on page load addition, and 2) the additional asp panel wrapped around things that is not in the other screen which works fine.

Here is the master page aspx, the page aspx, and the page code-behind.

Thx!

Master page:

    
            <%@ Master Language="C#" AutoEventWireup="true" Codebehind="WebAppMaster.master.cs"
