On rare occasion I have seen the animated GIF that I am using in my loading panel get left on the screen, and does not go away unless I reload the entire page. Does anyone know if this is caused by something I am doing, or is just a bug / glitch? My timing parameters are:

InitialDelayTime

="0"

MinDisplayTime="500"

Thanks,
Peter

Combo box loosing selectedItem

I have multiple comboboxes and a "Add button" next to each combo box. User can type search term, select value and click on "Add button" for next step.

Combo1 - Add Button1
Combo2 - Add Button3
Combo3 - Add Button3

When user types search term in combo1 and selects a value and does not click on Button1 and goto 2nd drop down and search select and click on 2nd add button. Then click on 1st Add button, Combo1 looses its selected value i.e. get_selectedItem returns null.

Is it possibe for combo1 to retain its value?

Thanks

Insert not working!

Here is what I gave. Can you please direct me to a article that will help me.

Scenario:
Have 3 different layers. (DAL, BLL and UI)
Using objectdatesource at UI layer.
RadGrid's datasource is assigned at design time.
Able to edit data using WebuserControl.
added "add new record" at commanditem to insert.
But it's not doing anything.

No form or user control is showing up. Can you tell me what am I missing. How to tie this event to show the usercontrol in insert mode or something.

I read the topic where in usercontrol has been used. But got an error in :

<asp:button id="btnUpdate" text="Update" runat="server" CommandName="Update" Visible='<%# !(DataItem is Telerik.Web.UI.GridInsertionObject) %>'></asp:button>

            <asp:button id="btnInsert" text="Insert" runat="server" CommandName="PerformInsert" Visible='<%# DataItem is Telerik.Web.UI.GridInsertionObject %>'></asp:button>

Help will be greatly appreciated.

[Solved] Cannot get loading panel to display

I am trying to get a loading panel to display during AJAX postbacks. I have a RadGrid inside an Update Panel. The help states "In order to have a LoadingPanel, you need to drag it to your web form from the toolbox just like any control. Then you can set a control to use a LoadingPanel using the design-time." However, is does not explain how to "set a control to use a LoadingPanel." Please point me to the documentation for doing this (I have been digging for a while but cannot find it.)

Thanks,
Peter

Large # of XAxis Items

I have a chart which is going to show an area chart with one point for each day over a 6 month period. I only want to show an X axis item for each month of the 6 month period. I tried just adding an Item for each new month (ex. RadChart1.PlotArea.XAxis.AddItem("Name of Month")) but then the other set of data doesn't show up (eg. the chart is empty).

If I add one item for every item in my series (one for every day) I end up with a completely unreadable mess at the bottom of the chart. Instead, I tried added a new item, but setting it's text to empty, ex. RadChart1.PlotArea.XAxis.AddItem(""). That is also unreadable - it fills in the empty values with 0.

Here's what the code basically looks like:

    
            this.radRollingChart.AutoLayout = true; 
        
            this.radRollingChart.AutoTextWrap = true; 
        
            Telerik.Charting.ChartSeries peopleSeries = new Telerik.Charting.ChartSeries("People", Telerik.Charting.ChartSeriesType.Area);                       
        
            this.radRollingChart.Series.Add(peopleSeries); 
        
            peopleSeries.PlotArea.XAxis.AutoScale = false; 
        
            int currentMonth = 0; 
        
            foreach (DataRow row in traffic.Rows) 
        
            { 
        
                DateTime ddate = (DateTime)row["ddate"]; 
        
                if (ddate.Month != currentMonth) 
        
                { 
        
                    string date = ddate.ToString("MMM dd yyyy"); 
        
                    this.radRollingChart.PlotArea.XAxis.AddItem(date); 
        
                    currentMonth = ddate.Month; 
        
                } 
        
                else 
        
                    this.radRollingChart.PlotArea.XAxis.AddItem(""); 
        
                peopleSeries.AddItem((int)row["Count"]); 
        
            }

Any thoughts on how I can do this?

Also, is there a way to shut off the value that appears at the top of each data point in the chart (above each "bar")?

Binding to two tables.....

I'm binding an Rad menu to two data tables. The code below is working but I can't get rid of the root node generated by the code. Any ideas?, Or is there a better approach?

Return XML ..

    
            public static string GetMenuItemsFromSQL()  
        
                {  
        
                    string xml = string.Empty;  
        
                    string queryString = @"SELECT Department.Name AS name, Department.DepartmentID AS id,  
        
                                           Department.Description AS desription, Category.Name AS name,   
        
                                           Category.CategoryID AS id

NestedViewTemplate with Repeater

I am binding a RadGrid to a collection of standard business objects and using the NestedViewTemplate to display more information about each item. On each object that is part of the grid there is a sub-collection of items that I am wanting to bind to a repeater that is inside my NestedViewTemplate. I tried using the ItemCreated event handler and my repeater is successfully found, but my GridItemEventArgs.Item.DataItem is null so it can't bind it. Is there a way to do this?
