Hello,

I have a RadComboBox that contains a RadTreeView. I am using the ItemTemplate to display the tree view. My question is, besides displaying the Tree View, I would also like to add a single item to the RadComboBox where Text = "All" and Value = "0". So, the RadComboBox would display "All" and the below that, it would display the RadTreeView.

Is this possible to do?

Thanks,
Dave

Which displays fine on first databind, but on rebinding with new data on this button press the old chart stays on screen?

    
            protected void searchButton_Click(object sender, EventArgs e)  
        
                {  
        
                    Report report = new Report();  
        
                    RadChart1.DataSource = report.RetrieveSSPhraseDailysp(keyword, 99, 1, fromRadDatePicker.SelectedDate, toRadDatePicker.SelectedDate);  
        
                    RadChart1.DataBind();  
        
                    phraseGridView.Rebind();  
        
                }

What am i doing wrong?

Thanks

Show sorting indicators, but not allow sorting

I am setting the sort order in the code behind (programatically) and I would like to have the sorting indicators displayed while not allowing the user the ability to change the sort order.

By setting the AllowSorting = true the indicators will show correctly, however, the user can then change the sort order.

RadMenu width is set eventhough the second row appears

Have a Radmenu with Items.

There are more than 10 RadMenuItems so it overflows and shows in the second line.

Then i used EnableRootItemScroll = "true" and width to 80%, Even though it shows in the second line but with the scroll.

I have attached the screen shot too.

I need to bring the all the items in a single line with scroll.

Thanking You

BING Maps control in ASP.Net page

Hi everyone,

a) Does anyone know if there are plans for an ASP.Net Ajax control for using BING Maps?

b) What's the proper way of integrating the Silverlight RadMap control in an ASP.Net page? I have users using browsers as old as IE6 (i know!!!) and I am concerned as to what they'll see if I host a Silverlight control in my page. Any ideas, suggestions, warnings? :-)

[Solved] RadGrid Span around Checkbox disabled

I have a grid that uses paging, frozen headers and autogenerated columns. My issue is when I click on the pager to get to the second row set all the checkboxes are disabled. These work fine on the first page view but then after I click on the any page they are all disabled. There is a <span disabled=disabled">checkbox</span> placed around them. Can't seem to figure out what is causing this.

Thanks

DbValue not working correctly?

Hi, if I'm reading the documentation correctly, when my page loads and I prefill the rating control from a database, I should be using something like this:

cboAnalystRating.DbValue = dbReader(

"analystRating")

The problem is that it's not actually setting anything. If I use this:

cboAnalystRating.Value = dbReader(

"analystRating")

Then it works, but I get the usual can't convert DBNull to another format message.

What am I missing here?

[Solved] Skin not applied on safari / chrome (radprogress)

When we use the radprogress for uploading file, we see the skin in IE, and in firefox (with some trouble with FF35, I think that they are now solved)... but in safari and chrome, we see the white progress without any skin.

This happened in our code, but also in the telerik demo page

http://demos.telerik.com/aspnet-ajax/upload/examples/customprogress/defaultcs.aspx

In this page, with the latest safari and chrome, we do not see the skin.

So if the official telerik demo have the bug, I suppose that this is not something we did not configure correctly on our side !

EditForm - textareas rather than textboxes

Hi. I'm using a RadGrid in a relatively default form, with AutoGenerateColumns="false" and EditMode="PopUp". The Edit form works great straight-out of the box, with the small exception of a textbox that I would like to make a textarea (multi-row textbox). Is there anyway to do this without going down the custom editform template route? Thanks, Chris

[Solved] Multiple filter clearing

Hi,
I've a RadGrid with one column filtered with a RadComboBox.
Following support examples, I've seen that to clear the RadComboBox filter I've to reset the RadGrid1.MasterTableView.FilterExpression and I've to reset the CurrentFilterValue of the interested column.
This solution works well if I've selected only one filter.
But, if I've other filters applied in other columns, resetting the FilterExpression cause the other filters to be resetted too.
The only solution I've found is to manually rebuild the filterExpression, parsing the string with a complicated regular expression.
Is this the right solution?

Greetings
Marco
