Hello, 

Hi Telerik,

When I disable radcombobox with javascript, it is still possible to change items.

Here are some steps to reproduce this behavior.

http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/multiplecomboboxes/defaultcs.aspx
On the above link, when I execute the following javascript (with firebug):
$find("RadComboBox1").set_enabled(false)
The combo is disabled, but when i focus the input element and start to type, the items change.

Is this a bug or is there another function which should be called?

I got firefox 9.0.1

Hi,

               Now  I am using sharepoint 2010 for my project. I want to configure a web application for using telerik controls. What are the steps i have to follow to configure the web application.

Thanks.

Hi,

I am using nested radgrid in which I have at the top is Quotations then Groups and then Items. I want to calculate the total cost of Items in each group but the problem is that whenever I rebind a radgrid after adding a new Item it's giving me the following the exception. The purpose of rebinding is that I want to display a total in lblTotalCost in an itemdatabound event, and if I don't do rebind then it doesn't give me any exception.

Any help would be greatly appreciated.

Thanks.

Exception : DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'ItemName'.

can you please help me ?

I have a page with an edit form on it and this has some RadTextBox and RadNumericTextBox controls. The page uses a master page that has a RadFormDecorator declared on it and is set to decorate Textbox controls. RadTextBox controls are set to a width of 300px.
The problem i have noticed is that when the page loads and i click a button to show me a edit form (the edit form is set to visible = true) all the RadTextBox controls have a width set to 294px but when i hover over a control its width is resets to 300px. All this makes the form look bad because every time the user hovers over any of the RadTextBox controls it changes its size and changes the look of the form.
All this only hapend if the page uses AJAX to update controls.

If i include an ASP Textbox control on the page an set its width in markup to 300px it renders as 294px when i open my form but it doesn't suffer from the same resizing on hover as the RadTextBox does.

If i change the RadFormDecorator not to decorate Textbox controls the problem goes away and all the TextBox controls are rendered with a width of 300px.
As said the problem appeared when upgrading to Q3 2011 release. If i go back to using Q2 2011 release the problem goes away.

Hi,

I WANT

Name  type blck  01  02   03      04.  ... as    HEADERS

I have 2 combo boxes with treeviews in them for a States drop down list and when I click a button, I would like the first combobox to copy the value and text to the second one as well as select the appropriate node and expand to it if needed. The combo box is a list of states and then the only parent is Territories which then shows the US territories. The code I have is as follows.

My markup is as follows...


Then code behind is...


I'm having 2 problems... 1 is when i click the button the first time it'll get the text and value from the combo box but on the second time around it's null. 2 is I can't get the second state combobox to set the text and value and the selected item value.

Hi,

Could you please let me know any sample code or demo Cascading RadComboBoxes with Load on Demand. I would like to load both RadComboBoxes using WCF service.

Thank you..
