Hi, My requirement is to display the button in the Grid.So in the cellformatting i have added the below code to display button in the cell of the Grid.

RadButtonElement

 

 

radButtonElement = new RadButtonElement();

 

radButtonElement .Click +=

 

new EventHandler(radButtonElement _Click);

 

e.CellElement.Children.Add(radButtonElement );

The problem i am facing is when the Grid is getting filled it is displaying the Button in the Grid.But when i click on it for the first time it is not firing the radButtonElement _Click event. When i click second time it is firing.

Could you suggest me how to fire the click element for the first time only.

Hi,

      Is there any option for binding data for  Rad Multi Column combo box  on demand ( like Load on demand in web application ).
 I want to Implemented this option in my Rad form.

In the GroupSummaryEvaluate event, I want to loop through the data rows in the group looking for a row based on some criteria against the data in that row.  I then want to display some data from this row in the group description.  I can do this using e.Group.Rows.  However, the Rows property is marked as deprecated and the Items property is not accessible.  What is the best way to do this?

Hi!
Im using RadRichTextBox v1219 and i would like that hyperlinks clicked just be exibited in my application browser, prevents any external action. I can get HyperlinkClicked Event and direct the URL to my browser, but the hyperlink opens an external browser too and i dont want to, there's any way to cancel the event? Thanks!

Hello.

I have Gridview with ColorColumn which is binded to database varchar field. Data displays correctly, but when I want  to change it, error [Input string was not in correct format.] is thrown. I think it has something to do with changing data from string to System.Drawing.Color.

Regards.

I just want to make sure I'm doing this correctly.  In my constructor I have this:
            HamsGrid.MasterTemplate.SortComparer = new HamsCustomComparer();
            HamsGrid.MasterTemplate.SortComparer = null; //line 1807 in code
Setting it to null is causing an exception (I only have from my call at line 1807 on up):
System.NullReferenceException: Object reference not set to an instance of an object.

Hi,

I want to use a RadListView in Icons View Type showing long label.
Here is the code :


The problem is when the list size is to small, a scroll bar appears, but an empty space appears too on the top of the list, and the last item of the list becomes hidden (even in scrolling down the list)

The first image shows the list with all items, the second one has too little width (and an empty space on the top), the third shows the list with an invisible item

Could you help me with this?
Thanks

Regards,

Hello,

I'm totally new to creating charts with Telerik's controls. What I need to create is a gantt chart that will display employee names on the Y-Axis and a time range on the x-axis.

So basically my data would come in the form of this:

John Doe - Worked from: 11:00, to: 17:00
Martha S. - Worked from: 5:00 to 11:00

So, the names would appear at the vertical plane, while a time range would be at the horizontal plane.

Help please!

I know I should've searched, but since i'm really new to this, I wouldn't exactly know what to look for.

Thanks in advance guys.

Hi there,
    I have a datatable that I am using as the source of my datagrid. The datagrid is a self referencing hierarchy. When I add a row to the datatable, it does not appear in the grid. If I add a second row, or click around in the grid it appears. It is as though the grid is not being repainted. I need to mention that this grid allows for drag and drop from another grid.

Code under my add button:

nCount += 1

 

Dim dr As DataRow

 

dr = dtTable2.NewRow

dr("Item Number") = nCount
dr("ParentItem") = 0

dr("Item Desc") = ""

dr("Quantity") = 0

dr("UOM") = ""

dr("Vendor") = ""

 

dtTable2.Rows.Add(dr)

 

dgBOM.DataSource = dtTable2
