I often use image with Telerik controls such MenuItem, buttons, ect. via the Image property or BackgroundImage property.

Do I need to dispose of these images myself?

Thanks,

[Solved] Application Exception

Hi,

First of all I hope I'm posting this in the right place.

I have just finished building my first application, published it and have now (as best as I can tell) installed it on a couple of machines.

Unfortunately when the users are trying to add a row on a gridview they are getting the following error message.

System.InvalidOperationException: Items cannot be added to the RadListSource when is in data-bound mode

I have no idea what this is or how to resolve it. I've tried various searches with little results. The application works perfectly when I'm in design mode but I too get the same error so I think I have ruled out any DotNet issues.

I'm really hoping someone here can help.

Kind regards,

Guy

[Solved] Closing Pop up Radwindow

Hi,

I have a button(addproduct) on my Product.aspx page and when I click on that button I get a pop up window(radwindow) whose url points to some other page(productsearch.aspx) which has a cancel and save button. Now, What I need to do is, when I click the cancel button, the popup window should close and I should be back on the product page without losing whatever data I already have in the product.aspx page.
I need to do this on the client side so I have to use javascript. The code which I have for the window popup is

function openWin(){
var oWnd = radopen("../product/Productsearch.aspx","productsearchwindow");
return false;
}

the productsearchwindow is the id of the radwindow and I call the openWind() function on the onclientlclick event of the addproduct button on product.aspx page

I probably have to write some javascript in the productsearch.aspx page as the save button is in that page and the popup url points to this productsearch page.

Can anyone help me in writing the js code.

Thank You,
Vik

Calling code in SelectedNodeChanging does not hightlight selected node.

We have a scenario where, a user will select a Treeview node in which we perform logic within the SelectedNodeChanging event. Using e.Node we are able to validate that the node being selected is the correct node. However after performing logic in using the SelectedNodeChanging event, the newly selected node does not show as highlighted in the treeview.

We have validated that the clicked node is in fact the selected node in the treeview, however it simply does not show it as selected by being highlighted.

Are we missing something? Is there something else that we have initialize or call to show the node (e.node) highlighted?

[Solved] Turning on the Horizontal Scroll bar

Hi -

I understand from reading other threads that the automatic horizontal scroll bar feature does not work if the grid is set to column fill.

Is there a way to manually turn on the horizontal scroll bar?

I would like column fill on for the case when the user resizes the form larger. But if the user resizes the form smaller, I need a scroll bar so that the user can see all of the columns.

Any tips would be appreciated.

Thanks!

[Solved] RowFormatting bug

I followed some threads here about using Row.Tag to keep track of newly added rows and changed rows via RowFormatting event. It is something like this:

private void gridView_RowFormatting(object sender, RowFormattingEventArgs e)

{

if (e.RowElement.RowInfo.Tag != null)

{

if (e.RowElement.RowInfo.Tag.ToString() == "NEW")

e.RowElement.ForeColor = Color.Green;

else

e.RowElement.ForeColor = Color.Red; //Changed

}

Let say I updated one row. The row is now colored in red color. When I scroll down the grid using the scroll bar, I noticed that there are more red colored rows appeared while I was scrolling down. If I stopped it quickly enough, an incorrectly red colored row would show up inside the grid's view port.

Look like somebody forgot to clear out the RowInfo information :)!

Resize pages in Pageview

Hi,

Is it possible for an end-user to vertically resize individual pages in a PageViewPage, with ViewMode set to ExplorerBar? Right now, when a page is expanded, it's content has a fixed size.
