I have a RadGrid (v2009.2.701.35) using the Web20 theme. In my attached screen shot, the grid in the upper half is the grid with the default horizontal text in the header. Notice the uniform borders between all of the header columns. The grid in the lower half is a result of changing the header text to render vertically. Now notice the difference in column widths between columns 1 & 2 vs columns 2 & 3 or 3 & 4. Is there any way to get uniform header column borders with vertical header text? Here's my CSS tweak w/ changes in bold:

.RadGrid_Web20 .rgHeader, .RadGrid_Web20 .rgHeader a

{

color: #ffffff !important;

font-family: Arial !important;

font-size: 8pt !important;

font-weight: bold !important;

text-decoration: none;

text-align: left;

border-color: #FFFFFF !important;

writing-mode: tb-rl !important;

filter: flipV flipH !important;

}

"RadEditor - please enable JavaScript to use the rich text editor" message in RadEditor

Hi,

I'm experiencing a weird issue in radeditor (v2010.2.826.35) in my aspx pages. Following message appears just under the editor in preview mode:
RadEditor - please enable JavaScript to use the rich text editor

I checked and find that some <noscript> tag gets added to the editor which displays this message.

I tried removing it, but failed.

Can you please suggest on why this is happening and how to get rid of it?

Error combining CheckBoxes, AutoPostBack and EnableVirtualScrolling

I have this ASPX code:

<telerik:RadComboBox runat="server" ID="instituicao" Width="450" CheckBoxes="true"

AutoPostBack="true" ItemsPerRequest="10"

EnableLoadOnDemand="True" ShowMoreResultsBox="true" EnableVirtualScrolling="true"

OnItemChecked="instituicao_ItemChecked" OnItemsRequested="instituicao_ItemsRequested" />

And this code behind:

protected void instituicao_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)

{

DataTable dt = GetData();

int total = dt.Rows.Count;

int itemOffset = e.NumberOfItems;

int endOffset = Math.Min(itemOffset + instituicao.ItemsPerRequest, total);

e.EndOfItems = endOffset == total;

instituicao.Items.AddRange(

dt.Rows.OfType<DataRow>().Skip(itemOffset).Take(endOffset - itemOffset)

.Select(i => new RadComboBoxItem(i["Id"] as string, i["Id"] as string)));

}

protected void instituicao_ItemChecked(object sender, RadComboBoxItemEventArgs e)

{

// do stuff

}

private DataTable GetData()

{

DataTable dt = new DataTable();

dt.Columns.Add("Id", typeof(string));

for (int i = 1; i <= 100; i++ )

{

DataRow row = dt.NewRow();

row["Id"] = i;

dt.Rows.Add(row);

}

return dt;

}

When I check an item I got this error and my code is never executed:

[ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

Parameter name: index]

System.Collections.ArrayList.get_Item(Int32 index) +7487944

Any clues?

Problem with editor menus when scrolling Firefox

We're having a problem accessing context and toolbar menus in the Editor using Firefox when the browser page has been scrolled. No problem with IE.

I'll include a link to a short video demonstrating the problem. You'll see that once the browser has been scrolled, the context and toolbar menus appear in different positions, and clicking an item on the menu has no effect; the menu disappears on mousedown. Once the browser page is scrolled back to the default position, the menus become functional again.

The problem seems to have manifest after upgrading the site to .NET 4.0.

The version of Telerik.Web.UI.dll is 2009.2.701.20. I realize this is not the current version of the editor and upgrading is in our near future, however, this problem has to be resolved immediately. Any help would be appreciated.
