UseStaticHeaders causes header problem

When UseStaticHeaders=true and AllowScroll=true and there is not enough data to cause the scroll bar to appear, the Header does not render properly where the scroll bar will be. part of the header is not as tall as the rest.

This can be roughly corrected by setting the column widths, but when the grid is resized (due to moving splitter bars), the inconsistancy will show.
See attached

Using Skin="Office2007", but this appears to happen with all skins.

How can this be corrected?

RadDatePicker in Collapsible Panel

I am having issues with a collapsible panel I'm using which contains the RadDatePicker. It works fine in IE7 forward but in compatibility mode or IE6 the date input and calendar button do not reside inside of the collapsible panel. I have tried changing the ZIndex property on the RadDatePicker with the same results. I can add a z-index style setting to the date input or calendar element and it will place the particular element behind the panel but not inside. Any ideas on how to fix this?

RadTextbox to restrict special characters

Hi

I have a requirement to restrict a user from entering special character in the Radtextbox. I have tried both RegularExpressionValidator and CustomValidator with ClientValidationFunction, but both are capturing after user completes the entry. Just curious to know if we have any control just like AjaxTextbox extender so user will not be able to enter invalid characters instead of validating after the data entry.

Thanks

Upload file in ItemCommand does not overwrite existing file

Hi,
I am using an RadAsyncUpload inside my grid, to upload a single file. When in edit mode, the existing file is supposed to be overwritten. But this is not the case. I have tried with several different ways to create the file (my example here is the last one) - I have also tried using File.WriteAllBytes. This is my code:
In create mode, the file is created perfectly...

Control asyncUpload1 = editableItem.EditManager.GetColumnEditor("FileNameWithExtension").ContainerControl.FindControl("AsyncUpload1");

if (asyncUpload1 != null && asyncUpload1 is RadAsyncUpload)

{

if (((RadAsyncUpload)asyncUpload1).UploadedFiles.Count > 0)

{

UploadedFile uploadedFile = ((RadAsyncUpload)asyncUpload1).UploadedFiles[0];

if (letterTemplate.FileNameWithExtension != uploadedFile.FileName && letterTemplate.FileNameWithExtension != null)

{

File.Delete(GetTemplatePath(letterTemplate.MunicipalityCode, letterTemplate.FileNameWithExtension));

}

letterTemplate.FileNameWithExtension = uploadedFile.FileName;

byte[] buffer = new byte[uploadedFile.InputStream.Length + 1];

uploadedFile.InputStream.Read(buffer, 0, buffer.Length);

CreateDirectoryIfNotExistent(Server.MapPath(string.Format(TEMPLATE_PATH, letterTemplate.MunicipalityCode)));

using (FileStream stream = new FileStream(GetTemplatePath(letterTemplate.MunicipalityCode, letterTemplate.FileNameWithExtension), FileMode.Create))

{

stream.Write(buffer, 0, buffer.Length);

}

else if (e.CommandName == CMD_CREATE)

{

Label error = (Label)editableItem.EditManager.GetColumnEditor("FileNameWithExtension").ContainerControl.FindControl("lblError");

error.Text = "Angiv en Word skabelon-fil.";

return;

}

<b> Description: </b

>Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted.  This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack.  To allow pages to override application request validation settings, set the requestValidationMode attribute in the httpRuntime configuration section to requestValidationMode="2.0". Example: <

httpRuntime requestValidationMode="2.0"

/>. After setting this value, you can then disable request validation by setting validateRequest="false" in the Page directive or in the <

pages

> configuration section.  However, it is strongly recommended that your application explicitly check all inputs in this case.  For more information, see http://go.microsoft.com/fwlink/?LinkId=153133.

Grid RowDrop fires twice

I have a RadGrid control on a page where users can reorder projects by dragging and dropping. In a stand alone version it works fine, but once placed inside the ASP content frame in the existing site, the RowDrop event fires twice. If I step through and stop the second pass through the method, the rows reorder nicely. Is there a way to cancel the event from codebehind? Do you have any suggestions about what to look for?

BTW, this control is inside an ASP content tag within a master page. The majority of the code is directly from the samples in the 2012 Q1 release samples.

Thanks in advance
