Hi,

I am using radgrid for my application. In my application, I have changed the column position by drag-drop in runtime.

After refreshing the page or radgrid, the column was changed to its old position.

How to maintain its state?.

Please give any suggestions.

Thanks in advance.

Mahali

hello ,

I want a new tab also in the hyperlink manager dialog box just like initially we have a option of "anchor Tab", "hyperlink Tab" , "Email tab" so I also want a "telephone tab" link also in the dialog box so please help me from where i do that customization in that .

I ran into an issue where an FTP user could not access files uploaded from a radasyncupload control.  The user had permissions to the target directory.  Files added to the directory inherited the permissions of the directory when except when uploaded asynchronously. 

Here’s what I found.  In a part of my application I’m Telerik RadFileUpload instead of the standard asp file upload control. 

Because Telerik RadFileupload is asynchronous, it first uploads the file to a temporary directory (/RadUploadTemp).  Once fully
uploaded, it then automatically moves it to the target directory (/TargetDirectory/…)
 
Here is the problem.  As the file is being moved it takes the permissions associated the temporary directory with it. Since the fpt account had no permissions in the RadUploadTemp directory, it assigns no permissions to the file when moved to the TargetDirectory .

In order to resolve this, I gave read permissions the ftp account in the RadUploadTemp directory and now it copies the files with the permissions.

While the link below does not address the rad control specifically, it lead me to the answer.  In my case, I had to apply permissions to the temp directory.

http://stackoverflow.com/questions/23136723/why-are-permissions-wonky-when-my-iis-worker-saves-a-file-in-asp-net

Is this something Tererik could fix in a way similarly stated in the article?:

"I suspect the problem is with the use of Path.GetTempFileName followed by File.Move. When the uploaded file is saved to tempFilename, the temporary file gets whatever permissions are assigned to the temporary folder. Moving the file preserves those permissions as is instead of recalculating the inheritable permissions based on the destination.Instead of File.Move, try using File.Copy"

Hope this helps somebody else. 

I hope you can help me

how I can insert a selected row of a RadGrid on another RadGrid using JavaScript

I have many problems understanding JavaScript, since I'm new to JavaScript programming

Thank you for your help

I am having issues with Resource text not getting displayed while taking the Export to Pdf option. I have attached screenshots of what is being rendered on the page (Scheduler.JPG) and what gets printed to pdf (Scheduler PDF.JPG) when I do "RadScheduler1.ExportToPdf();" from code-behind.
 I tried adding this 
<ResourceStyles>
  <telerik:ResourceStyleMapping ApplyCssClass="radResourceWidth" />
</ResourceStyles>

And in css : 
.radResourceWidth
        {
            width:150px;
        }

It still is not working. 

Please help !!

Hi 
I have a Turkish character problem in c# Radeditor pdf export. I use "Arial Unicode MS" font. Characters like ı-ş-Ş-ğ-Ğ-İ don't be a problem in editor Desing or Html , but after exporting to pdf these characters are displayed as "#". I think the reason is that Azure server i published doesn't have this font.
I cannot install any fonts to the server. How can I solve this problem?
The telerik version I use is q2 2014.

Hi,

I consider myself as newbie in Telerik. I am trying to bind RADHtmlChart to SQLDatasource and it works in other project except this specific one. Hope someone can point out the issue. If I load the same data in ASP Datagrid I can see it on my page. However both RadGrid and RadHTMLChart doesn't work. One more thing, the normal RadChart works fine with same data source.

ASPX Code
SQL DataSource
