I have a radgrid and the datasource for it is a table consisting of 10,000 rows.  When I try to export this file to excel using the RadGrid ExportToExcel() method I get a system out of memory error.  Is there anyway to prevent this from happening.

Hi:

I have a rad editor in a user control, the user control inside of an Update Panel on a Jquery UI Dialog, but when I call the ExportToPdf method nothing happens and the Content of the rad editor goes away. When I remove the Juery Dialog and the Update Panel the Export Facility works as expected.

Any Sugestions?

Thanks in advance.

My Code is as follows:

Hello,
I have 2 list boxes and I have this below code that runs when an item from "RadListBox2" is moved to "RadListBox1". 

It executes and sorts fine after using the buttons to transfer items, however, if I drag/drop then there is an issue.  After dropping on "RadListBox1", it takes the item from "RadListBox2" and puts it in its proper place (meaning alphabetically sorted).  However, it also takes the very last item in "RadListBox1" and moves it up to the location where the item was dropped. 

 

public void RadListBox1_Transferred(object sender, RadListBoxTransferredEventArgs e)

 

 

{

 

RadListBox1.Sort =

RadListBoxSort.Ascending;

 

 

RadListBox1.SortItems();

 

}

So, just an example...
I start with ListBox #1 having values:  a, b, c, x, y, z
Then I drop value "m" from ListBox#2 onto ListBox #1 (location between "a" and "b")and I end up with this list: a, z, b, c, m, x, y  
The location of "m" is fine (it got sorted).  The new location of "z" is the problem.

Has anyone seen this behavior before?

Thanks,
Matt

When the user clicks on a treeview item checkbox, the following method is called. However, the page is refreshed and the treeview focus is lost. How can I stay with the currently selected item? Thx.

 

protected void rTree_NodeCheck(object sender, RadTreeNodeEventArgs e)

 

 

{

 

  hdnCurrentNode.Value = e.Node.Text;

 

  e.Node.ExpandChildNodes();

 

 

 

  if (0 == e.Node.Level)

 

    {

    e.Node.Nodes[i].Checked = e.Node.Checked;

    }

}

I tried this code as well:

 

 

//RadTreeNode rtn = this.rTree.FindNodeByText(hdnCurrentNode.Value, true);

 

 

 

 

 

 

 

 

//rtn.Selected = true;

 

 

 

 

 

 

 

 

 

//rtn.Focus();

 

 

 

 

 

 

 

 

 

//rtn.Visible = true;

 

But didn't help either.

It was working, then I came in today and it quit working.  I am probably using it wrong, but I'm not sure.  I've tried changing several different attributes, but nothing seems to work.  The only weird thing to note about this page is that it is a Child Page for a Master Page.  The Master Page has RadSplitters and Panes.  The Middle Pane is where the Content goes for the Child Pages...Below is my HTML for my Page with the RadWindow that won't open.  The Page refreshes like it wants to open the Window, but it doesn't...

Help?/Thanks

Hello,

I am writing an application in which I want to browse a default UNC path (and subdirectories) to select a file, at which point the file path and name would reside in the text box  (standard text box and button to browse for a file).  I want the allowed file extensions that may be viewed to be CSV,TXT and do not want the user to see any other extensions when browsing for a file.

I do not need to actually upload the file, as my process would be to take the contents of the text box containing the file path and name and store that info into a table (there is a back-end process that will pick up the file and load it).

I am not sure which control to use (asyncupload, upload, or filelocation) since I only need to select the file.

Is there an example of something like what I am attempting to do and a recommendation for the type of control?

Thanks,

         Please help me on same.

I seem to be having issues with the advanced form on the radscheduler causing the page to freeze when the save or cancel buttons are clicked.  The advanced form does not close, and the ajax loading panel displays the updating graphic, but the scheduler does not update.

This issue seems to occur consistently with all attempts to use the scheduler.  I first tried to adapt the Outlook scheduler example, and then tried again this morning with a basic scheduler scenario and encountered the same issue.

The examples work fine when run on my local machine, so could it be some server configuration issue with our production server that might be causing this?

The production server is a Windows 2003 / IIS 6 setup.

in the Editor, click on the Image Manager tool, then click "Upload",
uncheck "Overwrite if file exists?".
If I upload three existing files, I get an alert dialog with three times of "A file with a name same as the target already exists!".

Is there a way to only display one error message "A file with a name same as the target already exists!"?

I found a post and it seems like the solution doesn't work for me or maybe I miss something.

I'm using custom control which inherited from RadEditor.
I tried to add the following code in the custom control, but rfe is always null.

protected override void EnsureChildControls()
......
Telerik.Web.UI.RadFileExplorer rfe =
                (Telerik.Web.UI.RadFileExplorer)this.FindRadControl(this.Page);
            if (rfe != null)
            {
                rfe.ItemCommand += new RadFileExplorerEventHandler(radFileExplorer_ItemCommand);
            }
}

private Control FindRadControl(Control parent)
        {
            foreach (Control c in parent.Controls)
            {
                if (c is Telerik.Web.UI.RadFileExplorer) return c;
                if (c.Controls.Count > 0)
                {
                    Control sub = FindRadControl(c);
                    if (sub != null) return sub;
                }
            }
            return null;
        }

protected void radFileExplorer_ItemCommand(object sender, RadFileExplorerEventArgs e)
        {
            switch (e.Command)
            { 
                case "UploadFile":
                    //should I check the existence here?
                    break;
                default:
                    break;
            }
        }

Hi,

I have an autocomplete combobox within a radgrid. The combobox is fed directly from a Web service. When I move this combobox outside the grid it works fine. Is there some issue with having AJAX fed controls inside a grid?
