Hi all,

I am using 2011.2.712 version.
I usually (not always) get this error and I have tried to read many articles about the issue on this forum and the others but not successfully.
Here are my 2 scenario :
1. The first page has a RadGrid which is in a RadAjaxPanel. When I interact with its paging (the number, or icon Next, Pre, etc), this error usually appears. I mean it's not always.
2. The second page has a button which used to export data into a folder on hard disk with .csv extension. I have replaced Response.Close(); by HttpContext.Current.ApplicationInstance.CompleteRequest();. It's OK. But after finishing this action, this error appears.

I really don't know how to fix this issue.
Please let me know what is the problem and how can I solve it.

Thanks in advance,
Phuc

Hi,
I have a rad text box in a rad window. On page load i simply try to set focus on it using radajaxmanger. It runs successfully on all other browser except for firefox3.6. Focus gets onto the text box as soon as i click on the control. I tried so many ways to set focus on it(client side as well) but it didn't prove any fruitful result. Is it something related to browser behavior or i need to look onto controls. Please help asap.
Thanks in advance.

Hi,

I have a Rad grid on my page With fetures like, Column Resize, Filter, Sorting, Expand/Collapse , NestedViewTemplate etc enabled .
Everything is working fine except one scenario.

When I make a column resize first, and then if i try to sort any column, the grid width is Automatically expanding out of the box after the postback caused by sorting , What i can see here is when i resize one column in client side, the other column widths are automatically reduced to maintain the grid's width. But after the postback the other columns default widths what i set while design time are retained back and the expanded column maintains its new width, and hence the entire grid's width is expanding.

I tried with Resizing-ResizeGridOnColumnResize="false"/ setting fixxed width to grid etc. But no use
Need Help urgently.
Thanks

Hello!

Let's go straight to the problem.

I have two gridviews from which one generates the data source to another one. Both gridviews have ability to edit the item (row), but editing only works in first gridview (the one that generates data for the other one), when I click on edit in the second gridview nothing happens. I've been searching the web for a while and (I believe) found out that what I need is AJAX Manager.

I've checked couple of examples/Demos from Telerik's site, but I'm still not sure how to make editing in the second gridview work.

Both gridviews have edit forms inside and both gridview's edit form types are "WebUserControl".

Could someone help me out with some suggestions. Any help would be appreciated.

We are evaluating the Grid and will need to access the grid in an unbound fashion, adding, hiding rows, columns, etc as well as getting and setting the values of specific cells from both the client and/or server side at run time.

Is this possible?  Does anyone have a quick and easy sample of how to do this?

This is default page code:
protected void grdFiles_ItemCommand(object source, GridCommandEventArgs e)
    {
        if (e.CommandName == RadGrid.DownloadAttachmentCommandName)
        {
            
                GridDownloadAttachmentCommandEventArgs args = e as GridDownloadAttachmentCommandEventArgs;
                string fileName = args.FileName;
                int attachmentId = (int)args.AttachmentKeyValues["ProjectFileId"];
                ProTrakEntities objEntity = new ProTrakEntities();
                ProjectFile objFile = (from type in objEntity.ProjectFiles where type.ProjectFileId == attachmentId select type).First();
                string filename = objFile.FileName;
                string Filetype = objFile.FileType;
                byte[] binaryData = (byte[])objFile.FileData;
             
                Response.Clear();
                Response.ContentType = Filetype;
                Response.AddHeader("content-disposition", "attachment; filename=" + fileName);
                Response.BinaryWrite(binaryData);
                Response.End();
            
        }
    }

**Uploaded file Code**
 protected void DetailsView1_ItemInserting(object sender, DetailsViewInsertEventArgs e)
    {
        if (DetailsView1.CurrentMode == DetailsViewMode.Insert)
        {
            if (Session["ProjectId"] != null)
            {
                int Projectid = Convert.ToInt32(Session["ProjectId"]);
                string Description = (DetailsView1.FindControl("RadEditor1") as RadEditor).Content;
                RadAsyncUpload radAsyncUpload = DetailsView1.FindControl("RadAsyncUpload1") as RadAsyncUpload;
                UploadedFile file = radAsyncUpload.UploadedFiles[0];
                string s = file.FileName;
                string path = System.IO.Path.GetFileName(s);
                    string Contenttype = radAsyncUpload.UploadedFiles[0].ContentType;
                int fileSize = radAsyncUpload.UploadedFiles[0].ContentLength;
                float length = float.Parse(fileSize.ToString());
                byte[] fileData = new byte[file.InputStream.Length];
                file.InputStream.Read(fileData, 0, (int)file.InputStream.Length);
                        ProTrakEntities objEntity = new ProTrakEntities();
                        ProjectFile objFile = new ProjectFile();
                        objFile.ProjectId = Projectid;
                        objFile.FileName = s;
                        objFile.FileType = Contenttype;
                        objFile.FileSize = length;
                        objFile.CreatedBy = "admin";
                        objFile.CreatedDate = DateTime.Now;
                        objFile.Description = Description;
                        objFile.FileData = fileData;
                        objEntity.AddToProjectFiles(objFile);
                        objEntity.SaveChanges();
                
            }
         }
    }
I'm saving the data in database in binaryfromat.i data was not downloading from sever when i click the attachmentcolumn.

Hi,

I am trying to set the values for Between filter in the PreRender event of the grid..
Filter works fine if I  pass a single value (int)
But I need to pass a range of values and use "Between" filter. Tried couple of syntaxes given below but did not work. Can you please let me know what am I doing wrong?

 

Hello guys,

I'm facing a problem with the RadTab component on IE 9 and Mozilla 5. In the other versions of IE, its behavior is ok. Don't know about other Mozilla versions. Follows more info about the issue.

I have a RadTab and a MultiPage. RadTab is linked with the MultiPage. I want a VerticalLeft RadTab, but, in these new versions, the RadTab persists at the top of the multipage and is showing as HorizontalTab. On other versions, it is working as expected. I've tried some CSS combinations, but none of them worked as expected.

Follows the code:

 

<telerik:RadTabStrip ID="rtsVertical" runat="server" MultiPageID="rmpCourseEdit"

SelectedIndex="1" SkinID="OutlookVTAB" Style="float: left">

<Tabs>

<telerik:RadTab Text="pgvBasic" PageViewID="pgvBasic" runat="server" Selected="True" /

<telerik:RadTab Text="pgvComposite" PageViewID="pgvComposite" runat="server" />

<telerik:RadTab Text="pgvTexts" PageViewID="pgvTexts" runat="server" />

<telerik:RadTab Text="pgvPub" PageViewID="pgvPub" runat="server" />

<telerik:RadTab Text="pgvSpec" PageViewID="pgvSpecialist" runat="server" />

</Tabs>

</telerik:RadTabStrip>

<telerik:RadMultiPage ID="rmpCourseEdit" runat="server" SelectedIndex="0" RenderSelectedPageOnly="false" CssClass="MultiPageV">
... </>

Follows the CSS and Skins:
<telerik:RadTabStrip runat="server" SkinID="OutlookHTAB"

 Skin="Outlook"

 EnableEmbeddedSkins="False"

 Orientation="HorizontalTop"

 />

Can you help me with this guys?

tks,
