Dear Telerik,

When i am exporting to excel its creating a folder with the same excel file name and it contains (filelist.xml, sheet001.htm, stylesheet.css, tabstrip.htm) if i want to give this file to anyone i have to send this folder along with excel file and the other issue is when i try to open excel file it says "The file you are trying to open 'StockLedger.xls', is in a different format than specified by the file extension.
Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?" 

 I am using MS Office 2010 and I am using Build WPF 2012.2.0703.

Thanks in advance...

Mohammed

Hi everyone,

I'm trying to make a spline chart with thousands of values with the Y-Axis being an integer value and the X-Axis being a datetime value and I don't know how to fill both the integer and the datetime values. I was trying to set the itemsource of the chart as an array, but I couldn't get it, I couldn't show the datetime values. The charge of the information is made in a dynamic way. Any help would be appreciated.

Thanks!!

Hi all. I have several problems with rotated gridview. So, when grid rotated to 270 degrees and Horizontal Alignment set to Left it's makes as square and don't grow up when populating data take more space than he had. It's look like alignment applied to both vertical and horizontal sides.
Second issue with... it's hard to describe. I have two grid's. First does not rotated, second rotated to 270 degrees. When i set IsFilteringAllowed to false for rotated grid it's start jump... or have a long love with not rotated grid. I think it's some problems with window size and scrolling of gridview... You can see this at video: https://skydrive.live.com/redir?resid=8921E2784A54CF76!137&authkey=!AKe9e5QHUKdJtEw

Hello!, I have a RadGridView, that it's itemsSource is an Observable Collection, and when an item of the collection changes, it also changes in the RadGridView, the problem is that the changed element moves to the last row, and I don't want it to move, or to move to the first row, but not the last, anybody knows how to change it? or how I can get the RadGridView ordered when it happens?
Thanks!

Hi,

I have a gridview with 3 GridViewComboBoxColumn's first comboboxcolumn holds different states, based on the selection the second and third comboboxes are populated. the second comboboxcolumn holds different Id's and the third comboboxcolumn holds descriptions. Each row has its own set of states, id's  and descriptions. each Id can have one or more descriptions and the user can select either the Id first or description first, so both this comboboxes are populated with same data with different properties. till now everything works fine. but we have a requirement that whenever the selected Id has only one description associated, we should default the description selection to that on the other hand it there are more than one description associated with the id we should sort the descriptions to have selected Id's descriptions to the top. After this change for some reason the getter for description comboboxcolumn itemsourcebinding property is called continuously and the entire application hangs. Below is the code snippet of the view and viewmodel. Please let me know if you need addtional information and what am I doing wrong?

View:

Hello,

I've successfully implemented an editable GridView using a custom row layout.  However, there appears to be a bug that prevents inserting more than 1 new row when using a custom row layout. After the successful initial insertion of a new row, subsquent calls to BeginInsert() return false.  I've tried preceding the call to BeginInsert() with various statements to ensure that any pending edits or insertions are commited, but no success.  

I've replicated the problem using the RadGridView Custom Row Layout online demo and setting the IsReadOnly property to false.  Only the first insertion works.  Can you confirm this behavior and propose a solution?

Thanks in advance..

Hi Support Team,

I am using following code to create column Group at run time .
To create a new group programmatically use :
GridViewColumnGroup columnGroup = new GridViewColumnGroup();
columnGroup.Name = "XXXXXX"; // replace the XXXX with a name of your choice...
To tell a column it belongs to a given group use : 
this.RadGridView1.Columns[0].ColumnGroupName = "XXXXXXX";
To add a programmatically created group to RadGridView use :
this.RadGridView1.ColumnGroups.Add(columnGroup);
I am creating grid columns at run time based on business requirement and for some columns which are constant and added at design time  is also having column group strip with Black color which user does not like so I want to get rid of that color and make its color as Rad Grid backgroud color. Screen shot of the issue has been attached with this thread.
Please help me to resolve this issue. Please have a look in the attachment. If you do not understand please let me know so I can post code as well. It happens in both the versions which are following:

Telerik\2011\Q3\WPF\2011.3.1220
Telerik\2012\Q2\WPF\2012.2.725

In the above markup I added a Label control, Panel and controls in GridViewColumnGroup.HeaderTemplate. In  the Panel added 4 buttons. My issue is I can't able to find those control which are added in GridViewColumnGroup.HeaderTemplate in code behind .cs file. I need to update the Label content and set the button enable and disable as per business requirement.  

Please help me to resolve this issue.

one more issue I have is I am adding columns in the grid at run time and assigning those column ColumGroupName="MonthName" which I set in Markup but first time it work fine when and sets a comon Column Group Header. I click on next button I am creating some more columns again in the grid and adding with same  ColumGroupName="MonthName" in that case, for next time dynamically added columns the ColumnGroupName is not working so It is not putting next time dynamically added column in the same Colum Group Header.

Waiting for your quick response.

Thanks
Laxman
