Hi,

so I spent a lot of time (too much) on a 3 level hierarchy.
The webapp is currently being used.

So I have spent a LOT of time answering phone calls and emails from users. Also held some courses for them. (Keep in mind none of the users are IT people, quite the opposite).
I also have a nice colored box on top of the page with instructions on how to use it. The first line of the info box is in bold text and says:
Use the + - on the left to collapse-expand: [level 1 name] [level 2 name] [level 3 name]

And still, it was the most frequent problem. So I switched to "PushButton" to expand-collapse. Still a problem...
So, I've had to rethink the whole layout, and walk away from the 3 level hierarchy grid (again, but this time I've learned to stay away from those)..
I have to admit it can look confusing when you have a lot of data in there. Mostly, I think it looks too impressive: users will automatically think "wow, this looks hard", and first impressions last forever...

Now working on a new layout, with a combo to select top level item... A treeview listing the level 2&3 items, and an iframe showing details of the selected item.
Performance was also becoming an issue very quickly with a 3 level hierarchy, even with paging set to 5 for the top level item...
Personally, I was very happy with the result (thanks to support), but the confused users forced me to rethink the whole page...

What's your experience with a 3 level hierarchy grid? If you've had any success with it, I'd like to know...
If you ended up "burned" like me, it'd also be interesting to hear.

Best regards,
Nicolai

Hi,

I have made a webpart for sharepoint that uses the radchart. The radchart appears in the webpart but has message to add following to my web.config:
<add path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Version=2009.2.826.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false" />

When I add the above line, I start getting the following error. If I remove the line, the error goes away

Dear Telerik,

I would like to use the (context)menu in a radgrid. However I wish to show the context menu when the user hovers over an edit-image (no right click) inside the grid. I need a postback to do some serverwork and I need the value of the DataKeyName of the rowindex clicked.

What is the best approach? Is there an example/demo online that uses this technique?

Best wishes

Hello, Telerik support team!

Could you describe me how to solve a problem I have please.
I have an RadSlider on the web page. When its ItemType property is set to "Item", I can't force the Drag handle to be placed directly on graduation marks. It's possible only if ItemType property is set to "Tick", but I can't use slider so.
How can I force Drag handle to be displayed only on graduation line(s) instead of between of them?

Take a look at the attached png file with some description please.

Thank you a lot.

I need to access a value that is common to all rows when I run the insert command. How is the best way to accomplish this?

I create
 <CommandItemTemplate>
                                         <table width="100%">
                                          <tr>
                                            <td>
                                             <asp:LinkButton ID="btnAdd"
                                              Text="Add New Content of Course" CommandName="InitInsert" Runat="server"></asp:LinkButton>
                                            </td>
                                            <td>
                                              <asp:LinkButton ID="btnDelete"
                                              Text="Delete Content" CommandName="Delete" Runat="server"></asp:LinkButton>
                                            </td>
                                        <td>
                                         <asp:LinkButton ID="btnRefresh" Text="Refresh data"
                                          CommandName="Rebind" Runat="server"></asp:LinkButton>
                                        </td>
                                          </tr>
                                         </table>
</CommandItemTemplate>

        }

    }
Please help me to solve this problem as impossible as. Thanks alot.

I have a Grid using automatic inserts. My Primary Key database field "USER_Pin" is an integer.  I prompt for this key using a RadNumericTextBox. However, on my INSERT I get the following error: 
Cannot insert the value NULL into column 'USER_Pin', table 'RTS.dbo.tblUsers'; column does not allow nulls. INSERT fails.The statement has been terminated.

If I change this RadNumericTextBox to a RadTextBox, the INSERT works.

I have tried changing the SqlDataSource Parameters datatypes to string, int16, even removing the type, etc..  nothing seems to work for the RadNumericTextBox

<InsertParameters>
  <asp:Parameter Name="USER_Pin" Type="Int16" />
  <asp:Parameter Name="USER_Name" Type="String" />
  <asp:Parameter Name="USER_Email" Type="String" />
  <asp:Parameter Name="USER_Override_Email" Type="String" />
  <asp:Parameter Name="USER_Privilege" Type="String" />
  <asp:Parameter Name="USER_Status" Type="String" />                
</InsertParameters>

What am I missing??

Hi,
While I copy from word into the RAD Editor, I want the font types and sizes removed and keep other formats intact - like Bold / Italics etc. The following does not work for me.

 

 

 StripFormattingOptions="Span, MSWordRemoveAll,Css" StripFormattingOnPaste="Span,MSWordRemoveAll,Css"

I use the version 2009.1.527. I believe this is the latest version. Can you please help me with the problem.

Thanks.
Anandi
