I'm testing demo version.
I need do this...

          menuString = null;

          menuString = menuString +
                       "<telerik:RadRibbonBar ID=\"RadRibbonBar1\" runat=\"server\" Style=\"width: 100%\" Skin=\"Vista\"" +
                       " SelectedTabIndex=\"0\">" +
                       "<telerik:RibbonBarGroup Text=\"Search\">" +
                       "<telerik:RibbonBarGroup EnableLauncher=\"true\" Width=\"100%\" Text=\"Document navigation\">" +
                       "<Items>" +
                       "<telerik:RibbonBarButton Size=\"Large\" Text=\"First\" ToolTip=\"First Document\" Width=\"50px\"" +
                       "ImageUrlLarge=\"Images/resultset_first.png\" />" +
                       "<telerik:RibbonBarButton Size=\"Large\" Text=\"Previous\" ToolTip=\"Previous Document\"" +
                       "Width=\"50px\" ImageUrlLarge=\"Images/resultset_previous.png\" />" +
                       "<telerik:RibbonBarButton Size=\"Large\" Text=\"Next\" ToolTip=\"Next Document\" Width=\"50px\"" +
                       "ImageUrlLarge=\"Images/resultset_next.png\" />" +
                       "</Items>" +
                       "</telerik:RibbonBarGroup>" +
                       "</telerik:RibbonBarGroup>" +
                       "</telerik:RadRibbonBar>";

   myDiv.innerHTML = menuString ;

MyDiv is a Div in page.aspx.

The problem is that RadRibbonBar doesn't show in page, but exist in code behind when see generate code of aspx.

What is the problem?

Windows Server 2008 R2 Performance

Hi,

I'm currently developing a quite complex web application utilizing the Telerik RadControls ASP.NET AJAX (build 2010.3.1317.35) .

Everything is fine while I run my application on my Visual Studio 2010 Development Server or on a Windows Server 2003, but when migrating to a Windows Server 2008 R2 machine performance drops DRAMATICALLY. More precise: Whenever a postback is triggered there is a 4-5 second delay until the server responds, indepently on the complexity of the triggered code behind. I have already tried different machines, reinstalled the OS multiple times and still...

The OS installation is clean, nothing running except IIS. The Database runs on a independent server - connectivity to the database server isn't an issue here too.

RadGrid in a FormView

Hi All,

I've got a RadGrid inside a formview. In the DataBound event of the formview I need to add the ItemDataBound event handler for the RadGrid. I can find the grid just fine using the formview.FindControl method but once done I cannot see the event in the list of properties and methods for a RadGrid. I was thinking that the below should work:

Dim uxRadGrid As Telerik.Web.UI.RadGrid = DirectCast(uxFormView.FindControl("uxRadGrid"), RadGrid)

uxRadGrid.ItemDataBound += New GridItemEventHandler(uxRadGrid_ItemDataBound)

From c# examples it appears to work but in VB.Net you can't access the event view uxRadGrid.ItemDataBound. How do I work around this? You can't even access the event when trying this outside of a formview.

Regards,

Jon

Step through nested sqldatasource in radgrid nestedtemplateview

I have a NestedViewTemplate within a RadGrid. Within the NestedViewTemplate I have two other Rad-grids showing data to the parent RadGrid. I'm using a sqldatasource with storedprocedures to populate the data - both on the parent and the embedded grids. The data is populating just fine for all grids. However, when attempting to update the embedded grid, I get the error message:

Procedure or function 'x' has too many arguments specified.

I was already able to debug the parent sqldatasource becuase I received the same error. I did so following another thread on the forum describing how to identify the sql parameters using the sqldatasource updating event to identify the parameters being passed to the data source as well as the names. However, the Visual Studio 2005 code-behind page doesn't recognize the embedded sqldatasource events. If I manually create it, I get a compile error. How can I set up one to view the parameters being passed?

I implemented the second type of virtual scrolling on the following page.

Radgrid selected Item to Selected_item table in databas.

Hi Guru's
I am working on the RadGrid control & stuck at a point where I want to basically do the following operation:

I have a button named "Update"
then a radgrid

The requirement is as follow: The user visits the site on load of the page he will see the grid with the selected items that he had selected in his last visit... we have these values from the database,

Now when he selects the new row I have a table in the database named : "userselected" I want that his userID should be added in the list with this new itemno that he has selected..

I am using entity framework to communicate to the database.

thanks in advance
SPTECH

radmaskedtextbox ontextchanged

<telerik:RadMaskedTextBox ID="PostalCode" runat="server" Text='<%#Bind("PostalCode")%>' 
                                  Mask="L#L #L#"  OnTextChanged="PostalCode_OnTextChanged" AutoPostBack="true" Width="50" />
I'm having trouble with the ontextchanged event of the radmaskedtextbox.

I enter my postal code into the mask and tab to the next field. It posts back and calls the ontextchanged event.
However, the first time is posts back, the text value is blank "". 
If i enter the postal code a second time, the ontextchanged event picks up the value.

It seems it needs a postback to actually change the value in the  page, but the ontextchanged event runs before the value has been changed.

Is there a workaround for this behaviour?

TabStrip with Export Grid problem and Submit Form problem

I'm using a tabstrip control with 3 tabs.

- tab 1 is static content - works fine

- tab 2 is a RadGrid (data loads fine, paging is fine, details all fine, however commanditem export doesnt work.
- note i put the same grid in a page by itself (no tabs) and export work just fine.

- tab 3 is a form of user fields with a submit button (in buttonclick event, data is saved to sql db). When debugging form seems to work fine. i can set a break point on ButtonClick and it gets called everytime and data is properly saved. When the page is put on production server buttonClick event doesnt seem to fire. I put the exact same code outside the tabcontrol and it work perfect on production server and debug. buttonclick always fires.

I'm using whatever the newest version of rad controls is, as of this post.

thoughts?
