Generic way of displaying error message in master page while using RadAjaxManagerProxy

Hi,

I have a master page whenere my RadAjaxManager is added and in the content pages, I have RadAjaxManagerProxy .
Now I need to display success/failure messages on the content page events like (button clicks , grid update/ combobox changed etc) in a Label in MasterPage.
Right now I am wiring each control which can cause a failure/success message to the RadAjaxManager using the following code:
RadAjaxManager AjaxManager = (RadAjaxManager)this.Master.FindControl("RadAjaxManager1");
        //AjaxManager.AjaxSettings.AddAjaxSetting(RadButton1, Label1);

        Label lblMessage = (Label)this.Master.FindControl("lblMessage");
        AjaxManager.AjaxSettings.AddAjaxSetting(RadButton1, lblMessage);

This code works fine. But my concern is that in future we may add more buttons/grids/combo boxes in the page. Then I need to add the above code for all controls which may not a scalable solution. A new programmer may not know about the need to wire control as above.

So I was wondering if there is a way to do a generic wiring so that any event happening in the content page can update the label in the master page which is a common scenario.
I have a custom base class for all the pages. So a solution in the base class which will work for all the pages and future pages will be really great.
Any thoughts? Any help will be much appreciated. Thanks a lot..

Q1 2010: VS Crash revisited

We got a report of Visual Studio crashes still happening due to a bug in the Q1 2010 release of the VSExtensions (2010.1.309).

Running the attached patch by having Visual Studio closed first will help fix the problem.

Best regards,

P.S. Thanks Anthony C. for helping us with this one.

Advanced binding with Datapager Problem

I am using Advanced databinding method. When yapAfter button is clicked I add an item to my List stored in the session according to the specific index and I rebind my List. Also in NeedData Source event my List stored in the session is binded. There is no problem when Allowpaging is off in Listview. However when I turn on Allowpaging the items I added last to my List comes out at the beginning of the List. They are not listed according to the Index I assigned while adding.

Thanks,
Regards.

Urgency: VS2010 Designer Problem

Dear Telerik Team,

In my VS2010 solution, I refer to the newest telerik .dll libraries:
- Telerik.Web.UI.dll (version 2011,1,519,40)
- Telerik.Web.Design.dll (version 2011,1,519,40)

My VS2010 designer have nearly permanently problem to show the RadChart (and not only the RadChart) in the design of my aspx page. Refresh helps, however sometimes... :(

After drag-and-drop from Toolbox, the designer produces this error message:
"Error Creating Control - RadChart1[A]Telerik.Web.UI.RadChart cannot be cast to [B]Telerik.Web.UI.RadChart. Type A originates from 'Telerik.Web.UI, Version=2011.1.519.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4' in the context 'LoadNeither' at location 'C:\Users\koterec\AppData\Local\Microsoft\VisualStudio\10.0\ProjectAssemblies\vcxqtkpk01\Telerik.Web.UI.dll'.

Provide me the solution, please.
Thanks in advance.

What control could I use to represent deep hierarchy structure?

I'm going to build a hierarchy structure. Each layer contains about 12 columns and in total I'll have 7 layers of hierarchy.

I have used RadGrid Hierarchy nested table features on some of the pages which had 1-2 nested tables and it works fine, however, on this page because mainly there are 7 layers of hierarchy I can't use RadGrid Nested Tables as the 7th Nested table gets opened in the middle of the page in that case!

What other control could I use to represent such structure?

E.g. Master Detail View, not sure?

Thanks,

Grid

Selection problem

Hi! I have tried to understand grid basics by following the demos in the website but i can't get the selection right. I'm trying to select an item by selecting a row (i'm not sure that is possible), and i even tried to creat a column (GridButtonColumn) where i set the button as image button and the imageurl for the image i want but i can't get it right, cause it is always appearing a checkbox instead of the image and, althought it selectes the row it does not selects the item in the row (i put a breakpoint in the grid_SelectedItemChanged and it doesn't do anything).
I also tried to do this as an gridtemplatecolumn and it makes appear the image i want but every time i click on it, instead of selecting the row and the item, it gives me an error witch i don't really know whatit means.

Code for the gridButtoncolumn (and grid):

One more thing, i only know vb.net and not very much. I can handle html so if possible and the solution calls for code i would appreciate for it to be in vb.net, if is as to be in c# or javascript so be it.

Thanks,
FEST

What event do I need to use to insert child records in a grid?

As a follow up to the earlier question beneath, I'm trying to write some code to assign contacts to facilities.

http://www.telerik.com/community/forums/aspnet-ajax/grid/how-to-reference-parent-data-items-in-edititemtemplate.aspx

I'm following samples such as the one beneath but I'm unable to find the correct event that I need to use. I'm currently trying to use 'RadGrid1_InsertCommand' but I imagine that's not working because it's the event that would be used for inserting the parent 'Facilities'.

http://www.telerik.com/community/code-library/aspnet-ajax/grid/automatic-operations-in-hierarchical-grid-with-sqldatasource-control.aspx

Can someone tell me what event I need to be looking at?

Thanks,
Tim

Protected Sub RadGrid1_InsertCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs)

'This event is not firing when I click on the 'Insert' link. What event do I need to use instead?

Dim insertedItem As GridEditFormInsertItem = DirectCast(e.Item, GridEditFormInsertItem)

Dim parentItem As GridDataItem = e.Item.OwnerTableView.ParentItem

Dim datakey As String = parentItem.OwnerTableView.DataKeyValues(parentItem.ItemIndex)("FacilityID").ToString()

Dim contactId As Integer = (TryCast(insertedItem("colContactId").Controls(0), DropDownList)).SelectedValue

Dim conn As New SqlConnection(ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString)

Try

conn.Open()

Dim insertQuery As String = "INSERT into FacilityContacts(FacilityId, ContactID) values('" & datakey & "','" & contactId & "')"

Dim cmd As New SqlCommand(insertQuery, conn)

cmd.ExecuteNonQuery()

conn.Close()
