I am attempting to filter on a column in a simple grid i created but I get the following error:
Unable to cast object of type 'ASP.ui_navs_mainlayout_master' to type 'Telerik.Web.UI.GridTableView'

Am I missing something from my .NET application?

It looks like you may be trying to access the Grid's MasterTableView inaccurately in your code. Can you post the relevant snippets of any code that you're using with your RadGrid? With that info, I think this problem will be easy to solve.

I read something that you can't use DataBind if you are using filtering...is that true?
Here is my code:

 

<telerik:RadGrid ID="GridView1" runat="server"

 

 

AllowFilteringByColumn="True" AllowSorting="True"

 

 

GridLines="None" Skin="WebBlue">

 

 

<MasterTableView>

 

 

<ExpandCollapseColumn>

 

 

<HeaderStyle Width="20px" />

 

 

</ExpandCollapseColumn>

 

 

<RowIndicatorColumn>

 

 

<HeaderStyle Width="20px" />

 

 

</RowIndicatorColumn>

 

 

</MasterTableView>

 

 

<FilterMenu EnableTheming="True">

 

 

<CollapseAnimation Duration="200" Type="OutQuint" />

 

 

</FilterMenu>

 

 

</telerik:RadGrid><br />

Code Behind:

 

 

Sub FillGrid()

 

 

Dim cmd As OleDbCommand = New OleDbCommand

 

 

Dim dReader As System.Data.OleDb.OleDbDataReader

 

oConn.Open()

cmd.Connection = oConn

cmd.CommandText =

" select /*+ all_rows */ rownum, defect_num, program_desc, change_reason, change_desc, close_date " & _

 

 

" from hw_ir_productivity t " & _

 

 

" where program_desc in ('" & leftSideMenu.GetProjects.Replace(",", "','") & "') " & _

 

 

" and to_date(close_date,'mm/dd/yyyy') >= to_date('" & HttpContext.Current.Session("varStartDate") & "','mm/dd/yyyy') " & _

 

 

" and to_date(close_date,'mm/dd/yyyy') <= to_date('" & HttpContext.Current.Session("varEndDate") & "','mm/dd/yyyy') "

 

 

 

dReader = cmd.ExecuteReader()

GridView1.DataSource = dReader

GridView1.DataBind()

dReader.Close()

oConn.Close()

 

End Sub

I also just tried removing the DataBind and doing something similar to this
http://www.telerik.com/help/aspnet-ajax/grdbindingtodatareader.html

but I get the same error.

No, but I am curious where you're calling FillGrid from. If you are manually binding your grid, you should probably use the NeedDataSource event to support operations like paging, sorting, and filtering. See this demo for a complete explanation of the event and an example of how that event works:


Also, on a side note, I'd highly encourage you to change your SQL from using string concatentation to using strongly typed parameters. This will significantly improve the security of your application and leave you less vulnerable to SQL injection attacks. Here's an example of that approach if you need it:

OleDbCommand SelectCommand = new OleDbCommand("SELECT ID, Name, Email FROM Customers WHERE (ID = ?) AND (Name = ?)",this.oleDbConnection1); 
 
SelectCommand.Parameters.Add(new System.Data.OleDb.OleDbParameter("ID", System.Data.OleDb.OleDbType.Integer)); 
 
SelectCommand.Parameters.Add(new System.Data.OleDb.OleDbParameter("Name", System.Data.OleDb.OleDbType.VarChar)); 

Hope that helps.

What's odd about your error is that it looks like your page is trying to cast a reference to the ASP.NET generated class for your masterpage to the type "Telerik.Web.UI.GridTableView." Are you sure there is no other code in you code behind that could be contributing to this? Is the class reference in your @Page registration correct?

Try using the "Format Code" toolbar button in the forums to post the complete code for your APSX and code behind. That will help me see what could be causing this strange error outside of the grid.

As you can see in the code, I've made my old grids (from telerik for ASP.NET) invisible while I replace them with new grids from telerik for ASP.NET AJAX.

Hi, I followed your advice from the link and I still get the same error.

My old grids that use RadGrid for ASP.NET worked fine (but slower of course).  The new ones are the same...just replacing the old ones.  Is there anything new in ASP.NET AJAX that might cause this error.  Like you said, looks like it has to do with the master page?

ok, I just tried a very simple example on a new aspx page and I get a very similar error when attempting to filter on a column:

Unable to cast object of type 'Telerik.Web.UI.RadGrid' to type 'Telerik.Web.UI.GridTableView'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

It's starting to sound like you may have a web.config configuration error. I'd suggest you create a brand new project with Telerik's controls and then compare the web.config to your current web.config. You need to make sure the handlers for both ASP.NET AJAX and the RadControls are configured correctly.

See this thread for some additional ideas from people who had a similar problem:

I created a new aspx page and dragged a grid from the toolbox to the aspx page, then copied changed from the new web.config to my projects web.config.  I still got that error.  I am using VS 2005, not 2008.  I had to install ajax extensions and alter the web.config at that point.  Maybe I missed something?  Can you send me an example of a valid web.config so I can determine what I may be missing?

Take a look at the web.config that comes with the RadControls Live Demos, usually located at %Program Files%\telerik\RadControls for ASPNET AJAX Q2 2008\Live Demos. That should be a good reference.

You can also review the "base" ASP.NET AJAX web.config at %Program Files%\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\v1.0.61025.

I'd suggest using a diff program to compare the web.configs. My favorite is Beyond Compare, but any differ will do. Hope this helps!

I tried adding all the info to my web.config from the "live demos" section but it created another error.

I'm including my web.config.  Could you please take a look to see what I might be missing as I have already tried to replace most of this file without any luck.  Thanks.

fyi - i replaced some of connection info due to privacy issues.

Still no luck.  I've tried numerous changes to my web.config file.  I am running VS 2005.  Would that be a problem?  Does filtering work with 2005?

I just tried to use a RadAjaxManager but got the following error when running the app...
I am defintely missing something that is prohibiting these controls from working.  If you could provide me of a list of things needed to run these controls I would appreciate it.  thanks.

Todd-

The second issue is unrelated to the first. When you use RadAjax to auto-ajaxify a page, you need to wrap any <% %> code blocks in a RadCodeBlock control. This enables RadAjax to correctly parse the page and eliminates the second error you've listed.

As for the original trouble, it's hard to say exactly what's happening since this is an evironment issue. The RadControls work fine with VS 2005 and .NET 2 + Ajax Extensions, so there is some error in your local configuration that is triggering this behavior.

At this point, I'd suggest that you try creating a brand new ASP.NET AJAX Website. Add the RadGrid to a simple page (along with the required ScriptManager) and see what happens. If everything is setup correclty on your PC, these basic steps should work. If they do, we can keep troubleshooting your app. If they don't, we know there's a bigger configuration issue at play that needs to be solved.

Give that test a try and let us know what happens.

I added the Code Block around the controls.  The <% and %> are actually in javascript on the ascx page.  I don't see the same error now after adding the Code Block control but I am now seeing a javascript error:
Error: 'Sys.WebForms.PageRequestManager' is null or not an object.
I am including the code for the ascx page.  Could you please tell me if I have included the RadCodeBlock in the correct location?  Thanks.
Also, I'll try creating a new project and see if that fixes the other issue.

The expandwindow and shrinkwindow javascript functions are called from the page load in the code behind:

imgProjectsOpen.Attributes.Add(

"onClick", "return expandWindow('lbProject');")

 

imgProjectsClose.Attributes.Add(

"onClick", "return shrinkWindow('lbProject');")

 

imgSubsystemsOpen.Attributes.Add(

"onClick", "return expandWindow('lbSubsystem');")

 

imgSubsystemsClose.Attributes.Add(

"onClick", "return shrinkWindow('lbSubsystem');")

 

imgCauseCodesOpen.Attributes.Add(

"onClick", "return expandWindow('lbCauseCode');")

 

imgCauseCodesClose.Attributes.Add(

"onClick", "return shrinkWindow('lbCauseCode');")

 

imgDirectoratesOpen.Attributes.Add(

"onClick", "return expandWindow('lbDirectorate');")

 

imgDirectoratesClose.Attributes.Add(

"onClick", "return shrinkWindow('lbDirectorate');")

I have figured out my errors.  Looks like the ScriptManager needs to be on the same page as the controls.  I had included it on the master page as I had read somewhere, but obviously you run into issues with that approach.

I see...I must have overlooked that in your code. Yes, when you use MasterPages, you can run in to trouble with the ScriptManager in some scenarios. The best guidance for MasterPages is to use the ScriptManager on your MasterPage and then use ScriptManagerProxy controls in your ContentPages and your UserControls.

Either way, happy you found your solution!
