how to add a rad grid in sharepoint2010 webpart

[swathi vajja]

Hi support team ,

I am bit new to this telerik.

I installed RadControls for ASP.NET AJAX Q1 2010 SP1 ,And i want to place a rad grid in sharepoint webpart.

this my .ascx

 <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" RestoreOriginalRenderDelegate="false">
                <AjaxSettings>
                    <telerik:AjaxSetting AjaxControlID="grid">
                        <UpdatedControls>
                            <telerik:AjaxUpdatedControl ControlID="grid" />
                        </UpdatedControls>
                    </telerik:AjaxSetting>
                </AjaxSettings>
           </telerik:RadAjaxManager>
<telerik:RadGrid ID="grid" runat="server" BackColor="#0066FF" ForeColor="Black" al>
</telerik:RadGrid>

in code behind

 

dtCommonList = List.GetItems(QueryForSDM).GetDataTable();
                if (dtCommonList.Rows.Count > 0)
                {
                    grid.DataSource = dtCommonList;
                    grid.DataBind();

                    grid.Visible = true;
                }
                else
                {
                    Response.Write("no data");
                }

When i deployed thi sdeploy was successful, but when adding to page

Not enough permissions. Inherit your page class from RadAjaxPage if you are running under Medium trust level.

so i changed my package.template.xml file and add my custom CAS

<CodeAccessSecurity>
    <PolicyItem>
      <PermissionSet class="NamedPermissionSet" version="1" Description="Permission set for SouthwesternEnergy.Partners.Web.">
        <IPermission class="AspNetHostingPermission" version="1" Level="Minimal" />
        <IPermission class="SecurityPermission" version="1" Flags="Execution,ControlPrincipal,ControlAppDomain,ControlDomainPolicy,ControlEvidence,ControlThread" />
        <IPermission class="Microsoft.SharePoint.Security.SharePointPermission, Microsoft.SharePoint.Security, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"
        version="1" ObjectModel="True" />
        <IPermission class="System.Security.Permissions.EnvironmentPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Read="UserName" />
        <IPermission class="System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Read="$AppDir$;C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\CONTROLTEMPLATES\VisualWebPartProject1" Write="$AppDir$" Append="$AppDir$" PathDiscovery="$AppDir$" />
      </PermissionSet>
      <Assemblies>
        <Assembly Name="VisualWebPartProject1" />
      </Assemblies>
    </PolicyItem>
  </CodeAccessSecurity

but after that i am unable to deply solution so i added a custom target file as mentioned in this site

http://support.microsoft.com/kb/2022463

but it gave me another exception this time 

Server Error in '/' Application.

Is it possible to add radgrid into sharepoint webpart?

I added necessary dlls into bin.

and even changed assemblyinfo.cs 

[assembly: AllowPartiallyTrustedCallers()]

I just have one day left to complete this task. So kindly help to fix this issue.

I fixed this issue by changing this in web.config

 <trust level="Full" originUrl="" />

Hello,
perhaps you can also add a web.config entry for your / the telerik dll.
Do not change the web.conffig Entries manually :
