I had the following, (which worked till I upgraded my Controls)
a method which returned via an arraylist any and all RadGrids found on a page ..i.e.
Logger.findRadGrids(Page.Controls);
which is as follows
public RadGrid findRadGrids(ControlCollection collection)
{
RadGrid result;
foreach (Control ctrl in collection)
{
if (ctrl.Controls.Count > 0)
{
result = findRadGrids(ctrl.Controls);
if (result != null)
{
RadGrids.Add(result);
}
}
else if (ctrl.GetType() == typeof(RadGrid))
{
RadGrids.Add(ctrl);
}
else if (ctrl.GetType() == typeof(Telerik.Web.UI.RadGrid))
{
RadGrids.Add(ctrl);
}
}
return null;
}
I then iterated thru this arraylist...getting the ItemCommand which I could then validate commandtypes against authorizations per user.
and log these.
//Originally...
foreach (RadGrid grid in Logger.RadGrids)
{
grid.ItemCommand += new GridCommandEventHandler(grid_ItemCommand);
}
//Now (mixed versions of RadCtls requiring .WebControls and .Web.UI )
for
(int i = 0; i < Logger.RadGrids.Count; ++i)
{
if (Logger.RadGrids[i].GetType() == typeof(Telerik.Web.UI.RadGrid))
{
Telerik.Web.UI.
RadGrid grid = (Telerik.Web.UI.RadGrid)Logger.RadGrids[i];
grid.ItemCommand +=
new Telerik.Web.UI.GridCommandEventHandler( grid_ItemCommand);
}
else
{
Telerik.WebControls.
RadGrid grid = (Telerik.WebControls.RadGrid)Logger.RadGrids[i];
grid.ItemCommand +=
new GridCommandEventHandler( grid_ItemCommand);
}
}
//Authorize or disallow actions on Grids
public void grid_ItemCommand(object source, GridCommandEventArgs e)
{
GridDataItem dataItem = new GridDataItem(((RadGrid)source).MasterTableView, 0, 0);
Hashtable htValues = new Hashtable();
switch (e.CommandName)
{
case RadGrid.UpdateCommandName:
{
if (!PagePrivilege.EditData)
{
disallowAction(
"Not allowed to Edit any Data");
e.Canceled =
true;
}
dataItem = ((
GridDataItem)((RadGrid)source).EditItems[0]);
goto extract;
}
case RadGrid.DeleteCommandName:
{
if (!PagePrivilege.DeleteData)
{
disallowAction(
"Not allowed to Delete any Data");
e.Canceled =
true;
}
dataItem = e.Item
as GridDataItem;
goto extract;
}
case RadGrid.PerformInsertCommandName:
{
if (!PagePrivilege.AddData)
{
disallowAction(
"Not allowed to insert any Data");
e.Canceled =
true;
}
((
RadGrid)source).MasterTableView.GetInsertItem().ExtractValues(htValues);
goto logg;
}
extract:
{
dataItem.ExtractValues(htValues);
goto logg;
}
logg:
{
this.Logger.logEvent(e.CommandName, htValues, 1);
break;
}
default:
{
break;
}
}
Now with the new versions of the controls, this generated the following error
Error 109 No overload for 'grid_ItemCommand' matches delegate 'Telerik.Web.UI.GridCommandEventHandler'
How do I go about fixing this please
TIA

The signature of the ItemCommand handler of your grid seems correct, however in some places in your code I see that you have references to the Telerik.WebControls namespace for the ASP.NET version of the grid. Is it possible that some kind of collision between the Telerik.Web.UI and Telerik.WebControls namespace causes the error?
Additionally, check whether specifying the type of the second argument in the ItemCommand handler produces different result, namely:
public void grid_ItemCommand(object source, Telerik.Web.UI,GridCommandEventArgs e)

You are quite right/
(I have q4 2006 and q1 2009 RadAjax asp.net controls ..and hence the conflict)...Now (for the interim I have differentiated between them and added the same function for the Web.UI ,..and both run great.
Thx

You need to see what components your project references and remove any older references to Telerik RadControls. If you have WebSite project (different from WebApplication project), check web.config to make sure the web site does not reference any old version of RadControls from the Globacl Assembly Cache (GAC) or any other location.

Firstly
You can check the refresh path of your telerik.Web.Ui.dll (expand the node on Telerik.Web.UI.dll, in the Bin folder of your WebSite) to see the dll.Refresh ..sorta text container, which you can edit to the path where the new Controls were / are installed) .
My new updated instalation of Telerik Controls (2008), was put into the root folder of of my IIS folders..as per Telerik Suggestion/Documentation) ..eg
C:\Inetpub\wwwroot\Telerik_RadControls2009.1
2ndly
.........All my References to it, in each form/class...were changed to
using Telerik.Web.UI;
3rdy the Event handlers on my grids/controls all reference the correct telerik dll
eg. grvSchedule_InsertCmd(object source, Telerik.Web.UI.GridCommandEventArgs e)
4thly...the Web.Config icluding the MS Script resource handlers, Web Extensions and their Correct Versions
<
system.web>
<httpHandlers
<
add path="Telerik.Web.UI.DialogHandler.aspx" verb="*" type="Telerik.Web.UI.DialogHandler,

path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource"/>
</
handlers>
</
system.webServer>
Remember the MS System.Web.Extensions / resources if using asp:Scriptmanager as opposed to using the telerik Scriptmanger (Required for Ajax Callbacks).
If you still have problems,..clean the GAC (in some deep hidden directory somewhere) bit of a mission,..but search Telerik and Google that for more instructions.
