Hi ..

I'm Facing a problem in my RadGrid which is :

SessionDataSource used in all Edit forms in all demos ... and it is using primarykeyfields and a ( ? ) symbol which gets the selected index DataKeyValue ...

Unfortunately this property ( primarykeyfields ) does not exist in SqlDataSource .

I'm working on SqlDataSource on my project and I want to use the insert/update/delete commands which use CommandName and SqlDataSource

so..

any help for this problem .... I will be thankful

self hierarchy showing duplicated registry

Hello guys.

I'm trying to use self hierarchy, but, I'm having problems. My grid is showing a regristry 2 times in the grid, like:

file1.jpg
file2,jpg
file3.jpg
file3.jpg
file4.jpg
file5.jpg
file6.jpg
file5.jpg
file6.jpg

I'm using this example:
http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/selfreferencing/defaultcs.aspx

Self-Referencing Hierarchy using LINQ and Nullable Guids

Following the help from http://www.telerik.com/help/aspnet-ajax/grdselfreferencinghierarchy.html, I cannot seem to find a FilterExpression that works with my data source. I am using the NeedDataSource event to set the data source like this:

dcConnections dc = new dcConnections();

g.DataSource = dc.GetMetrics();

dcConnections is my DataContext, GetMetrics is a stored procedure that returns a list of Metrics. The Metrics have an ID and ParentID, both of which are Guids. ParentID can be null. So, from the example, I tried to set the FilterExpression like this:

if (Assembly.GetAssembly(typeof(ScriptManager)).FullName.IndexOf("3.5") != -1 || Assembly.GetAssembly(typeof(ScriptManager)).FullName.IndexOf("4.0") != 1)

{

g.MasterTableView.FilterExpression = @"it[""ParentID""] == null";

}

else

{

g.MasterTableView.FilterExpression = "ParentID IS NULL";

}

This errors out with "No applicable indexer exists in type 'Metric'", which makes sense, since I need to use the it.ParentID format to get to the column in the Metric normally, so I change it to this:

g.MasterTableView.FilterExpression = @"it.ParentID == null";

That errors with "Operator '==' incompatible with operand types 'Guid?' and 'Object'".

So now, I can't figure out how to compare the values of a Guid? in a FilterExpression. Normally, using == null would work for Nullable Guids. Any suggestions?

Exporting to excel - how to hide "Save As" dialog

I am using the grid view control and saving the grid rows to excel.
I was wondering if there is a way to specify the name of the file programatically and to not take it from the user.
The below function call always opens the Save As dialog -
RadGrid1.MasterTableView.ExportToExcel();

Any ideas would be greatly appreciated.

[Solved] SelectedTab - allow user to reselect it

I have a tab strip that does autopostback. I would like the user to be able to re-click the selected tab and have that scenario cause an autopostback too, so that I can refresh the data on the page. Currently the selected tab turns the user's mousepointer to a finger, indicating it can be clicked, but it doesn't do anything when the user clicks it. There is no postback.
