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.

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.

Two ToolTipManagers on one page?

I've got a page that has two different type of UserControls on it. Each UserControl has a RadToolTipManager, and each one can be used multiple times on the same page. When that happens, the tooltips load the data, but they disappear as soon as the data is done loading, so the user never sees what is loading. I think it's clear that I can't have multiple RadToolTipManagers with the same ID on the same page. But I'm trying to figure out the best way to resolve this...?

Here's the structure of the page:

MasterPage

Page.aspx

UserControl1.ascx (ToolTipMgr1)

UserControl2.ascx (ToolTipMgr2)

Is there a way for me to out the ToolTipMgr in the Page, or the MasterPage, and then add the target controls to it programmatically from the user controls? That would allow me to have one ToolTipManager for the entire page...

Thanks for your help!
Eddie

True/False to Yes/No

Hello,

We bind boolean values and it translates the value to True/False (via the ToString()) method. We often write code to translate this to Yes/No. Is there an easy way in markup to translate the True/False to Yes/No, or does this always have to be in code? If via the GridCheckBoxColumn, maybe?

Thanks.
