Hi guys, I am new to WPF all together so not strong on concepts.

I have generated RadgridView and based on the selection of the cell in this Radgridview, I want to populate a new RadgridView.



The problem is how to pass this MyView object to Top-level ViewModel class so that it can initialize the second table that I want to generate based on the MyView object. I was thinking that when Top-level class will get notified about the new MyView object then it will set the DataSource for the second table to populate it.

Please let me know if you have any other suggestions. I am a new player :)

Thanks,
Mark

Hi,

I created a set of LINQ classes, Customers.Memberships.CertificatesUsed

    First, I want to display the records from the Certificates collection

    I tried the sample code below but it doesn't seem to work


How should I bind the grid to the Certificates list?

Next, I want to be able to filter the content of the grid based on the selected Membership ID from a separate combo box.

How do I do it?

Thanks!

Will loading 1m data in telerik data grid view will not consume too much memory?

Let's say PC specs is Pentium 4, 1.4GHz and memory is only 512 MB.

Will it be slow to load all data with this computer?

What's the best way to go about adding labels (counties within a state, specifically in my case) to one of the state SHP/DBF examples from the drill down demo? Is it done in the SHP file or can I do it from the DBF data?

Thanks in advance!

Hello All,

I have a very strange issue that unfortunately I cannot duplicate with a small sample application.  Figured I'd just throw it out there to see if anyone had something similiar.

We are using the latest version Q3 2010.

We add RadPane items to the RadPaneGroup dynamically using Code.

Steps:

• If I have say 5 panes visible, select any pane other than the last one
• Make another application active, for example Outlook, or Internet Explorer
• Go back to our new application
• You can see the selected pane becomes the last one

Has anyone ran into something similiar?

Thanks,

I have a complex object model so I need to throw up a separate form to add a new one instead of letting the user edit the rows in-place.  But I still like the idea of offering the "click here to add row" feature.  It's just that when I intercept the OnAddingNewDataItem event I'd like to do this:

        private void OnAddingRow(object sender, Telerik.Windows.Controls.GridView.GridViewAddingNewEventArgs e)
        {
            var editDialog = new MyFormView(null);
            var rowAdded = (bool)editDialog.ShowDialog();
 
            if (rowAdded)
                GridView.CommitEdit();
            else
                GridView.CancelEdit();
        }

But what happens is even when I Cancel out of the dialog box and call CancelEdit, the grid still shows a newly inserted row (with empty values).  How can I cancel the add that's in progress programmatically?

Update: similar thing happens when I intercept OnDeletingRow so I can throw up a confirmation dialog box - if the user hits Cancel I'd like to cancel the delete, otherwise commit it, but CancelEdit and CommitEdit don't do the trick

Hi,

I have a RadGridView inside the control template. I have binded the SelectedItem property with a property in view model. but it is not working property, when I select an item from grid view the view model property doesn't get set.

Please help me out.

I am using a RadPanelBar to allow my users to select a report category, then a report in the category. Once the user clicks the report the selected event is fired and I hide the RadPanelBar and go show them the report. If they come back to the report selection, I have left the RadPanelBar exactly as they left it, with the last report they selected highlighted. Everything thing up till this point is great. However, if they want to go back to the report they just saw, and select the already selected RadPanelBar item, no Selected event is fired. I've tried other RadPanelBar events such as MouseDown, etc., nothing works. Does anyone know how to detect the reselection of an already selected item?

I'm using a HierarchicalDataTemplate to display the RadPanelBarItems and it is bound to an ObservableCollection. I can have a MouseDown event on one of the TextBoxes in the template, but then it fires before the RadPanelBar Selected event. Therefore, it's very hard to know from the template MouseDown event what is going on. Is the user reselecting an item, choosing another, etc? It seems that to make an intelligent template MouseDown event handler work correctly, you are abandoning the RadPanelBar Selected property and doing it all on your own. Is there something I'm missing here?
