Howdy Everyone,

I'd like to ask on how to hide/show telerik grids on the same window by clicking a button?

Here's my scenario: 
I have 3 buttons: the day, week and month. My default grid on the window is the Day Grid. When I clicked on the day button, the day grid would show up, when the week button is clicked, the week grid will and the day grid will hide, and lastly, when the month button is clicked, the month grid will show and the week grid will be hidden. Please help me since i'm new to your tools. Would greatly appreciate your help. God bless.

Hi Guys, 

I'd like to know on how to show/hide a RadGrid when a RadButton is clicked? I am using Visual Studio 2010, C#. 


Many thanks.

Creating a DragQuery method for setting the drag cue only seems to work when dragging the contents. When dragging the header the drag image is alway the TileViewItem itself. This method is called but has no effect.

       private void TileViewDragQuery(object sender, DragDropQueryEventArgs e)
        {
            try
            {
                if (e.Options.Status == DragStatus.DragQuery)
                {
                    e.QueryResult = true;
                    e.Handled = true;


                    e.Options.Payload = sender as FrameworkElement;
                    e.Options.ArrowCue = RadDragAndDropManager.GenerateArrowCue();


                    // Create Drag Cue
                    // Create a ContentControl. It will be used as a DragCue.
                    ContentControl dragCue = new ContentControl();
                    // Use a DataTemplate to "say" how the dragged item will be displayed.
                    dragCue.ContentTemplate = mainGrid.Resources["DragCueTemplate"] as DataTemplate;
                    e.Options.DragCue = dragCue;
                }
                else if (e.Options.Status == DragStatus.DropSourceQuery)
                {
                    e.QueryResult = true;
                    e.Handled = true;
                }
            }
            catch (Exception)
            {
                throw;
            }
        }

Hi all

I'm currently evaluating the grid for one of our main applications, and hit a few early bumps. Generally, I'm struggling a bit with the avaliability of the DataContext in cells, columns etc.

The Microsoft grid, while being a very nice control IMO is a bit of a letdown here. What I would be expecting from a grid is this:



This feels just natural and enables proper MVVM without any dirty hacks. Much to my delight, I could easily bind the IsVisible property of the column to a boolean property of my view model. When I tried the same thing with the header: fail. I then created a simple template and did the binding and discovered that the data context of my header is not just empty, but actually an instance of system.object. I have no idea what the reason behind this is. I sure didn't set this.

There's a few threads on the issue, in part with workarounds that make me *really* cringe:
http://www.telerik.com/community/forums/wpf/gridview/column-header-binding.aspx

I can't help but wonder why we have a distinction of cases, and why I end up with a random data context for the header  instead of the grid's data context. After all, it just works for other dependency properties and attached properties.

I'm near certain that this will become a problem for us somewhere down the road - because one of our devs wants to set a header dynamically, we do need localization, have custom templating for headers, or another reason I currently don't think about.

What's Telerik's point on this? Is this a know issue that might get fixed? Is it a deliberate choice made for a good reason I don't see? Is it a bug?

Thanks in advance,
Philipp

Hi, 
The following is my Xaml code:

I wanna show content of Lable (ID) when the user clicks to Button (btnDetail).
How can I do that?
Thanks for your helping.

I have a WPF radgridview with the first column being GridViewCheckBoxColumn. I have templated the header

When the user click on the checkbox in the header i want to udpate all checkboxes in the rows to checked or unchecked. I am trying to do that with this code by "cb is always nothing". Pls advise

I noticed in your watermark example, any change isn't saved on the undo stack.

Is there a way on a custom tool you can programmically add to the undo stack?

Thanks

I am new to the WPF RadGridView and have a simple question.   I need to implement a search which looks at all columns of all rows in a bound, virtualized,  WPF RadDataGrid.   After discovering that the "ChildrenOfType<GridViewRow>()" function only returns a list of visible rows,  I searched this forum for an appropriate technique.  

I say one technique involving the RadGridView's "Records" property.   The current RadGridView does not have a "Records" property.

I also saw a couple of hits recommending searching the underlying bound data source instead of searching the actual grid rows.   That's easy enough.

But once I find the desired row in the underlying bound data (in this case an ObservableCollection<T>), how do I determine the matching grid row - and move it into the visible set on the user's screen - in a way that still works if the grid is sorted in a different order from the underlying bound data source?  

Thanks!

I have a radgridview displaying in the rowdetail of another radgridview. a list of sublists. this works nicely. now i want to make sure that the columns of the sublists are all synchronised. to do this, i was thinking of registering the loaded inner lists and using the changing/changed events of the columns. I am currently still having difficulties, finding the right information within the events (changed column number, current width), but I am more concerned about other issues. how are these rowdetails handled, are they unloaded when closed? I guess i should then unregister the detail. what happens when scrolled out of visible area? as the radgridcontrol can handle a large amount of data, i can imagine i must take a few things into account i have not yet thought about.

<radgridview>
<RadGridView.RowDetailsTemplate>
<DataTemplate>
<radgridview ColumnWidthChanging="gridView_ColumnWidthChanging"
ColumnWidthChanged="gridView_ColumnWidthChanged"
Loaded="gridView_Loaded"/>
</DataTemplate>
</RadGridView.RowDetailsTemplate>
</radgridview>

I am fairly new to wpf and very new to the radcontrols, so be kind ;) ...

Is there a way to fire the cellvalidating event when the cell is changed, instead of when it is commited? I want to validate after each character that the user enters into a cell. I thought setting to property changed instead of focus lossed would do it, but then the property is not really changed until it is commited is it..

Thanks!
