I tried looking at the WPF GridView example for server side paging/sorting/filtering and it failed with an error. However I looked at the code and you are simply using entity framework to do all the work.

Are there any examples where I can use a different ORM like Ormlite? We don't use entity framework and frankly don't want to.

The only other solution for us would be to switch to using something like Kendo because then it is much easier in the web.

Have a User Control that is called when a button "about" is pressed.

The UC works. Want to add a "Close" button that will close the window so it won't get orphaned later.

I could use the "IsVisible = Visibility.Collapsed;" which works but it is not really gone. The UC has to RadListboxes which collects different data in each box. When I use the "IsVisible = Visibility.Collapsed;" the box disappears. When click on the "About" button it reappears with previous data. I prefer to make it truly close/destroyed.

Is this possible and if so how? please.

What code do you need the XAML or the .CS?

hello

I am trying to implement a Grid View with row number column and pagination.That is, the row number can also be changed when the page is changed

but the code I wrote is that the row number column on each page is only 1 to 10. And by going to the next page the row number starts again from 1 and does not increase to 11 and more.

this is my cs code for row number:

public override FrameworkElement CreateCellElement(Telerik.Windows.Controls.GridView.GridViewCell cell, object dataItem)

        {
            TextBlock textBlock = cell.Content as TextBlock;

            if (textBlock == null)
            {
                textBlock = new TextBlock();
            }
            textBlock.Text = string.Format("{0}", this.DataControl.Items.IndexOf(dataItem) + 1);
            return textBlock;
        }

and xaml code:

<telerik:RadDataPager DisplayMode="all" PageSize="10" Source="{Binding Items, ElementName=RadGridView}"  />

also i need a label that represents the total number of Grid View rows. The value of this label must be updated by applying a filter or searching.

but my code always represents total number of Grid View rows and does not change with filtering.

Thanks!

Sara.

Have a RadListbox, in xaml have set (SelectionMode="Multiple").

Want the user able to copy a selected item(s) and paste it anywhere (text file, excel, etc.) having issue finding topics in forum that helps me complete the operation of "copy".

Is there a method to do this?

I have "Product" AutoCompletebox where the user type Product Name. When the user press enter, this "Product" will be added to the GridView and auto-focus to "Quantity "cell. (I've successfully developed this part.)

After the user type Quantity in GridView's Cell, I want to Commit and End Edit to this row and focus (cursor) return back to "Product" AutoCompletebox. This is the part that I don't know how to do it.

Currently I have tried something like the following:

But the above code cause "StackOverFlow" exception. How should I solve this problem?

P.S. I have developed this app with C# Wpf with MVVM pattern.

private void RadGridViewInvoiceItems_CellEditEnded( object sender, GridViewCellEditEndedEventArgs e )
{
      if ( e.Cell.Column.Header.ToString() == "Quantity" )
      {
           this.gridView.CommitEdit();
           this.productTextBox.Focus();
      }         
}

private void RadGridViewInvoiceItems_CellEditEnded( object sender, GridViewCellEditEndedEventArgs e )
{
      if ( e.Cell.Column.Header.ToString() == "Quantity" )
      {
           this.gridView.CommitEdit();
           this.productTextBox.Focus();
      }         
}

     Do you guys have an example of DateTime data virtualization?

My data is updating live. I need a way to update visual ranges every second as data comes in and scroll backwords with the scroll bar through historical data.

I have 2 observable collections one for the total data and one for the visible data.

In the example project I see it updating using the ActualVisiualRange event on the telerik:LinearAxis but as far as event args I only see e.Newrange.Minimum/Maximum which seems to be the Y range not the X... 

Insight would be helpful as im not sure how to update the X data which are DateTimes in this event...

Hi,

The RadGridView Control is taking a long time to render.

I followed exactly ALL of the recommendations listed here :
https://docs.telerik.com/devtools/wpf/controls/radgridview/performance/tips-tricks

10 Rows
5 Columns
Binding only preloaded string (no code exucution delay)

But still, there is a noticable delay. 
Loading an UserControl with a RadGridView in it from a TabControl for example freezes the ui for quite some time.
It will be really noticiable for the enduser.

It takes more than 3 times the loading time of a Microsoft DataGrid (see attachements), why ?

Regards.
