RadGridView.Items.PageChanged event does not fire

Hi,

I'm using a RadGridView and RadDataPager together:

<telerik:RadGridView Margin="0,0,0,0"

Name="grdGeneralPayments"

SelectionMode="Extended"

ShowGroupPanel="False"

ShowColumnFooters="False"

CanUserSelect="False"

CanUserInsertRows="False"

CanUserDeleteRows="False"

IsSynchronizedWithCurrentItem ="False"

MouseDoubleClick="grdGeneralPayments_MouseDoubleClick"

SelectionChanged="grdGeneralPayments_SelectionChanged"

Filtering="grdGeneralPayments_Filtering"

Filtered="grdGeneralPayments_Filtered"

ScrollViewer.VerticalScrollBarVisibility="Auto"

ScrollViewer.HorizontalScrollBarVisibility="Auto"

DockPanel.Dock="Top">

</telerik:RadGridView>

<telerik:RadDataPager Name="radDataPager" Margin="0,0,0,0" DockPanel.Dock="Bottom" PageSize="10" Source="{Binding Items, ElementName=grdGeneralPayments}"

PageIndexChanging="radDataPager_PageIndexChanging" />

The grid also has a checkbox select column.

//Because grid columns are auto generated we need to add the select row checkbox column ourselves.

GridViewSelectColumn selectCol = new GridViewSelectColumn();

selectCol.Name = "Select";

//Put select row checkbox column on LHS of the grid.

this.grdGeneralPayments.Columns.Insert(0, selectCol);

Desired behaviour:
The user selects a number of items on one page.
User navigates to another page.
User navigates back to previous page and the previously selected items are still shown as selected.

The following code was working using Telerik.Windows.Controls.GridView.dll version 2010.1.422.35:

public ApproveGeneralPayments()

{

InitializeComponent();

this.grdGeneralPayments.Items.PageChanged += new EventHandler<EventArgs>(Items_PageChanged);

}

        

private void Items_PageChanged(object sender, EventArgs e)

{

      this.SelectGloballySelectedItems();

      this.changingPage = false;

}

Since upgrading to Telerik.Windows.Controls.GridView.dll version 2012.2.607.40, the above event "Items_PageChanged" fails to fire.

NB. The method "SelectGloballySelectedItems" compares the items on the currently displayed page with those which have been previously selected across multiple pages and reselects them.

Any idea why the event isn't firing or is there a new way to achieve the desired functionality.

Thanks,
Mark

Automatically clearing RadGridView SortDescriptors on ReBinding ItemSource

Is there a way to cleanly get a RadGridView to clear its SortDescriptors everytime the ItemSource is refreshed with a new data source?

My problem is that I am loading different dataset (different columns) into a RadGridView and when there is sorting on one of the data set, after binding a new dataset to the same RadGridView, it is obviously remembering the SortDescriptor and throwing an error because the column it is trying to sort on no longer exists in the new set of data it is being bound to.

Also I am trying to do this in a clean MVVM (WPF) way so calling RadGridView.SortDescriptors.Clear() in the code behind of my WPF form is not the approach I'm looking for.

Any ideas?

Hello, I´m working with 2011.3.1116.40 WPF version, I handle Filtered event, when I follow these steps, FilterDescriptors doesn´t update correctly:

1- Check one filter item -> FilterDescriptors OK.
2- Uncheck "Select all" -> FilterDescriptors wrong. FilterDescriptos continues with the last value.

It happens on filtered method.

GridView cell spesific dynamic combo box editor

Hi,

I should implement a dynamic combobox to be WPF gridviews cell editor. I need to create the combobox to some specific cell (for example to row 3 and column 2). The data should get from database in moment the user is activating the cell editing.

Already i found examples how to create GridViewComboBoxColumn, but i need to do this to just one cell at the time and the data must be fetched from relational database dynamic. That is because the data can be updated to the database at any time by other user/process.

What to do next?

TileViewItem width

I am having no end of trouble trying to find the magic to force a single-column RadTileView layout, with all tiles expanding to take up their fully available width.

What property should I be looking for which determines how the tiles determine their width?

Implenting Blank new row issue on Filter/Sort

I am implementing my own blank row to display at the end of the grid where users will be allowed to enter new data.

I do this by adding an empty row to the end of my ItemsSource

The issue is on Filtering and Sorting the empty row is included in the action. I tried removing the row and then re-adding it on the Filtering/Filtered and Sorting/Sorted events but on re-add the item is added to the sorted position not the end of the grid. Any help?

For reference this is how I set my DataContext for the Grid.

public DataTable CurrentDataTable

{

get { return dataGridView.ItemsSource != null ? ((BindingSource) dataGridView.ItemsSource).DataSource as DataTable : null; }

set

{

CurrentSelectedTableName = value.TableName;

//BindingSource to sync DataTable and DataGridView

var bSource = new BindingSource {DataSource = value};

//set the DataGridView DataSource

dataGridView.DataContext = bSource;

}

Add and Unload Empty Row
