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

public void LoadExtraRow()

{

var itemSourceDataTable = CurrentDataTable;

if (itemSourceDataTable == null)

return;

var newRow = itemSourceDataTable.NewRow();

newRow.RowError = "NEW_ROW";

itemSourceDataTable.Rows.Add(newRow);

dataGridView.Rebind();

}

public void UnloadExtraRow()

{

var itemSourceDataTable = CurrentDataTable;

if (itemSourceDataTable == null)

return;

if (itemSourceDataTable.Rows.Count > 0)

{

var emptyRowToRemove = itemSourceDataTable.Rows[itemSourceDataTable.Rows.Count - 1];

if (emptyRowToRemove.RowError == "NEW_ROW")

{

itemSourceDataTable.Rows.Remove(emptyRowToRemove);

}

Binding RadMap Center not working

I have a RadMap, with an InformationLayer, in which I am drawing a MapPolygon and a MapPinPoint.

The MapLayer.Location of the PinPoint is bound to a Location property in the viewmodel, that raises PropertyChanged when modified.

When I change the location, in code, the MapPinPoint is drawn in the new location, so I'm pretty sure that I have the binding and the notification working right.

Now here's the thing - I want the map to center on that same location. So I've bound RadMap.Center to that same property. And that's not working - the center of the map does not change, even though the location of the MapPinPoint does, when both are bound to the same property.

Since the MapPinPoint is working, I have to assume that the property is working right, and that the RadMap is ignoring PropertyChanged events on Center.

So how, then, do I change the center of the map, through bound properties?

Filter question

Hi guys,

I am working on a piece of code written by some other person that uses Telerik. An issue I am trying to resolve right now involves GUI formatting.

In this picture, you can see that the "Country" column has been highlighted and is active (i.e. has Distinct Filter). But in this case, that little wine-glass-like icon on the left is grey instead of orange. Do you know how I can make that icon change colour when the column is active?

The classes that are involved are RadGridView, a class that overrides IFilteringControl, and a set of GridViewColumns.

Thanks.
