I.m using the Xceed datagrid v.2 for WPF, the free one.

When I bind to the grid using:

grdExceed.ItemsSource = ds.Tables[TableName].DefaultView

with a dataset containing around 1000 rows it takes about 3 minutes for it to display.

Is it supposed to be that slow or what??? 

 

By default, a grid will take all the room that it requires; therefore, if it is not given a size constraint, such as when it is placed in a StackPanel, and a large amount of data items are present, UI virtualization will be lost—resulting in a significant loss in performance. To preserve UI virtualization when a grid is in a StackPanel, the MaxWidth and MaxHeight properties (or Width and Height) must be used to constrain the grid. As an alternative, a DockPanel or Grid can be used as both impose size constraints on their child elements.

Hi Jenny,

I am facing a problem with binding a datatable to xceed datagrid. Based on the search criteria my datatable changes. When I bind the grid to a datatable it is showing all columns as expected. But when I bind to the grid for the second time to a datatable which will have enterily different columns, grid is adding them to the existing columns instead of removing the old one and adding new ones.

Could you please let me know how can i solve this problem

 

Thanks,

Shiva

Sounds like you are replacing the DataSet in your dataGridCollectionView but not clearing the previous column definitions.

I would suggest that you try the following:

dgcv.ItemProperties.Clear();  (where dgcv is the existing dataGridCollectionView that you use to wrap your DataSet)

or

dg.Columns.Clear();   (where dg is your Xceed DataGrid object)

 I know that I do both, but not clear if one or both is required.
