DataGrid UI virtualization

i have a D开发者_如何学运维ataGrid. And a bind a List<> to it and add at runtime in the code a few columns. After adding this columns the vertical scrolling isn't very good. The added columns in code are dynamic created, i think between 10 - 50. And there are about 140 rows. How can i fix it?

I read something about ui virtualization, but i dont understand how use it on a DataGrid? Can someone help me to finde a solution?

Thanks....

You need a datagrid that supports UI virtualization for columns. I don't believe the free Microsoft Silverlight datagrid supports that.

Not sure if there's a solution for that, but I do want to point out that we sell a datagrid for Silverlight at Xceed that supports it.

You can set the width of each individual column, and you can also set some columns to occupy the remaining available space, example:

<DataGrid>
  <DataGrid.Columns>
    <DataGridTextColumn Width="100"/>
    <DataGridCheckBoxColumn Width="Auto" />
    <DataGridTextColumn Width="*"/>
  </DataGrid.Columns>
</DataGrid>
