Datagrid not rendering a row.

What is happening is I have a datagrid using DataGridTemplateColumn that consist of several hyperlinkbuttons, if you click on one everything works fine, new site opens in a new window and all is good until you return to the datagrid and run a new search for new data. the Datagrid will refresh with the new search result however the row in which you previously click on a hyperlink is empty. By that i mean the row that should be there is blank, the correct amount of space is taken but no data is rendered. From debugging i see the data for the row is there in the ItemsSource list. After more digging it appears that the editingTemplateData private member has been set and I suspect that is what is keeping the row from rendering. I do not see any way to cancel this edit or even comit the edit. is there some way to get the datagrid out of editmode for templates?

Any ideas on how to get around this issue? I find no way to cancel the edit or even commit it and move on from the code side. however, a work around i have found is to select another row (without clicking any of the templates controls) and then running a search to refresh the datagrid. what am i missing?

Re: Datagrid not rendering a row.

If you are using silverlight 2 make sure you have the dec 2008 version of the datagrid

Re: Datagrid not rendering a row.

Hi,

You could set DataGridColumn.IsReadOnly=true to those columns which donot need editing.

If you don't need editing on datagrid, set DataGrid.IsReadOnly=true would work.

Thanks,

thanks Ken that appears to have fixed it!

Re: Datagrid not rendering a row.

I had and have set the datagrid itself and both columns to read only .. that did not help my issue. it turns out that Ken was right and I was using a pre-December version of the datagrid and updating fixed my issue.
