Update Parent Row in GridViewRelation

[Bao]

Hi ,

I have Hierarchical Gridview. When loading i loop all of the rows:

foreach(var row in datagridview1.Rows)

{

    if(row.Type == "Childrend")

         {

             var parentRow = row.Parent as GridViewRowInfo; <----- it returns Null

         }

}

How can i get parent Row of child Row when loading ? Now at the childRow, i can get the parent Id and i have to loop all of the gridview again to find the parent row by ParentId .

Hello Bao, 

Thank you for writing.  

If you iterate the RadGridView.Rows collection you are actually iterating the parent rows in the grid. That is why the cast is not successful. I have prepared a sample project for your reference where the CurrentRowChanged is handled. If you click a child row, its parent row's first cell value is extracted successfully. Please refer to the attached zip file.

Feel free to use our support ticketing system in future where you can provide a sample project demonstrating the exact problem that you are facing. Thus, Telerik support will gladly assist you.

I hope this information helps.
