Getting DataGrid Cell Data

lifewarped · February 10th, 2005, 12:27 PM

Im working on a client with mouseover controls on a DataGrid to make life easier on a user who is very perticular as to how he wants to do things. However i cant pull the Data out of the Cell. I tried pulling it from the DataTable, but when the grid is resorted by the user the DataTable is not, and thus when the data i am pulling is incorrect. Is there a way to work around this? Im working in C# but i can read any .NET Language...

I just did this the other day, to reformat a column in the datagrid. In it, I overloaded the data binding method of the datagrid so that I could display a link depending on the content of the cell. Hope it gives you an idea of how to access it.

Protected Sub myDataGrid_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs) Handles myDataGrid.ItemDataBound
If (e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem) Then
   If (e.Item.Cells(column_typeID).Text = "fldr") Then
      e.Item.Cells(column_fileID).Text = "<a href='ScreenFolders.aspx?objid=" + e.Item.Cells(column_fileID).Text + "' target='_blank'>View Folder</a>"
   ElseIf (e.Item.Cells(column_typeID).Text = "file") Then

      e.Item.Cells(column_fileID).Text = "<a href='Screenfiles.aspx?objid=" + e.Item.Cells(column_fileID).Text + "' target='_blank'>View File</a>"
      End If
   End If
End Sub

Thats nice code... However im working with WinForms and the WinForm DataGrid. i Did however fix the problem.
C#

Code:

Ã  BindingManagerBase bm = 
Ã  Ã  ((System.Windows.Forms.DataGrid)sender).BindingContext[ 
Ã  Ã  Ã  ((System.Windows.Forms.DataGrid)sender).DataSource, 
Ã  Ã  Ã  ((System.Windows.Forms.DataGrid)sender).DataMember]; 
Ã  DataRow dr = ((DataRowView)(bm.Current)).Row;

VB (Converted by hand from C#, hope its 100% correct.)

Code:

Ã  Dim bm As BindingManagerBase = 
Ã  Ã  CType(sender, System.Windows.Forms.DataGrid).BindingContext( 
Ã  Ã  Ã  CType(sender, System.Windows.Forms.DataGrid).DataSource, 
Ã  Ã  Ã  CType(sender, System.Windows.Forms.DataGrid).DataMember) 
Ã  Dim dr As DataRow = CType(bm.Current, DataRowView).Row
