I have created an unbound grid as follows

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("GUID"))

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("P_ID"))

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("T_ID"))

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("Project_Name"))

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("T Information"))

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("File_Path"))

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("File Name"))

RadQueuedFiles.MasterTemplate.AllowAddNewRow = False

RadQueuedFiles.AutoSizeRows = True

RadQueuedFiles.Columns(0).IsVisible = False

RadQueuedFiles.Columns(1).IsVisible = False

RadQueuedFiles.Columns(2).IsVisible = False

RadQueuedFiles.Columns(3).Width = 0.15 * Me.RadQueuedFiles.Width

RadQueuedFiles.Columns(4).DisableHTMLRendering = False

RadQueuedFiles.Columns(4).Width = 0.55 * Me.RadQueuedFiles.Width

RadQueuedFiles.Columns(5).IsVisible = False

RadQueuedFiles.Columns(6).Width = 0.35 * Me.RadQueuedFiles.Width

RadQueuedFiles.AllowEditRow = False

RadQueuedFiles.AllowAddNewRow = False

Dim descriptor As New GroupDescriptor()

descriptor.GroupNames.Add("Project_Name", System.ComponentModel.ListSortDirection.Ascending)

Me.RadQueuedFiles.GroupDescriptors.Add(descriptor)

When I run the program and add rows programatically, it groups by value in GUID column and not the project name... sample add is below

RadQueuedFiles.Rows.Add(Guid.NewGuid, cboProjectName.SelectedValue, RadT.CurrentRow.Cells(0).Value, cboProjectName.Text, strProjectIdentifier, file, file.Split(

"\")(file.Split("\").Count - 1))

What am I missing?

Hello,

To avoid this, please wrap your add statements in a BeginUpdate / EndUpdate
exmaple

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("GUID"))

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("P_ID"))

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("T_ID"))

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("Project_Name"))

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("T Information"))

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("File_Path"))

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("File Name"))

RadQueuedFiles.MasterTemplate.AllowAddNewRow = False

RadQueuedFiles.AutoSizeRows = True

RadQueuedFiles.Columns(0).IsVisible = False

RadQueuedFiles.Columns(1).IsVisible = False

RadQueuedFiles.Columns(2).IsVisible = False

RadQueuedFiles.Columns(3).Width = CInt(0.15 * Me.RadQueuedFiles.Width)

RadQueuedFiles.Columns(4).DisableHTMLRendering = False

RadQueuedFiles.Columns(4).Width = CInt(0.55 * Me.RadQueuedFiles.Width)

RadQueuedFiles.Columns(5).IsVisible = False

RadQueuedFiles.Columns(6).Width = CInt(0.35 * Me.RadQueuedFiles.Width)

RadQueuedFiles.AllowEditRow = False

RadQueuedFiles.AllowAddNewRow = False

Dim descriptor As New GroupDescriptor()

descriptor.GroupNames.Add("Project_Name", System.ComponentModel.ListSortDirection.Ascending)

Me.RadQueuedFiles.GroupDescriptors.Add(descriptor)

Me.RadQueuedFiles.BeginUpdate()

RadQueuedFiles.Rows.Add(Guid.NewGuid, "P_ID", "T_ID", "PROJECT NAME1", "T_INFORMATION", "FILE PATH", "FILE NAME")

RadQueuedFiles.Rows.Add(Guid.NewGuid, "P_ID", "T_ID", "PROJECT NAME2", "T_INFORMATION", "FILE PATH", "FILE NAME")

RadQueuedFiles.Rows.Add(Guid.NewGuid, "P_ID", "T_ID", "PROJECT NAME3", "T_INFORMATION", "FILE PATH", "FILE NAME")

Me.RadQueuedFiles.EndUpdate()

hope that helps
Richard
