problem with SelectedItem

Hi I was using the following with a standard listBox

Private Sub RadListControl1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.Data.PositionChangedEventArgs) Handles RadListControl1.SelectedIndexChanged

If RadListControl1.SelectedIndex > -1 Then

Dim tenants As Tenant = RadListControl1.SelectedItem

RadTextBox5.Text = tenants.ID

RadTextBox6.Text = tenants.FirstName

RadTextBox7.Text = tenants.Existing

RadTextBox8.Text = tenants.LastName

End If

End Sub

however when I try to use the RadListControl I get an error on this line

Dim tenants As Tenant = RadListControl1.SelectedItem

error Value of Type telerik.win.controls.UI.RadListDataItem ' cannot be converted to mainSystem.Tenant?

please advise

'RowIndex' is not a member of 'Telerik.winControls.UI.GridView.CellInfo'

Then what is the counterpart of RowIndex?

I have a form with a GridView on it and it displays the data i want it to perfectly, However I want to bring up an Add/ Edit form using a context menu strip to edit or add a record to the database. To fill the form for the edit part I need to do something like this(actually works when using the standard Data Grid)

Private Sub EditToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles EditToolStripMenuItem.Click

Dim frm As New frmAddEdit

frm.GUID_User = Me.dgvUsers.Item(0, Me.dgvUsers.SelectedCells(0).RowIndex).Value.ToString()

frm.GUID_Group = Me.dgvUsers.Item(1, Me.dgvUsers.SelectedCells(0).RowIndex).Value.ToString()

frm.txtADName.Text = Me.dgvUsers.Item(2, Me.dgvUsers.SelectedCells(0).RowIndex).Value.ToString()

frm.txtUserName.Text = Me.dgvUsers.Item(3, Me.dgvUsers.SelectedCells(0).RowIndex).Value.ToString()

frm.txtEmail.Text = Me.dgvUsers.Item(4, Me.dgvUsers.SelectedCells(0).RowIndex).Value.ToString()

frm.txtLogin.Text = Me.dgvUsers.Item(5, Me.dgvUsers.SelectedCells(0).RowIndex).Value.ToString()

frm.txtPassword.Text = Me.dgvUsers.Item(6, Me.dgvUsers.SelectedCells(0).RowIndex).Value.ToString()

frm.txtTelNo.Text = Me.dgvUsers.Item(7, Me.dgvUsers.SelectedCells(0).RowIndex).Value.ToString()

frm.txtFax.Text = Me.dgvUsers.Item(8, Me.dgvUsers.SelectedCells(0).RowIndex).Value.ToString()

frm.cbActive.Checked = IIf(Me.dgvUsers.Item(9, Me.dgvUsers.SelectedCells(0).RowIndex).Value.ToString() = "True", True, False)

frm.GUID_Company = Me.dgvUsers.Item(10, Me.dgvUsers.SelectedCells(0).RowIndex).Value.ToString()

frm.cbLead.Checked = IIf(Me.dgvUsers.Item(11, Me.dgvUsers.SelectedCells(0).RowIndex).Value.ToString() = "True", True, False)

frm.cbSplit.Checked = IIf(Me.dgvUsers.Item(12, Me.dgvUsers.SelectedCells(0).RowIndex).Value.ToString() = "True", True, False)

frm.cbTelesales.Checked = IIf(Me.dgvUsers.Item(13, Me.dgvUsers.SelectedCells(0).RowIndex).Value.ToString() = "True", True, False)

frm.cboOffice.SelectedValue = Me.dgvUsers.Item(14, Me.dgvUsers.SelectedCells(0).RowIndex).Value.ToString()

frm.txtAddress.Text = Me.dgvUsers.Item(15, Me.dgvUsers.SelectedCells(0).RowIndex).Value.ToString()

frm.Text = "Edit User"

frm.ShowDialog()

End Sub

The Problem is that the Rad GridView doesn't recognize the RowIndex.

Can Anyone help me with a solution?

Data Bound Item

Hi !
I have a grid with some columns.
If I double click a cell I want to open a window chose some values and update the cell value. Is working fine for rows already in the table.
For new rows "Click here to add new row " is not working.
I've seen something strange.

I have this code
Dim currentRow As GridViewRowInfo = CType(sender, RadGridView).CurrentRow
if currentRow.DataBoundItem Is Nothing
do something

But even if I seen in watch screen this as having nothing value
the "do something" line is not executed .It jumps over it. Is like is a value there, even I see in watch window this currentRow.DataBoundItem = nothing.

Why is that ?
How I can access the current NEW line and modify cell values through code ?

Regards,
Mihai

[Solved] GridView CompositeFilterDescriptor no longer working

Hoping someone can help me with this. I just upgraded my WinForms controls to version 2010.3.10.1215 from 2010.3.10.1109 and my composite filters have stopped working. They do not cause an exception or break anything else, it's as if they are completely ignored. Indidual filters work perfectly still, but they are insufficient to my needs. So... I'm checking with the community before posting a ticket. Example composite filter below. Thanks

CompositeFilterDescriptor

compositeFilter = new CompositeFilterDescriptor();

compositeFilter.FilterDescriptors.Add(

new FilterDescriptor("IsDeleted", FilterOperator.IsEqualTo, false));

compositeFilter.FilterDescriptors.Add(

new FilterDescriptor("FolderLocation", FilterOperator.IsEqualTo, selectedFolder));

compositeFilter.LogicalOperator =

FilterLogicalOperator.And;

rgvEmails.FilterDescriptors.Clear();

rgvEmails.FilterDescriptors.Add(compositeFilter);

autoselect when only one item is left

hey guys

I've a problem with the filter in the MultiColumn ComboBox:

If filtering is turned on, and I type some letters in the CB that only one row is left in the combogridview, this row is autoselected from the combobox.

Is there a way to disable that function because when you type fastly you don't get when the row is autoselected. That means you write some more letters after the autoselect.

So for example if I would like to select the row "Media":

1. I type "Me"
2. only one row is left in the combogridview and the row "Media" is selected (also in the combobox.text is now "Media")
3. I dont get that and continue with "dia"
4. So in the Combobox the Text "Mediadia" appears
