Hi Dess
Issue resolved. Which event Radcombobox has like got focus or Lost focus.
When user press tab or enter key focus from Radcombobox shift to another control say like multicolumncombox or radtextbox

I would like to note that Telerik UI for WinForms suite offers RadDropDownList (released back in 2010), not a RadComboBox. Could you please specify what is the exact version that you are currently using since the RadComboBox control has not been available in the suite for e very long time?
RadDropDownList should be used instead. The following video also demonstrates how to switch from using RadComboBox to RadDropDownList:

Hi Dess
Sorry to inform you I am using RadDropDownList but call this dropdownlist as combobox. I used to develop software in vb6 so I call dropdownlist as combobox. I have not seen gotfocus or lostfocus event in RadDropDownList. so i use enter and leave event in RadDropDownList.
Regards
Similar to all RadControls, RadDropDownList also offers the GotFocus and LostFocus events. Please refer to the below code snippet demonstrating how to show the drop down when the control is focused after Tab key:
public RadForm1()
{
InitializeComponent();
this.radDropDownList1.GotFocus += RadDropDownList1_GotFocus;
this.radDropDownList1.LostFocus += RadDropDownList1_LostFocus;
}
private void RadDropDownList1_LostFocus(object sender, EventArgs e)
{
Console.WriteLine("LoastFocus");
}
private void RadDropDownList1_GotFocus(object sender, EventArgs e)
{
this.radDropDownList1.ShowDropDown();
Console.WriteLine();
}

Hello, Nandan,
Once RadMultiColumnComboBox is opened, the up/down arrow keys moves the selection accordingly. Then, pressing Enter will confirm the selection and close the drop down:
This is the default behavior. Are you experiencing any different behavior compared to the illustrated one?

Hi Dess
Yes up/down arrow keys moves the selection accordingly. Then, pressing Enter will confirm the selection and close the drop down. Same thing i want but not working i have to use mouse to select.
I will explain you briefly
According to Bag type (Bag, Voucher) related RadMultiColumnComboBox fill accordingly if i choose 'MEB0001' respected value should enter in text boxes like finewt in txtfinewt.text like that. It work when i use mouse to select it. I want default behavior.
here is my sample code
Private Sub mccmbStock_SelectedIndexChanged(sender As Object, e As EventArgs) Handles mccmbStock.SelectedIndexChanged
Dim dtRowCount As DataTable = CType(mccmbStock.DataSource, DataTable)
If dtRowCount.Rows.Count > 0 And cmbItemType.Text.Trim = "Bags" Then
txtFineWt.Tag = CType(mccmbStock.DataSource, DataTable).Rows(mccmbStock.SelectedIndex).Item("IssueId").ToString()
txtItemName.Tag = CType(mccmbStock.DataSource, DataTable).Rows(mccmbStock.SelectedIndex).Item("ItemId").ToString()
txtItemName.Text = CType(mccmbStock.DataSource, DataTable).Rows(mccmbStock.SelectedIndex).Item("ItemName").ToString()
txtRequired.Text = CType(mccmbStock.DataSource, DataTable).Rows(mccmbStock.SelectedIndex).Item("ReportPr").ToString()
txtGrossWt.Text = CType(mccmbStock.DataSource, DataTable).Rows(mccmbStock.SelectedIndex).Item("BalanceWt").ToString()
txtGrossWt.Focus()
txtGrossWt.SelectAll()
ElseIf dtRowCount.Rows.Count > 0 And cmbItemType.Text.Trim = "Voucher" Then
txtItemName.Tag = CType(mccmbStock.DataSource, DataTable).Rows(mccmbStock.SelectedIndex).Item("ItemId").ToString()
txtItemName.Text = CType(mccmbStock.DataSource, DataTable).Rows(mccmbStock.SelectedIndex).Item("ItemName").ToString()
txtRequired.Text = CType(mccmbStock.DataSource, DataTable).Rows(mccmbStock.SelectedIndex).Item("ReceivePr").ToString()
txtGrossWt.Text = CType(mccmbStock.DataSource, DataTable).Rows(mccmbStock.SelectedIndex).Item("BalanceWt").ToString()
txtFineWt.Text = CType(mccmbStock.DataSource, DataTable).Rows(mccmbStock.SelectedIndex).Item("FineWt").ToString()
txtFineWt.Tag = CType(mccmbStock.DataSource, DataTable).Rows(mccmbStock.SelectedIndex).Item("IssueId").ToString()
txtGrossWt.Focus()
txtGrossWt.SelectAll()
ElseIf dtRowCount.Rows.Count > 0 And cmbItemType.Text.Trim = "Lot Add. Stock" Then
txtFineWt.Tag = CType(mccmbStock.DataSource, DataTable).Rows(mccmbStock.SelectedIndex).Item("IssueId").ToString()
txtItemName.Tag = CType(mccmbStock.DataSource, DataTable).Rows(mccmbStock.SelectedIndex).Item("ItemId").ToString()
txtItemName.Text = CType(mccmbStock.DataSource, DataTable).Rows(mccmbStock.SelectedIndex).Item("ItemName").ToString()
txtRequired.Text = CType(mccmbStock.DataSource, DataTable).Rows(mccmbStock.SelectedIndex).Item("ReceivePr").ToString()
txtGrossWt.Text = CType(mccmbStock.DataSource, DataTable).Rows(mccmbStock.SelectedIndex).Item("BalanceWt").ToString()
txtGrossWt.Focus()
txtGrossWt.SelectAll()
End If
End Sub
Private Sub mccmbStock_Enter(sender As Object, e As EventArgs) Handles mccmbStock.Enter
If cmbItemType.SelectedIndex = 0 Then
fillStockDetails("Bags")
ElseIf cmbItemType.SelectedIndex = 1 Then
fillStockDetails("Voucher")
ElseIf cmbItemType.SelectedIndex = 2 Then
fillStockDetails("Lot Add. Stock")
End If
mccmbStock.DropDownStyle = RadDropDownStyle.DropDownList
End If
End Sub
i am attaching screenshot for same
Note that if you click a row that is already selected/current in the popup grid, the SelectedIndexChanged event wouldn't be fired because in this case the selection remains the same. Hence, the respective data wouldn't be filled in the text boxes.
I would recommend you to handle the EditorControl.CellClick and detect which row is clicked. Then, extract the relevant information from the GridViewCellEventArgs.Row.Cells collection and populate the controls.
this.radMultiColumnComboBox1.EditorControl.CellClick += EditorControl_CellClick;
private void EditorControl_CellClick(object sender, GridViewCellEventArgs e)
{
Console.WriteLine(e.Row.Cells["ProductName"].Value);
}
