Does GridView.DataSource binding change reset column visible/layout?

I'm looking for an alternative grid that is NOT based on Microsofts VERY POOR implementation of DataGridView. The problem I'm having with the Microsoft DataGridView is summarized nicely in this YouTube Video:

http://www.youtube.com/watch?v=K-LhoDw9CmY

Basically if I set column visible and column formatting options in the designer/IDE and then during application runtime my code sets DataSource = myDataTable and then change the DataSource to another DataTable, ALL my column visible state and formatting information is reset to "default" state ... NOT good. (note: ONLY when the DataSource is changed, first time it works fine and keeps visible/formatting info).

Per video, the only work around is to add a BUNCH of code to DataBinding_Complete event to set my columns back to the state I setup via designer/IDE.

So my questions:

1. Is Telerik Grid based on the Microsoft's implementation?
2. Is this same behavior "by design" in the Telerik Grid?

Thanks, Rob.

I'm wondering if it isn't possible to add a ScreenTip to the StartButton like in Office 2007.

Please tell me how I can create a ScreenTip there, if it's possible.

ToolStrip Docking

Here is the scenario. I want to use a tool strip to have 10 Image buttons on one tab strip Item. I want this tab strip item to be as big as the parent container that holds it and to dynamically grow if the form gets bigger. Basically docking the tool strip item to both the top left and right. The tool strip does this, but the toolstrip item is only as big as the 10 buttons that are put in it. Is this possible using the Tool strip.

Thanks,

Don

problem with tableadapter and gridview

Can anyone tell me what's wrong with the following code. When it gets to the line of code
grdStations.DataSource = taStations.GetData(1) I get a run time error for a "login failure for User5" . The tableadapter is a call to a stored procedure, and User5 has permissions to execute the procedure. Any help would be appreciated.

Thanks
Tom

Private Sub LoadStationGrid()
       Dim taStations As New stationsTableAdapters.GetStationsByDeptTableAdapter
        Dim dsTrucks As New stationsTableAdapters.TruckTableAdapter

        grdStations.DataSource = taStations.GetData(1)

        Dim template As GridViewTemplate = New GridViewTemplate
        template.DataSource = dsTrucks.GetData()
        grdStations.MasterGridViewTemplate.ChildGridViewTemplates.Add(template)

        Dim relation As GridViewRelation = New GridViewRelation(grdStations.MasterGridViewTemplate)
        relation.ChildTemplate = template
        relation.RelationName = "StationTrucks"
        relation.ParentColumnNames.Add("sID")
        relation.ChildColumnNames.Add("StationID")
        grdStations.Relations.Add(relation)


    End Sub

Overwriting MaskedEditBox text

Another MaskedEditBox question...is the following behavior by design, and if so is there a hack I can employ to stop it:

I have a MaskedEditBox set up with the mask of "(###) ###-####". I enter "(800) 555-1212" in the control. I select all of the text and attempt to type over it to enter a new number. Nothing happens. I have to select the text, delete it, then type again or overwrite one character at a time.

I would like to be able to select the text and begin typing to overwrite it, as with a normal textbox.

ItemClick

Hello
i got this situation:
i have a textbox and a combo, i filled the combo in the form_load event
the combo properties:
DisplayMember = "Test1"
ValueMember = "Test2"

i want when i choose a item in the combo the textbox get the SelectedValue but
the problem with SelectedIndexChanged or SelectedValueChanged event, is this events fires even when i filled the combo
there are any event like ItemClick or else that only fires when you click on an item not every time you filled the combo?

if you have a query under this events, the query will be executed even if you don't want to
and this will affect the performance of your application because if you need to update the combo values often
the event will fire again and again

any help
thanks

P.S.
Sorry about my english, is not good enough

Disable Combobox based on a condition

Hi Telerik team,

I have a scenario where in my gridview i need to show up combox for some cells and hide them for some other cells based on a
condition.

I tried this using Cell_formatting event using the following code but it doesnt seem to work fine.

private void radGridView2_CellFormatting(object sender, CellFormattingEventArgs e)

{

if (e.CellElement.ColumnInfo.HeaderText == "Amount" && customers.ToList<Customer>()[e.CellElement.RowIndex].Amount < 10 )

{

check =

true;

}

if

(this.radGridView2.Columns[e.CellElement.ColumnIndex].UniqueName == "Type1")

{

if (check)

{

((Telerik.WinControls.UI.

GridComboBoxCellElement)(e.CellElement)).Visibility = ElementVisibility.Hidden;

check =

false;

}

Here check is a class level boolean variable and I have a customer collection with 3 properties. And the Type1 and Amount columns are dynamically added at runtime.

GridViewComboBoxColumn combo = new GridViewComboBoxColumn();

combo.HeaderText =

"Type1";

combo.UniqueName =

"Type1";

combo.DataSource =

this.BindData();

combo.DisplayMember =

"KeyValue";

combo.ValueMember =

"StringValue";

this.radGridView2.Columns.Add(combo);
