is there a way to batch update cell value of a gridview.

I have a situation where i have to loop thru each row and then update one cell value, as shown below. But it becomes really slow when i have large number of records on the grid, so is there any batch update that can be applied. My interface is with a textbox field above the grid and when the user enter text and press apply it has to apply that text to all records on the grid (it could be 100 - 10000 reocords on the grid depending one the search)

foreach (GridViewRowInfo row in radGV_.Rows)

{

row.Cells["BName"].Value = txtBName.Text;

}

RadStatusStrip disable resizing

Hello!

I'm using the RadControls 2011Q2 and I want to disable the ability to resize the Form with the RadStatusStrip. I have already disabled the SizingGrip, though I can resize the Form.

Is there a way using the StatusStrip and the window can only be resized as normal Form-behavior?

Kind regards
Juergen

Different data source for different Combobox rows

I have a grid view in which I want to customize the combobox entries for a given row depending on user selection of another combobox entry in the row. Different rows would have different data sources. Is this possible, and if so, can you tell me how to do it?

Thanks.

checking all CheckBox columns in a grid

Hi all,

I have a problem checking all checkbox columns in a grid. I used the next code:

Me.mygrid.GridElement.BeginUpdate()
For Each row As Telerik.WinControls.UI.GridViewRowInfo In Me.mygrid.Rows
row.Cells("Checked").Value = True
Next row
Me.mygrid.GridElement.EndUpdate()

It works well, but if the grid is sorted by some column the same code is so slow...

The datatable contains about 15.000 items. is that the problem?

Transparency of Dock

Hi,

I'm using Q2 2009 SP1. I want to be able to set my RadDock background to Transparent so that the BackgroundImage of the host Form can show through it. I have used the sample code elsewhere in the thread to do this;

    
            this.radDock1.MainDocumentContainer.BackColor = Color.Transparent;  
        
                        Telerik.WinControls.RadElement el = this.radDock1.MainDocumentContainer.RootElement.Children[0].Children[0];  
        
                        (el as Telerik.WinControls.Primitives.FillPrimitive).BackColor = this.BackColor;

but I have a couple of problems with this;
1) It picks up the BackColor of the Form but isn't truly transparent (the form's Background Image does not show through). I've tried placing a Picture box with the image on the Form, docked, and at the back of the Z Order, but again the Dock picks up the backcolour of the form, not the graphic immediately behind it.
2) I want to be able to set the individual DocumentWindow items in the RadDock so that they gradually "fade out" - the tabs being fully opaque and gradually fading to transparent until by the time they get to the bottom they are fully transparent. The reason for this is that the Dock and TabStrip is quite an "intrusive" control and seems (to me) to dominate the user interface once its been put there - I'd like to be able to make it blend into the background once the important bit (the actual tabs) are visible to the user.

Can you help ?

AppointmentEditDialog - show without using context menu

Hi,

I wonder if it is possible to show the editappointment dialog programatically, i.e. not via the built-in context menu?

The dialog should show based on the selection in the scheduler, i.e. the same way as the context menu command does.

The reason why I'm asking is that I want to show the dialog through a separate toolbar command.

Thanks in advance,
Johan

RadCheckBox

Hello,

I've seen a number of posts that explain how to highlight buttons, combos, etc using the Enter and Leave events.

I would like to do the same thing with the RadCheckBox. I've tried changing the BackColor of the ButtonElement, TextElement, etc but with no luck.

How do I accomplish this ?

Thanks,
Chet

Get Default Text for GirdViewCommandColumn

I have 3 GridViewCommandColumn in my radGridView. I need to determine which one of the three command columns were pressed. I can't seem to figure out how to get the "Default Text" value to determine which command column was clicked. I can get the value of the command column by the CommandCellClick event but I can not get the "Default Text" value. My three default text values of the three command columns are "Time Sheet", "Print Monthly", and "Registration". Thanks for any help you can provide. New at WinForms!

Private Sub RadGridView1_CommandCellClick(sender As Object, e As System.EventArgs) Handles RadGridView1.CommandCellClick

Dim gcce As GridCommandCellElement = TryCast(sender, GridCommandCellElement)

'GridViewCommandColumn

If gcce Is Nothing OrElse gcce.Value Is Nothing Then

Return

End If

MessageBox.Show(gcce.Value.ToString())

End Sub
