I've got a gridview with a combobox column. When I add a new row, I can chose a value from my combobox but how can I set the value of an other column depending on the value that is chosen from the combobox when I insert the new row to the gridview.

RadDropDownList in a GridView

I have a RadDropDownList in a gridview, the Value Changed Event is raised only when I increase/ Decrease the value with the arrows and not when key pressed.

I partially resolved the problem by adding the following code to the Value Changed Event:

GridSpinEditor gseditor = sender as GridSpinEditor;

if (gseditor != null)

{

this.CurrentCell.Value = gseditor.Value;

}

When I press the backspace key the event is raised except if it the last digit.
Any solution?

Thanks,
Dror

Using GridViewDecimalColumn

Hello,

In a gridview, I am using a GridViewDecimalColumn to display numeric data.

The problem is that I would like to be able to use the two arrows key (Up and Down) to scroll on my GridView, and not have my data being increased or decreased when using them. Is there a way to disable the increasing and decreasing of data when using these keys ?

If not, is there a possibility to use another column type (GridViewTextBoxColumn for example) and then, how can I manage it so only numeric values can be typed into it ?

Thank you for your help.

Batch update gridview cells value

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
