How to change selected row if another row is selected

Hello,

I have a multicolumn combo box that I can't seem to set the value. When the selectindex is fired for this combobox I do a check of the data the user has worked with. If there is a missing value I pop up a message box which works but i'm unable to reset the selected value to something else. It keeps the selected value the user set to notify the group that they are finished with this job. Since there was an error I want to reset the combobox to a different value. I've tried so many things but nothing seems to work. Here is a few of the things I tried.

cbStatus.ValueMember = "value";

cbStatus.DataSource = GetStatusCodes(); //Gets data from a data table

cbStatus.AutoSizeDropDownToBestFit = true;

//Binding

cbStatus.DataBindings.Clear();

cbStatus.DataBindings.Add("SelectedValue", bs, "status");

//I've tried all the below code and it doesn't change my combox selected row or value

//((RadGridView)this.cbStatus.EditorControl).Rows[2].IsSelected = true;

//((RadGridView)this.cbStatus.EditorControl).CurrentColumn = ((RadGridView)this.cbStatus.EditorControl).Columns[0];

//((DataTable)bs.DataSource).Rows[bs.Position]["status"] = "02";

///cbStatus.SelectedIndex = 2;

When I add a watch on the below lines I get "01" and "Complete". It should change to "02" and "Working"

((RadGridView)this.cbStatus.EditorControl).CurrentRow.Cells[0].Value "01" object {string}

((RadGridView)this.cbStatus.EditorControl).CurrentRow.Cells[1].Value "Complete" object {string}

Selectedpage dont work

Hello,

i have following forms:

Dialogform: Is a form with a PageView - the Pageview have 2 Pages in it. Page A and Page B.

Mainform: From here i'm opening the Dialogform. There are 2 Buttons - on Click the button shows the Dialogform as a Dialog (modal).

Button A: On click i want to show the Dialogform. Page A should be shown.
Button B: On click i also want to show the Dialogform but Page B should be shown.

So when i'm starting my programm and i try the Buttons for the first time, everything works fine (with PageSelected).

But when i'm clicking first Button A, then closing the Diaglogform and press Button B, it still show's me Page A. The selected Tab is the right one - Tab B is marked, but it still shows me the content from Page A.
After that i need to switch manually in the Dialogform to Page A and then back to Page B, then it shows me the right Page.

Meanwhile i found a solution, but i dont know if this is the right one. I need to dispose the Dialogform on closing and then it works fine.

Is there any other solution for this issue?

Thanks.
Shaggy

[Solved] Show Hourglass Pointer on lengthy operations

With large grids (>100'000 rows) sorting columns can take a lot of time, would be nice if the Grid would show the HourGlass Pointer during such internal operations.
Is there a way I can enable this?

[Solved] Default Context Menu

This might be a stupid question but I've been trying to figure this out for hours now.

How do I enable the default Context Menu with Copy, Paste, etc. like the ones on the demos without explicitly adding those options in code behind to the menu???
My AllowCellContextMenu is set to true, but nothing shows on right click.
I also have another form that somebody else here programmed and in the ContextMenuOpening event one grid has a Copy option already there and another grid has nothing, both have AllowCellContextMenu set to true and none of them have any code for adding items to context menu...

Please help,

Thanks

[Solved] RowSourceNeeded and Sort

Hello,
I have a hierarchal grid view which uses the RowSourceNeeded event to fill the master template's child template when a row is expanded (works like a champ). The child template contains its own child template which is also filled during this event. My question is, why does a column sort fire the RowSourceNeeded event? If this is by design is there a way to defeat this functionality as it requires the two child templates to be re-filled unnecessarily (for each expanded row in my grid - ouch)? Thanks.

RadTitle bar and themes

Hello,

Winforms.

I have an application whereby I am creating a pop up window with a new rad form. My first dilemma was when I applied themes globally and I use the "Aqua" theme, I need to get the text to align left with the form set at FixedDialog.
I then started adding a RadTitle bar which sort of resolved the problem, however when I applied the "Aqua" theme and any other theme I lost the pop up border as seen in image and here are some settings in the load event

this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;

this.MaximizeBox = false;

this.MinimizeBox = false;

Size = new Size(422, 433);

Assistant.CenterFormOnScreen(this);

this.Text = "Aqua Theme";

Also not the circle on the left is gray and the Aqua theme makes it red with an x when you mouse over it.

Now when I set the settings in the form load to change the form border and I get two titles in the form.

this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedDialog;

this.MaximizeBox = false;

this.MinimizeBox = false;

Size = new Size(422, 433);

Assistant.CenterFormOnScreen(this);

this.Text = "Aqua Theme";

It is an MDI application and these are pop up forms.
Can someone tell me if this is normal or what other settings am I missing.

Thanks
