I Have very little programming knowledge. This program worked well before I got a newer version of Telerik. Now it is having trouble converting RadDropDownMenus to RadContextMenus.

mnContext = new RadDropDownMenu();

mnItem = new RadMenuItem("&Add Stats" );

mnItem.Tag = lnkToTeam;

mnItem.Name = "AddBattingStats";

mnContext.Items.Add(mnItem);

mnContext.Click += new EventHandler(tvTeam_ContextMenu_PitchPlanRootClicked);

planGroupNode.ContextMenu = mnContext;

planGroupNode.Tag = null;

planGroupNode.Name = "PitchPlanHeader";

planGroupNode.ToolTipText = "Right-click to add or delete Pitch Plans";

ContextMenu

ChartView line graph with dates displaying every day.

Hello,

I have a Cartesian line graph with dates as CategoryMembers going back 90 days. I'm trying to only display a label every 10 days so that the x-axis isn't so crowded. Is this possible?

Thanks,
John

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

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?

Regards
Erwin

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

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.
