Hi,

I was wondering if any one can help me dock a RadButton to the parent container so that when the Radform is opened and the user maximizes or minimizes the screen, the RadButton will autolocate to the same location respective to the current screen size?

Thank you.

GridViewComboBoxColumn

Hello

I have two questions about the GridViewComboBoxColumn:

1. When I start editing a cell form a GridViewComboBoxColumn it always clears the currently displayed value. How can I disable that?

2. How can I change the item height of the drop down list? Is there something like the ItemHeight property of the ListElement of a RadDropDownList?

Best regards

How to reset Breadcrumb

Hi,

is it possible to reset the text of a breadcrumb (databind on treeview)?

.ResetText does not work...

A workaround could be to perform a click on the treeview programatically to get an update of the breadcrumb, but this doesn't seem to work either. I tried radtreeview.RootElement.PerformClick() without success.

A Clear-Method for the breadcrumb should be helpful for the beginning, but I didn't found one.

Best regards

Disabling Floating in Child form

I have a radform with 3 panels. The middle panel displays the initial window and any called child forms as this is the mdi parent. I found I could disable floating in each window by placing the following code:

this-object:radcenterWindow:AllowedDockState = Telerik.WinControls.UI.Docking.AllowedDockState:All and not Telerik.WinControls.UI.Docking.AllowedDockState:Floating.

How can I disable floating on any loaded child form?

define variable r-object as class Telerik.WinControls.UI.RadForm.

define variable r-program as character no-undo.
r-program = "programs.POSPRO".
r-object = dynamic-new r-program().
r-object:MDIParent = this-object.
r-object:show().

Thanks

Mark

ContextMenu custom item weird display

Hello,

I'm trying to add custom menu item to the header cells context menu but i have weird display when i am using derived class instead of RadMenuItem class directly (see attached image).

Can you explain to me what is wrong with my code ?

public class CustomOpMenuItem : RadMenuItem

{

private MyForm _form;

private int _columnIndex;

private CustomOp _op;

public CustomOpMenuItem (MyForm form, int columnIndex, CustomOp op)

{

_op = op;

switch(_op)

{

case CustomOp.CUSTOM1:

this.Text = "Custom 1";

break;

case CustomOp.CUSTOM2:

this.Text = "Custom 2";

break;

case CustomOp.CUSTOM3:

this.Text = "Custom 3";

break;

}

_columnIndex = columnIndex;

_form = form;

this.Click += onClick;

}

private void onClick(object sender, EventArgs e)

{

_form.DoCustomOp(_columnIndex,_op);

}

private void onContextMenuOpening(object sender, VirtualGridContextMenuOpeningEventArgs e)

{

for (int i = 0; i < e.ContextMenu.Items.Count; i++)

{

if (e.ContextMenu.Items[i].Text == "Pinned state")

{

// hide the Delete option from the context menu

e.ContextMenu.Items[i].Visibility = Telerik.WinControls.ElementVisibility.Collapsed;

if(i != 0)

{

// hide the separator before the Delete option

e.ContextMenu.Items[i - 1].Visibility = Telerik.WinControls.ElementVisibility.Collapsed;

}

if (e.RowIndex == RadVirtualGrid.HeaderRowIndex)

{

RadMenuSeparatorItem separator = new RadMenuSeparatorItem();

e.ContextMenu.Items.Add(separator);

RadMenuItem customMenuItem = new RadMenuItem();

customMenuItem.Text = "Custom Data Operation";

e.ContextMenu.Items.Add(customMenuItem);

e.ContextMenu.Items.Add(separator);

e.ContextMenu.Items.Add(new CustomOpMenuItem(this, e.ColumnIndex, CustomOp.CUSTOM2));

e.ContextMenu.Items.Add(separator);

e.ContextMenu.Items.Add(new CustomOpMenuItem(this, e.ColumnIndex, CustomOp.CUSTOM3));

}

Regards.
