Hello,
I'm facing a pretty strange behavior when unpinning a column in a RadVirtualGrid:
1. Pin (left or right) 1st column
2. Scroll horizontally (to not display 2nd column)
3. Unpin 1st column
4. Scroll horizontally to display 1st column
=> 1st column is hidden, the only way to make it visible is to resize a column or the entire window
It seems to be a bug and I'm trying some workaround:
- Is there a way to force refresh the grid ? (RadVirtualGrid.TableElement.SynchronizeRows is not working in this case)
- Is there an event that can be captured on column pinned state change, in order to force a refresh at this time ?
Regards.

I am building an Winforms application where the user can select his interface language (en, fr) I managed to translate about all items but not the grid column header texts.
Is there a way to load the column headers from a resource file ? Or how should it be done ?
Thanks in advance

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.

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

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

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

Dear forum,
I would like to know if it is possible to change the background color of the ActionButton of a RadSplitButtonElement when it is pressed (not expanded).
Any help is appreciated

Hello,
I was wondering if there is a way to know when the fire of CellValueNeeded event will end ? Like is there a way to know the cells row and column range on which the update/synchronize will be done ?
Hoping my question is understandable :)

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)); }}
