Why isn't there support for InvokeRequired?  Standard windows components have it...can't this just be passed through?

I'm using the current version of the Winform GridView control.

Assuming I've got the grid bound to some data and some of the columns are configured to group in a nested hierarchy. Is it possible to make one of the grouped rows the currentl row via code?

Thanks

Hi,
My issue is...when we right click on any row  have to create customized  right click drop down  menu instead of the default options having copy,Edit,sorting,Conditional formatting...etc.. and also have to customize the corresponding events.

Helpful for me if you can give me detailed description.

Thank you in advance..

I am in need of a databound checkboxlist.

I need to display a dynamic list of options that a user can select, and they must be checkboxes because the user can select multiple items.

for now i am having to use a RadGrid to accomplish a hacked way to do this.

This is a serious issue, we are currently unable to deploy our application due to an apparent issue with RadTreeView embedded in a RadPanel.

We have no customization on the TreeView, and everything looks fine in the designer. When we run the application, we get the following exception:

'-1' is not a valid value for 'LargeChange'

 at Telerik.WinControls.UI.RadScrollBarElement.set_LargeChange(Int32 value)\r\n   at Telerik.WinControls.UI.RadScrollBar.set_LargeChange(Int32 value)\r\n   at Telerik.WinControls.UI.RadTreeView.OnLayout(LayoutEventArgs args)\r\n   at System.Windows.Forms.Control.PerformLayout(LayoutEventArgs args)\r\n   at System.Windows.Forms.Control.PerformLayout()\r\n   at Telerik.WinControls.UI.RadTreeView.InvalidateLayout()\r\n   at Telerik.WinControls.UI.RadTreeView.sizeChangingTimer_Tick(Object sender, EventArgs e)\r\n   at System.Windows.Forms.Timer.OnTick(EventArgs e)\r\n   at System.Windows.Forms.Timer.TimerNativeWindow.WndProc(Message& m)\r\n   at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)\r\n   at System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW(MSG& msg)\r\n   at System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop(Int32 dwComponentID, Int32 reason, Int32 pvLoopData)\r\n   at System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context)\r\n   at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context)


It provides a line-number, but this code appears to be auto-generated from your theme files, or something to that effect, because the line# in the designer file shows no reference to setting the 'LargeChange' value on the treeview.


Please, any help you can provide is vital at this point, our application is not deliverable due to this error, and we see no method to work around this problem!

Thanks.

A useful control to send information to the user, like the alert of the email.

I found similar control here : 

http://www.infragistics.com/dotnet/netadvantage/winforms/windesktopalert.aspx

it 's a very professional and beautiful way to show information, error about the problem for many events.

If i create  GridViewLookUpColumn from designer then create this code in intializeComponent. When i run, do not show column.
if i create like telerik example in form constructor  then run ok.

Same code in two places not same run.

Telerik.WinControls.UI.

GridViewLookUpColumn gridViewLookUpColumn1 = new Telerik.WinControls.UI.GridViewLookUpColumn();

gridViewLookUpColumn1.HeaderText =

"Grupo";

gridViewLookUpColumn1.Width = 150;

gridViewLookUpColumn1.FieldName =

"CodGrupoBaremo";

gridViewLookUpColumn1.DataSource =

this.grupoBaremoBindingSource;

gridViewLookUpColumn1.ValueMember =

"CodGrupoBaremo";

gridViewLookUpColumn1.DisplayMember =

"DescripcionGrupo";

this

.elementoBaremoRadGridView.MasterGridViewTemplate.Columns.Add(gridViewLookUpColumn1);

I have a GridView that's bound do a BindingList.  No rows show in the grid until the user clicks the header column to perform a sort.  Any idea why the rows don't display until the user clicks the column headers?

Using Q1 2008 release.

I am experiencing a problem with the radCalendar control in that when I want to unselect a selected date, the only way that I can get it to unselect is to click on the one i want to remove and then click on any other date, which effectivley selects the new date, and is not preferred.

I want to be able to simply unselect a date by clicking on it, and i do NOT expect to have to write code to do it. It does not work in single select mode or multiselect mode.

to see an example of what i am describing, you can look no further than the Telerik control demo project that is installed with the product.

From the Demo app choose RadCalender, and the Selection Demo. With Allow Multiple Select enabled, click a few dates. Then simply try to unselect one of the dates that you previously selected. I tried single click, double click, ctrl click, right click, click + del, click + backspace.. etc. The only way to deselect a date is to click the date and then click some other date.

I think i am going to start charging telerik for all of the wasted time i have spent trying to figure out workarounds to these controls. Please BUGTEST the controls before releasing ANY new control sets. Get the products stable first, then add new features second, so that paying customers who have project deadlines can actually use the controls for their intended purposes rather than having to submit forum entries to hope that someone has a hack solution to a problem that other control sets do by DEFAULT!!!!!

Hi,

May I know how can I set so that the ribbon bar will not response to keyboard?

I found that, the ribbon bar might cause error while I press "CTRL".

Please advice.
