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.

It would be nice to have a rich text editor for Winforms like you have for the Ajax controls.

If I set a top-padding value to the TreeView the D&D doesn't work.. it seems to get node the Y without padding substraction..

Is it a bug?

Thank you!

I have downloaded the latest rad controls for winforms, I have visual studio 2008 running on windows vista ultimate. I have a problem in visual studio in the designer, when i drag a new rad menu onto my form there seems to be no problem. I added a couple of items into the menu and then i ran the application,
when the application shows up in runtime the menu is gone. Also if in the designer i close the form and reopen the menu is gone as well. I have tried uninstalling and installing a new version of rad controls with the same results... All the other controls seem to work fine, except the radMenu.

If anyone can help, it is very much appreciated.

May I know how can we convert the shaped Form into RadForm? As what we noticed, if we direct change the inherits text, then it will cause error.

I have a form with a combobox which has some values entered during design-time.  I also have a datagridview.  I'm trying to convert this so I am using RadControls combobox and gridview.

Here is my working code using built in controls:

    Private Sub CustomerBindingSource_CurrentChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CustomerBindingSource.CurrentChanged
        Me.customerID = CType(Me.CustomerBindingSource.Current, DataRowView).Row.Item("CustomerID")
        filldgvCustomerVariousData(Me.customerID, Me.ComboBox1.SelectedItem)
    End Sub

Here is my attempted code using RadControls:

        Dim item As RadComboBoxItem = TryCast(rcbo_ShowTransactions.SelectedItem, RadComboBoxItem)
        Me.customerID = CType(Me.CustomerBindingSource.Current, DataRowView).Row.Item("CustomerID")
        filldgvCustomerVariousData(Me.customerID, item.Text)

The above code will work, but only after I get errors saying that the value of selecteditem is Null and if I Step Over and then go select a value in the RadComboBox. 

This is probably true because the form has not yet completely loaded so I have not yet selected an item.  But I do have some default text in the RadComboBox.  So, maybe SelectedItem isn't the right thing to be using.  Is there something else I can try?

Thanks!

I am having an odd problem with the Dock manager.

I created a project similiar to the Dock for MDI example.

My version loads a form which also includes another dock manager.

This works fine and looks awesome! but, for some reason, if I close the document that contains the sub dockmanager, and then I close my application, I get this error:


If I dont close any of the documents and just close the application, I dont get this error.


I am not sure what the actual cause is... There isnt much code going on, just alot of layout stuff.

There is a grid which is inside sub form / dockmanager.  I can see it mentions something about it in the error but I just cant figure it out, something about styling.
