Hi,
When I set in RadListView "VerticalScrollState" to "AlwaysHide", kinetic scrolling doesn't work and mouse wheel scrolling doesn't work. I don't want to see scroll bar and I want to hide it. And also "VerticalScroll.Visible = false" doesn't work.
Best regards.

I am using your date time picker control with the latest version of the win form controls 2013.3.1016.20

I have the control property ShowUpDown = True

my code is

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles Me.Load
   RadDateTimePicker1.MinDate = New Date(1890, 1, 1)
   RadDateTimePicker1.NullDate = New Date(1890, 1, 1)
   RadDateTimePicker1.NullableValue = Nothing ' New Date(1890, 1, 1)
end sub

under my clear button I have

RadDateTimePicker1.Value = New Date(1890, 1, 1)
RadDateTimePicker1.SetToNullValue()


this whole process of clearing the date seems way to excessive, i took me forever to find you had to set the minDate to the null value date to get this to work at all.
I would expect to be able to clear the control by writing
RadDateTimePicker1.value = nothing
This would be simple, easy and intuitive

Besides that the problem i am having is when the control first loads it shows as blank
if i press the up or down arrow it shows the current date time
when i press my clear button it does clear the control.
but if i then click in the control and then click another control so it loses focus the current date time that appeared after pressing the up or down button comes back and is displayed in the control, and no matter what i try i can not stop it coming back when the control gets and then loses the focus again.

please help, I have spent way to long trying to make this seeming simple vital functionality work correctly

Hi Telerik,


I was wondering on how to use the RadPageViewPage in combination with controls. I was looking for an item list within the RadPageViewPage to add buttons (or other controls) to the Page. But I can't seem to find it (wondering if it actually exists). How should this RadPageViewPage be used? Should I just add normal controls to it from the VS toolbox?



Would be nice to have a items list in this control to add buttons to it. This was the case with the previous version of the OutlookBar if I recall correctly.



Thanks for your information.



Best Regards,

Francois

Hi Telerik,

I use a radGridviews to implement a system which supports downloading files from IIS server.

The column setting is shown below,
<telerik:GridHyperLinkColumn DataTextField="File Name" HeaderText="File Name" UniqueName="File Name" DataNavigateUrlFormatString="IIS_ItemServer\{0}" DataNavigateUrlFields="File Path" />

In addition to downloading files,

is it possible to implement to trigger an extra event/function when clicking the file links by this way?

Thanks you

Hello,

I have a GridView on which I want to set programmatically the CurrentCell. I have found a solution using this metohd 

public void SetCurrentCell(int rowIndex, string columnName)
{
     CurrentRow = Rows[rowIndex];
     CurrentColumn = Columns[columnName];
}

But using this method fires twice the CurrentCellChanged event which it is not desirable.
Is there other way to do this to simulate the Mouse Click which does not fire twice the CurrentCellChanged?

Thanks in advance

Hello!

I have RadGridView bounded with DataSet. Is there any way to change type of the columns?

For example I have DataTable in DataSet with columns: Id, Name and Job. I'm creating data binding between RadGridView
and DataSet. I would like to have three columns in my RadGridView: Id (typeof DecimalColumn), Name (typeof TextBoxColumn), Job (typeof MultiComboBoxColumn). I know that I have to have Id as System.Int32, Name as System.String in  my DataSet, but how can I change Job into MultiComboBoxColumn?

Thanks for help, Kuba

Hello Support,
I have to bind a large of data to GanttView (6000 Items, and 12000 links). After binding data, Memory is about 200MB. And In GUI, when  I were scrolling down form top to bottom Items, I found that the memory for the application increase so much about 1.5GB.
