How do we set the nulldate and nullvalue for the datetimecolumn in the gridview.

Following code doesn't work. Please suggest.

private void radGVMinMembers_CellBeginEdit(object sender, GridViewCellCancelEventArgs e)

{

if(e.ColumnIndex == 3)

{

    RadDateTimeEditor rdt = new RadDateTimeEditor();

    rdt.NullText =

"";

    rdt.NullValue =

new DateTime(2000, 10, 10);

    radGVMinMembers.CurrentColumn.InitializeEditor(rdt);

 }
}

Hi,

private

void radGridView1_ContextMenuOpening(object sender, ContextMenuOpeningEventArgs e)

{

if (e.ContextMenuProvider is GridHeaderCellElement)

{

e.ContextMenu =

this.columnContextMenu;

}

else if(e.ContextMenuProvider is GridDataRowElement )

{

GridDataRowElement cell = (GridDataRowElement)e.ContextMenuProvider;

e.ContextMenu =

this.contextMenu;

}

}



I want to open a context menu when user click any where on a prticular Data row.

I also wants the value of all the column in that row.

Let me know which class will be suitable as a context menu provider so that i get all the data in that row and also be able to open the contextMenu..

Povide an example if possible?


Note :- The code in the else-if part is not working properly.

How do you turn off AutoHighlighting for a RadComboBox.  When the user selects an item in the dropdown, the text is highlighted in the control.  Is there any way not to highlight the text???

How do you turn off highlighting of the rows when you just wave your mouse over the row without clicking, for the RadGridviewControl.

What do I have to do to make font size changes take effect?

Seems the size remains unchanged no matter if I change it at design time or at run time.

I tried this:
Me.RadGridView1.Font = New System.Drawing.Font("Arial", 3.0!, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, CType(0, Byte))

Compare the amount of data shown on a MS ListView control to the RadGridView control.

Also, any way to speed up loading of data. Takes about 5 times as long than loading a ListView in VB6 with the same data. 

With RadGridView1
            .GridElement.BeginUpdate()
            Dim command As OleDbCommand
            command = New OleDbCommand("SELECT * FROM FinalSettings")
            command.Connection = New OleDbConnection(My.Settings.WorkSpaceMgrConnectionString)
            command.Connection.Open()
            .MasterGridViewTemplate.LoadFrom(command.ExecuteReader())
            command.Connection.Close()
            .GridElement.EndUpdate()
End With

I entered a support ticket against Q3 2007 stating this:

I need to hide a row and keep it hidden no matter what the user does (sort, group, etc).  I can't use a filter, because I need the grouping when the user chooses to group (a filter excludes the row from the grouping).  I can hide the row using IsVisible, but the row's IsVisible is reset to true by changes to sort, sort order, grouping, etc.  Visibility settings are ignored in the RowFormatting event.

Any suggestions?

Thanks.

I received the following reply:

 Kevin,

Thank you for contacting us.

This issue has been resolved in 
RadGridView Q1 2008 Beta. Please, give it a spin and let us know what you think.

In the current stable release you should process the SortingChanged and GroupingChanged events.

Let us know, if you need further assistance.

 
Greetings,
Jack

BUT, the IsVisible is still being reset on my rows whenever the user chooses to sort or group.  Should I be using something other than IsVisible?  Did this not make the Beta release?

Thanks.

Hi, I would like to hide the overflowbutton that looks like a small arrow pointing down.  I thought setting the "showoverflowbutton" property to false would do it because setting it in design time appears to do the trick but when I run my app the arrow still shows.  Is there any way to hide it?
