Hi -

I have a RadDateTimePicker column in my grid that is initially null. So I am calling SetToNullValue.

But when the user opens the RadDateTimePicker, we would like to set a default date. It appears to use the MinDate for the default date, which my user's don't like.

For example, for a search feature the system defaults to no date criteria (a null value date). But the user can search up to 3 months back (.MinDate = Today.AddMonths(-3)) But the user's don't want to default to this date when the calendar opens.

So is there an easy way to set a default date in this case?

Thanks!

[Solved] Upgrade to Q3 2010 : CellFormatting problem

Hello,

I have upgraded Telerik for Winforms to version Q3 2010 (version 2010.3.10.1109) .
In the _CellFormatting-event I add a RadComboBoxElement to a cell.
Since new version the event behaves strange or different.
e.CellElement.RowIndex is always -1 ?

void gridPositionen_CellFormatting(object sender, CellFormattingEventArgs e)

if (e.CellElement.ColumnInfo is GridViewDataColumn && ((GridViewDataColumn)e.CellElement.ColumnInfo).Name == "Me_Dropdown")

{

if (e.CellElement.Children.Count > 0 || e.CellElement.RowIndex<0)//the comboxbox is already added to cell

return;

//NEVER GETS HERE !!!! e.CellElement.RowIndex is always -1

RadComboBoxElement element = new RadComboBoxElement();

e.CellElement.Children.Add(element);

....

How do I get the RowIndex in the CellFormatting-event ? Or is there a new way to add a RadComboBoxElement to a cell ?
