ExpressionEditor bound value not updating?

Hello Telerik support,

I hav a grid which binds an (Telerik Open Access) object source. Some columns have Expression Editors:

// Attaching the datasource

radGridView2.DataSource = _activeBatch.LigdagenKlinischGefactureerds.OrderBy(c => c.RowNumber);

// Expression column definition:

GridViewTextBoxColumn b = new GridViewTextBoxColumn("B")

{

HeaderText = "B",

EnableExpressionEditor = true,

Expression = @"IIF(ISNULL(PreviousNo,"""")<>No,""nieuw"",null)"

};

When saving the datasource something strange happens. Just before do a SaveChanges I check the values of a specific row which should contain changed (evaluated) values:

radGridView2.Row[x].Cell["B"].Value = "nieuw", this is as expected for the evaluation of row X
(radGridView2.Row[x].DataBoundItem as MyBoundObject).B = null (???)

Additionally I have another question: If my datasource contains a value, the expression should not be evaluated. Is this possible? (maybe on a specific cell event?)

Kind regards,
Raoul

RadDateTimePicker BUG REPORT !!!

Hi Telerik !
There is a bug with RadDateTimePicker.

1. Set RadDateTimePicker.Culture = ar-SA (To see Arabic date)
2. Run program.
3. Open drop down calendar.
4. Open year and month drop down list.
5. Now count how many months are there. There should be 12 months, but there is 11 months.

NOTE1: I should add that when you try to reach the missing month with left or right buttons, the object stucks, or drops the missing month.
NOTE2: Sometimes you can reach to missing month with FastForward or FastRewind buttons, but then another month will be lost.

I believe it is BUG !!!

RadRibbon doesn't scale when Windows magnification set to 125% or 150%

Hi!

My application is standard WinForms Form with RadRibbonBar placed on that form. I set autoScaleMode to DPI for that form, ale unfortunately form and ribbon doesn't scale to 125 or 150%. Other forms are actually RadForms, and forms and all controls placed on themscales right. Is this have to be RadRibbonForm to scale right? Is this the only solution for my problem?

UPDATE: In fact form scales. Only ribbonbar and statusbar doesn't scale.

Cheers,
Kuba.

What is the best way to mark a selected row?

Hello,

I have a table with three fields: RowID, CustomerName and Selected. I am loading this into the gridview and I would like to programmatically select the row where Selected is true. If this was ASP.NET I would use the RowDatabound event and check the value of Selected and highlight. What is the best way here? After I load the list loop back through the data, get the one that is selected and then loop through the rows in the grid to select it? Seems like there would have to be a more efficient way of doing this.

Thanks,

Warren

Losing Focus without expanding DateTimePicker populates today's date as value

When I tab through the controls in my form, and while tabbing through datetime picker Current Date is populated as value. I do not want to the control to enter any date without user selection. Also, I have a pair of datetime picker like start date and end date and each is of the control's Opened & Leave Events are utilized as below but without these also, the same issue occurs.

private void dtProdStartDate_Leave(object sender, EventArgs e)

{

if (dtProdEndDate.Text == String.Empty && dtProdStartDate.Value != DateTime.Parse("1/1/0001"))

{

DateTime dtStart = dtProdStartDate.Value;

dtStart = dtStart.AddMonths(1);

DateTime dtEnd = dtStart.AddDays(-dtStart.Day);

dtProdEndDate.Value = dtEnd;

}

else

{

if (DateTime.Compare(dtProdStartDate.Value, dtProdEndDate.Value) > 0)

{

DateTime dtStart = dtProdStartDate.Value;

dtStart = dtStart.AddMonths(1);

DateTime dtEnd = dtStart.AddDays(-dtStart.Day);

dtProdEndDate.Value = dtEnd;

}

private void dtProdStartDate_Opened(object sender, EventArgs e)

{

if (this.dtProdStartDate.Value == DateTime.MinValue)

{

((RadDateTimePickerCalendar)this.dtProdStartDate.DateTimePickerElement.GetCurrentBehavior()).Calendar.FocusedDate = DateTime.Now;

}
