GridViewDateTimeColumn - how to edit time AND date

Hello, I'm trying to make date and time both editable in a GridViewDateTimeColumn. I declare a column with this code:

column = new GridViewDateTimeColumn(def.Name);

string dataFormatString = (def.CustomString == null ? "yyyy-MM-dd hh:mm:ss" : def.CustomString);

((GridViewDateTimeColumn)column).EditorType = GridViewDateTimeEditorType.TimePicker;

((GridViewDateTimeColumn)column).FormatString = dataFormatString;

((GridViewDateTimeColumn)column).CustomFormat = dataFormatString;

I tried DateTimePicker and TimePicker alike.

In DateTimePicker the time is always 12:00. If I want to edit the field with keyboard only (no additional window) I only see the date in the editbox, the time vanishes on edit mode. In TimePicker I can edit date in edit mode.

My questions are:
1) How to make time editable in DateTimePicker?
2) Is there a WinForms control that allows editing date and time in additional window mode?

Thank you in advance for your answers.
Best wishes,
Mariusz

Default Theme Font 2010 Q1 SP2 (Segoe vs. MS Sans Serif)

Hi,

I notice you have changed the font to Segoe. My user Base is still mainly Windows XP. Is there a safe fallback built in in the Theming Mechanism?
What's the best way to configure MS Sans Serif as the Font throughout if the App is not on Vista/Windows 7, Even if Segoe UI is installed with Office 2007?

Regards
Erwin

Please let us know the fix for this.

Attached is the screenshot for that.

As we are in production, we would appreciate your immediate response.

[Solved] Close TabStrip Tab item by pressing the middle mouse button

Hello,

I have a number of tabs within a radpageview control in tabstrip mode, and I would like to allow the user to close them by pressing the middle mouse button (like a regular web browser).

This is what I've done so far:

//add event handler

newPage.Item.MouseDown += new MouseEventHandler(radButtonItem_MouseDown);

and the function:

private void radButtonItem_MouseDown(object sender, MouseEventArgs e)

{

//button was clicked by the mouse

if (e.Button == MouseButtons.Middle)

{

MessageBox.Show("Middle button");

rpvApplication.Pages.Remove(((RadPageViewStripItem)sender).Page); // crashes!

//rpvApplication.Pages.RemoveAt(3); // crashes!

}

I've tried calling the Pages.Remove function using the sender object as well as by the tab's index, but the result is always the same:
"nullreference exception" right after the page is removed.

Is there another way I can execute the 'close tab' functionality (just like clicking the 'x' button), without getting a null reference exception?

Thanks in advance!

Determine if the grid has errors

I have code in the CellValidating event that sets ErrorText to display errors.

If the user then clicks the Save button, i'd like to display a message saying "Gotta fix those errors first".

Is there a way to ask the grid if it has any errors? Or do I need to loop through every cell and check its errortext?

Thanks!

Deployment after 2012.2.726.40

Hello folks,

I have a Winforms app that is compiled in .NET 4.0 deployed using click once fine before upgrade. Post upgrade to 2012.2.726.40 winforms controls I now get an error that the client needs to have 2012.2.726.20 installed in the GAC. The only reference that i can find that is using this .20 version is Quickstart.dll. I have set all Telerik Dlls as include under application files as well as Quickstart.

If removed other controls complain and cause numerous compile time errors.

Any assistance is greatly appreciated.

After setting a different cell-Background, rows are not "highlighted" after selecting them!?

Hello!

In my GridView, I'm alternating the background-color from transparent to some color for "columns-blocks". This is working.

Now, when I select a row, I want the whole row be higlighted in the typical orange color. After selecting another color, the "columns-blocks" should alternate again for the disselected row.

To better understand what I mean, a attached a screenshot.

Kind regards

Michael
