[Solved] Can't clear value using contextMenu for dateTime column with timePicker editor

Hi,

I defined in two different grids two DateTimeColumn with timePicker editor . In the first column I have in the column ContextMenu the clear value option while in the other column I don't.
What I am trying to do is letting the user clear the time cell after he filled it by mistake (if he prefers to leave it empty).
Let me know what I am doing wrong .... is it better way to do this ?

// with clear value option

var timeOnlyColumn = new GridViewDateTimeColumn

{

HeaderText = "Time in",

Name = Data.cJobCardData.JobCardColumns.DateTimeIn,

FieldName = Data.cJobCardData.JobCardColumns.DateTimeIn,

Format = DateTimePickerFormat.Time,

EditorType = GridViewDateTimeEditorType.TimePicker,

FormatString = "{0: h:mm tt}",

TextAlignment = ContentAlignment.MiddleCenter,

Width = colWidth

};

// No clear value option

var dateColumnIn = new GridViewDateTimeColumn

{

HeaderText = "Date Time In",

Name = Data.cJobCardData.JobCardColumns.DateTimeIn,

FieldName = Data.cJobCardData.JobCardColumns.DateTimeIn,

Format = DateTimePickerFormat.Long,

EditorType = GridViewDateTimeEditorType.TimePicker,

FormatString = "{0: M/d/yyyy h:mm tt}",

TextAlignment = ContentAlignment.MiddleCenter,

Width = colWidth

};

Multiple Displays

When my app opens, it always opens on the monitor that currently has my mouse cursor.

I have tried to specifically set the current form's Left property to a number that is smaller than the width of my left-most display, but it seems to always use the coordinates of the mouse' current display.

How can I force a form to open on a specific display?

AutoCompleteBox: Different color boxes

Hey Telerik!

How would I customize the boxes in a AutoCompleteBox to be different colors? A simple idea would be to have a list of objects with a text property and color property. The boxes could be a certain color based off the color property.

Thanks

Resizing elements

Hi,

I'm struggling with your Visual Style Builder. I'm trying to reduce the size of the Scheduler Navigator
Both the buttons and the panel where the dates are viewed. But when i look at this in the VSB, i cannot figure out where the control size is set. Neither where the element sizes is set ( i do look at the elements min and max size, padding and margin.. )

And how do i change the look of an Appointment in the scheduler - monthly view?

Could someone please guide me. I need to do this on the Pages control as well. I use the default theme as the base theme...

Regards
Svein Thomas

€ character

Hello everyone,

i'm using some RadRichTextBoxes in my application.

Because we're in the European Union, we need the character "€" for currency values like "110,23€".

But for me and my customers, it's not possible to insert a € character into the TextBoxes with the key shortcuts "Ctrl+Alt+E" or "AltGr+E" (which are the standard for inserting € characters on european keyboard layouts).

How can i modify the behaviour of the TextBoxes so that these standard values are accepted? But i think a cleaner and better solution would be a native support for the € character by Telerik itself because it's a standard character in Europe like the $ character in the US.

Regards,
Michael

[Solved] TreeView will not update after DataSource has been set to null

When using an object-relational binding with the TreeView control, if the DataSource is set to something, set to null and then set to something again the tree will no longer update.

Here is a code sample:

1. Click Load - the base data appears in the tree.
2. Click Add - a new node appear in the tree.
3. Click Clear - all nodes are erased.
4. Click Load - base data is added back in and appears
5. Click Add - nothing happens...

public partial class Form1 : Form

{

BindingList<Thing> RootChildren;

int currentId = 1;

public Form1()

{

InitializeComponent();

}

private void buttonLoad_Click(object sender, EventArgs e)

{

radTreeView1.DataSource = null;

RootChildren = new BindingList<Thing>();

Thing t1 = new Thing(1, "One");

Thing t2 = new Thing(2, "Two");

Thing t3 = new Thing(3, "Three");

Thing t4 = new Thing(4, "Four");

currentId = 5;

RootChildren.Add(t1);

RootChildren.Add(t2);

RootChildren.Add(t3);

RootChildren.Add(t4);

radTreeView1.DataSource = RootChildren;

radTreeView1.ChildMember = @"Children\Children\Children\Children";

radTreeView1.ValueMember = "Id";

radTreeView1.DisplayMember = "Name";

}

private void buttonClear_Click(object sender, EventArgs e)

{

radTreeView1.DataSource = null;

}

private void buttonAdd_Click(object sender, EventArgs e)

{

Thing thing = new Thing(currentId, "NewThing" + currentId);

RootChildren.Add(thing);

currentId++;

RootChildren.ResetBindings();

}

public class Thing

{

public int Id { get; set; }

public string Name { get; set; }

public BindingList<Thing> Children = new BindingList<Thing>();

public Thing() { }

public Thing(int id, string name)

{

Id = id;

Name = name;

}
