RadForm on dual screen monitor bleeding into next screen when maximized

I have a Main form that is maximized by default.
I changed the inheritance of my Main form to now inherit from RadForm.
Now when I open the Main form on my left monitor then the Main form has a small edge on the right that is bleeding into the left side of the right monitor.
See attachment for better explanation.

Showing only Date (Not time) in a datetime column in a gridview.

Hi,

How do I format a datetime column in a radgridview control?

I want to show ONLY the date part of the variable.

I DID try removing it before entering it into the Grid, but then it just shows 12:00:00

I am guessing it has to do with DataEditFormatString or FormatString in the advanced settings for the column, but I've tried all kinds of strings with no luck.

Thanks
Johnny

Update property grid from other control.

My question is that is there any way i can get the property grid to reflect my changes that i make from another control. Right now it is working, but the only way i can see the change is when i set focus on the property grid. Is there any way i can force the property grid to update even when it has no focus, so that way as i can make changes to something is can see it been reflected in realtime in the property grid.

[Solved] Override Sort Issue

I am overriding my GetProperties() and Sort Methods of an objects PropertyDescriptorCollection in order to sort by index of a collection.

In the ms winforms propertyGrid this is displaying as expected, while in the Telerik radPropertyGrid it is not performing the same as the picture depicts.

Is there a reason this isn't compatible with the Telerik PropertyGrid?

Below is the code for the PropertyDescriptorCollection sort and GetProperties overrides:

class UserDataPropertyDescriptorCollection : PropertyDescriptorCollection

{

public UserDataPropertyDescriptorCollection(PropertyDescriptor[] propertyDescriptors)

: base(propertyDescriptors)

{

}

public override PropertyDescriptorCollection Sort()

{

PropertyDescriptorCollection ret = new PropertyDescriptorCollection(null);

return this;

}

public override PropertyDescriptorCollection Sort(string[] names)

{

return this;

}

public override PropertyDescriptorCollection Sort(string[] names, System.Collections.IComparer comparer)

{

return this;

}

public override PropertyDescriptorCollection Sort(System.Collections.IComparer comparer)

{

return this;

}

public class UserDataExpandableObjectConverter : ExpandableObjectConverter

{

public override PropertyDescriptorCollection GetProperties(ITypeDescriptorContext context, object value, Attribute[] attributes)

{

PropertyDescriptorCollection d = base.GetProperties(context, value, attributes);

List<PropertyDescriptor> props = new List<PropertyDescriptor>();

foreach (PropertyDescriptor f in d)

{

props.Add(f);

}

UserDataPropertyDescriptorCollection m = new UserDataPropertyDescriptorCollection(props.ToArray());

return m;

}

The object being displayed in the propertyGrid

public class alpha

{

private UserDataCollection usd;

private string test;

public alpha()

{

usd = new UserDataCollection();

test = "Fun";

}

[TypeConverterAttribute(typeof(UserDataExpandableObjectConverter))]

[Category("Collection")]

public UserDataCollection Collection

{

get { return usd; }

set { usd = value; }

}

[Category("String")]

public string Attr

{

get { return test; }

set { test = value; }

}

The form:

public Form1()

{

InitializeComponent();

UserDataCollection temp = new UserDataCollection();

alpha obj = new alpha();

//Inner test = new Inner();

for (int i = 0; i < 25; i++)

{

obj.Collection.Add("");

}

radPropertyGrid1.SelectedObject = obj;

}

The only difference between the two projects is the propertyGrid

CustomItem for property grid.

I am creating a new ItemElementType of CustomItem in the CreateItemElement of the property Grid. I override the CreatePropertyGridValueElement but then i notice that Data pointer is set to null, even though the Item is already create in the createItemElement of the property grid. So my question is that how do i get access to the PropertyGridItemBase object in the CreatePropertyGridValueElement since the only way to create the object it seems like you have to set the e.ItemElementType to a specific type you want to create using reflection.

Thanks.

Customized ContextMenuStrip and Spellchecker ContextMenuStrip at the same time

Hello everybody,

at first, the controls involved in the problem are the following:
- RadTextBox
- RadSpellchecker (spell check as you type mode)
- ContextMenuStrip

I want to use a RadTextBox within a customized ContextMenuStrip and a RadSpellchecker. The problem is, that the RadSpellchecker overwrites the customized ContextMenuStrip with its own ContextMenuStrip if there are wrong words.
Have you an idea how to use the customized ContextMenuStrip and the RadSpellchecker ContextMenuStrip at the same time?

Many thanks in advance for your help
Dennis

Override TextChanged event for RadTextBox

I would like to override the TextChanged event of my own inherited textbox. How should I proceed?
For the Click event of an inherited button I do have the following working code, but for a textbox I cannot find the right way.

using System;
using System.Windows.Forms;
using Telerik.WinControls.UI;

namespace Iap.WinUi.Controls.Button
{
public class QButton : RadButton
{
protected override RadButtonElement CreateButtonElement()
{
return new QButtonElement(this);
}
}

public class QButtonElement : RadButtonElement
{
private readonly RadButton Owner;

public QButtonElement(RadButton owner)
{
Owner = owner;
}

protected override void OnClick(EventArgs e)
{
var form = Owner.FindForm();
try
{
// set wait cursor
form.Cursor = Cursors.WaitCursor;
form.Refresh();

// execute base click code
base.OnClick(e);
}
finally
{
// set arrow cursor
form.Cursor = Cursors.Default;
}
}

protected override Type ThemeEffectiveType
{
get { return typeof (RadButtonElement); }
}
}
}
