Tech,

I am using Telerik Version 2009.2.9.701. and Using Telerik.WinControls.Docking.DockingManager in my Form. I am using DockPanel. when user start drag and Drop. I want to prevent user from dropping to Fill DockPosition.

In new version, offers DragDropService which has AllowedDockManagerEdges and PreviewDockPosition to achive this funcnality. But, at this point I can not update the my Telerik Version to new one.so, I have restriction to use only 2009.2.9.701.

Please suggest any solution or workaround that is avilable in 2009.2.9.701 Version in Telerik.WinControl.Docking.dll.

Help would be appriciated.

Thanks.

Drag 'n drop databound

Hi all,

Due to the current lack of support of the RadtreeView for automatic drag and drop when the control is databound, to I am trying to "roll my own". However, I got stuck on a few things, so I really hope someone can help me out.

I have subclassed the RadTreeView, RadTreeViewElement and TreeViewDragDropService classes and am implementing my own versions of OnDragEnter and OnDragDrop. I am assuming that the DragDrop event is the one that I need to override in order to find out on which node the dragged one is dropped.

I can easily find out what node is being dragged by using the value returned in the Data object as below:

drgevent.Data.GetData(typeof(RadTreeNode))

That works fine. However, I am failing to (1) find out what node it is dropped on and (2) what the databound item is for that node. When I use:

var targetNode = this.GetNodeAt(drgevent.X, drgevent.Y)

it always returns null, and I don't see any method or property that returns the item a node is bound to. I was hoping for something similar to the one in the DataGridView (row.DataBoundItem). Is there anything like that, and what do i do to get the node that the dragged item is dropped on?

Thanks in advance (I have been tearing my hair out about this for far too long).

Lucien.

[Solved] Keyboard Delay Too Short

Hi. We're running the 2011.1.11.419 version of this control in our product. Our users have pointed out that the keyboard delat that allows you to jump to longer selections has gotten much smaller. So if you have a dropdown with "Bart", "Bob", and "Olaf", you have to type "bo" very quickly to get to Bob, otherwise your selection ends up on "Olaf". I hope this makes sense... I have no idea what you correctly call this feature.

I tried this on the Winforms RadControls demo app, and I had exactly the same result. The maximum delay you can have between typing the "B" and the "o" seems to be 500ms or less, when I'm sure it used to be 1000ms or more.

For our users this is quite a nuisance, since most of them type with two fingers but need to move quickly through dropdowns with hundreds of options. (On the upside... they're learning to type faster :)

Please let me know if you think this is an issue that has appeared in version 2011 / 419 or not. Thanks.

[Solved] How to use stretch RadComboBox in RadGridView's cell

Hi Telerik's support.
I'm trying to use radComboBox inside radGridView. I made my custom Column and Cell types. As was stated in the article from your site I'm using following code:

txtInput.AutoCompleteMode = AutoCompleteMode.SuggestAppend;

txtInput.RootElement.StretchVertically = true;

txtInput.RootElement.StretchHorizontally = true;

txtInput.TextChanged += TxtInputTextChanged;

Children.Add(txtInput.RootElement);

This code works well in case if instead of ComboBox there will be RadTextBox and TextElement. The problem is RadComboBox has fixed size and doesn't stretch when the size of cell is changed.

[Solved] GridviewCheckBoxColumn check value incorrect when using shorcutkey for button

Hi,

    i have created a sample application to produce the bug. the application contains gridview with one cell which is gridviewcheckcolumn and a rad button to show the messagebox saying whether the check box is checked or not in the gridview.

    when i check the checkbox and if i press the button mesage box showing checked but when i press shortcut key for the button its not working correctly.

    there is a scenarion in my project where we have shortcut key for the button and it behaves like as i said above, so any suggestions on this regard will be helpful for me to solve this issue

private void Form1_Load(object sender, EventArgs e)

{

GridViewDataRowInfo row = this.radGridView1.Rows.AddNew();

}

private void radButton1_Click(object sender, EventArgs e)

{

string name = radGridView1.Rows[0].Cells[0].Value.ToString();

if (radGridView1.Rows[0].Cells["Select"].Value.ToString() == "True")

MessageBox.Show("Checked");

else

MessageBox.Show("UnChecked");

}

Thanks,
Selva

Printing Options with Telerik WinForms

I am interested in printing data with our Telerik Rad Winform Controls. I would like to know what my options are.

Is there an out of the box way to print a GridView?
What are my options for XSLT/XML printing (via HTML)?
What are my options for PDF printing?

If someone can point me to docs on how to print a winforms view, or opinions/ideas from those who have done this - I would really appreciate it!

I wish that as value of property values change in my editor. For example I pass a value to the ID property, I would like with Red or Blue as a possibility and if I go 2 in value to the property ID, I would like to have Green and Black. Is this possible?

PropertyGridSamEditor test = new PropertyGridSamEditor();

test.id = 1;

e.EditorType = test.GetType();

}

In my class PropertyGridSamEditor :

public class PropertyGridSam2Editor : BaseInputEditor

{

public PropertyGridSam2Editor()

{

m_ID = 0;

}

public int m_ID { get; set; }

public PropertyGridSam2Editor(int ID)

{

m_ID = ID;

}

public override object Value

{

get

{

RadDropDownListElement editor = (RadDropDownListElement)this.EditorElement;

List<InfoSam> Isam = new List<InfoSam>();

if (m_ID == 0)

{

Isam.Add(new InfoSam(1, "Rouge"));

Isam.Add(new InfoSam(2, "Bleu"));

}

else

{

Isam.Add(new InfoSam(3, "Bleu"));

Isam.Add(new InfoSam(4, "Noir"));

}

editor.DisplayMember = "Couleur";

editor.SelectedValue = "ID";

editor.DataSource = Isam;

return editor.Text;

}

set

{

RadDropDownListElement editor = (RadDropDownListElement)this.EditorElement;

if (value != null && value != DBNull.Value)

{

editor.Value = value.ToString();

}

else

{

editor.Value = "1";

}

We are using RadGridView in a read-only mode. When our customers select a row, right click and use "Copy", nothing is copied to clipboard. Why is this? What is the best way to allow the user to copy data from the GridView into clipboard?

RibbonBar without start menu and tabs

Hi,

I want to use the ribbonbar without the start menu and tabs. Reason is that I haven't got much buttons/items to put on it, so using tabs and/or start menu will be needless imho. Also I find it's using a bit too much screen space by default.

So, what I want is:

Use the Office 2010 blue/silver theme. The RadRibbonBarGroup title should have a background color, just like in the Office 2007 theme.
No tabs or start menu, so the reserved space for those should/can be collapsed (resulting in more space available on the form).
The height of the RadRibbonBarGroup should be a bit less (enough for an 32 icon, one line button title beneath and the group title).

If someone could provide me a (code) example to achieve this, then that would be much appreciated!
