Image column

Is there a way to create a ListView in which one of the columns is an image column (this is, a column in which to show an image)?. I would like also to be able to turn the visibility of the images on and off. Thank you!

Old GridViewHyperLinkColumn TextAlignment bug resurfaces

I'm currently evaluating Telerik Winforms controls for a project (specifically, the GridView). I downloaded the installer yesterday so I believe I'm using the most recent version (RadControlsForWinFormsSetup_2013_2_724). Everything is working fine except the TextAlignment on GridViewHyperlinkColumns. I found an old forum post about this issue:

http://www.telerik.com/community/forums/winforms/gridview/gridviewhyperlinkcolumn-ignoring-textalignment-bug.aspx

I tried the workaround posted but it didn't work. After some research, I found this page:

http://www.telerik.com/releasehistory.aspx?id=523

Which states the bug was fixed back in the "RadControls for WinForms 2012.3 1017 Oct 17, 2012" release. However, I'm seeing the bug as described in the old forum post. Here's a sample of the data bound to a text box and then bound to a hyper-link column, both with TextAlignment set to MiddleLeft:

Is this a regression issue? Is there a work-around for this? The workaround posted in the original thread no longer works.

Thanks.

“Bounds cannot be changed while locked” on GridView update

I have a List called “myResults”. When the list contains at least one item, I’m trying to populate a GridView w/ info for the list; the GridView is called “gvMyResults”. However, sometimes, during this update of the DataSource, I get an exception saying, “Bounds cannot be changed while locked”, and a red X is displayed across my GridView. I added this Dispatcher wrapper around my update, but I’m still seeing the same error. It’s difficult to troubleshoot, because it does not happen every time. Does anyone know how to stop this “bounds cannot be changed while locked” error?

I have tried to fix this two ways, but both still give the error.

First attempt:

Dispatcher.CurrentDispatcher.Invoke(DispatcherPriority.Normal, (Action)delegate()

{

this.gvMyResults.DataSource = myResults;

});

Second attempt:

_Context.Send(x =>

{

this.gvMyResults.DataSource = myResults;

}, null);

Non-date Value in DateTimePicker

Is it possible for a user to type a non-date value (e.g. [EMPTY]) in the DateTimePicker? I tried everything I could think of, but it always formats the first bracket to a date value.

Column width glitch

Version: 2013.2.612.20
I noticed a strange behavior when trying to change the column width.
Just copy and paste the code below to get the same environment.

Hold the line between columns and move the cursor to the left a little. The first column will reduce its width inappropriately. The cursor remains in the correct position.

The result can be seen in the attached files before.png and after.png.

private void Form1_Load(object sender, EventArgs e)

{
GridViewTextBoxColumn col1 = new

GridViewTextBoxColumn();

col1.HeaderText = "Stretch1";

col1.MinWidth = 100;

col1.Width = 200;

GridViewTextBoxColumn col2 = new GridViewTextBoxColumn();

col2.HeaderText = "Stretch2";

col2.MinWidth = 100;

col2.Width = 200;

GridViewTextBoxColumn col3 = new GridViewTextBoxColumn();

col3.HeaderText = "Static";

col3.MaxWidth = 200;

col3.MinWidth = 200;

col3.Width = 200;

Telerik.WinControls.UI.RadGridView grid = new

RadGridView();

grid.Location = new

Point(0, 0);

grid.Size = new System.Drawing.Size(600, 100);

grid.MasterTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

grid.MasterTemplate.Columns.AddRange(new GridViewDataColumn[] { col1, col2, col3});

Controls.Add(grid);

}

Call another form using the radPanorama

Dear all members and administrators as well,

I've downloaded the trial edition of the new Telerik, I've browsed and tried some new function as well.

Well, the question is simple, I've run the example of the RadPanorama, and when I try to click the Controls Tile such as GridView etc, I couldn't figure out how to do that exactly and properly.

Maybe, the RadPanel could be the solution, however, there are will be some kind of lack of performances, etc.

Can anyone here explain how to show the other form at the same radPanorama. In this study case I want to call other forms. Simple.

Thank you very much for help in advance. GBU

Programmatically alter Header font?

Hey Guys,

I've been trying to alter the font of the column header text. (Bold it if the column is required) based on a flag in the data. This must be done once the data has been loaded, and the requiredness of fields will change.

So 2 questions.....
1) Is there a way to set the Header font (bold/not bold) programmatically?
2) What event should I be using to capture databinding?
   The obvious DataBindingComplete event is not firing when I execute this code: DataGridView1.DataSource = list;
    BindingContextChanged is fired multiple times, but when DataGridView1.DataSource is inspected and is always null...
     So I'm a bit confused about the events...

thanks!!
