I have a GridView with a  GridViewDateTimeColumn, and I have managed to figure out how to display no text in the editor when the cell value is null, however I need to also allow the user the  option of setting the value to null if a value exists.

When the pop up editor appears, i cannot see a way to customize the popup or the text editor to allow this to happen.

        private void gvLibrary_CellEditorInitialized(object sender, GridViewCellEventArgs e)
        {
            GridTimePickerEditor editor = e.ActiveEditor as GridTimePickerEditor;
            if (editor != null)
            {
                RadTimePickerElement editorElement = editor.EditorElement as RadTimePickerElement;
                editorElement.Format = "HH:mm:ss";
                editorElement.NullText = "";
                editorElement.NullValue = 0;
                if (e.Value != null)
                {
                    editorElement.Value = e.Value; 
                }
                else
                {
                    ((TextBox)(editorElement.MaskedEditBox.TextBoxItem.TextBoxControl)).Text = "";
                }
            }
        }

Can you provide me with the necessary elements to allow the user to delete values in the text box or from the pop-up and a way to ensure that the editor's null value is passed to the grid cell?

Thank you,

Vania

Hi i navigate RadGrid view using following code

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!

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.

Hello, everybody.
Sounds strange, but i can't find event of maximisation button of radform.
I need to resize form content and i can't do it in maximisation mode. I created special method for resizing and it works when i resize form slowly by getting corner, but resizing events don't work after maximizing((
Who knows how to solve this issue?

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.

Hi,

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.

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.
