I'm not sure exactly which forum/discussion to ask this in. If I'm in the wrong place, I'm sorry.

I've built a WinForms app that I want to display some reports using the ReportViewer. What I want to do is set the palette for these reports using a custom palette class I've added to the WinForms project.

I have the reports in their own project so that if users decide they want a web app I can easily reuse the reports (hopefully).

I don't know how to set the palette on the report and i can't find anything online about how to do this. I know I can go into each report and set the colors individually but that is not efficient or scalable.

My code in the Winforms app to set the report in the ReportViewer is like this...

I figured out how to use the custom palette with charts within the winforms app like this...

I want to be able to do something similar in the Winforms app. I don't want to have to copy my CustomPalette class over to my ReportsLibrary project.

Is this possible?

I want to be able to do something like...

Hi Telerik,

I noticed that, there is no "VirtualGridCheckBoxEditor" class. Not sure why. So I decided to create a check box editor by following Telerik's documented approach. See the code below which is my checkbox editor. However, the checkbox, when the cell is in edit stage, is not rendered at the center of the cell element (see attachment checkboxeditornotcenter.png).

Please assist.

Thank you,

Saj.

            return elmnt;

        {
            base.Initialize(owner, value);

Hello,

i am using the grid view in virtual mode. The columns are populated with data in the CellValueNeeded Event. This works very well.

Now i was trying to add an additional column to the grid that shall be polpulated by the user with data generated by the build in Expression Editor.

The Expression Editor is shown for the column, but i am not sure what to write into the CellValueNeeded Event for this column with the Expression Editor(or if this is even possible)

Thank You for Your help.

Hello, We are licensed customer of Telerik. I am using telerik winforms library version 2016.3.1024.20. I am faced with a problem, as described below.

In the Virtualgrid's EditorRequired event, for a particular cell, I changed the default editor to a new editor like below.

        private void Grid_EditorRequired(object sender, VirtualGridEditorRequiredEventArgs e)
        {
            switch (e.ColumnIndex)
            {
                case 0:
                    {

                        VirtualGridTextBoxControlEditor editor = new VirtualGridTextBoxControlEditor();
                        editor.CharacterCasing = CharacterCasing.Upper;
                        e.Editor = editor;
                    }
                    break;
          }

     }

What happens now is, when I click on the cell, the cell becomes editable, and I can type in it, but I cannot backspace on the cell to delete the characters entered. In addition to that I don't even get the CellValidating event. Besides, the KeyUp event on editor's element (RadTextBoxControlElement) is also not fired.

Could you please help me out? This is urgent because I am running into a pre-Christmas release.

Thank you,

I really like the waiting bar indicator on Virtual Grid as seen here http://docs.telerik.com/devtools/winforms/virtualgrid/busy-indicators

But, I can't seem to find this funtionality on a regular RadGridView. Is that possible?

Hello.

I need to extend RadTextBoxControl element by inheritance. Basically I need to add IsRequired property (this is simple).

Next I need to be able to see the control in Visual Style Builder and define how it will look when this IsRequired property is set to true.

I could not get this information from documentation.

Thank you!

Hello,

i use a DateTimePicker for my application to select a day. The selection is inside a very narrow time Intervall (1 - 3 Days). So i set the MinDate and MaxDate of the DateTimePicker accourdingly. When the Intervall is lager than 1 day the DateTimePicker works correctly. When the MinDate and the MaxDate is equal (only one day available, date cannot be changed) the display of the DateTimePicker is not correct:

Only the days before the actual date are grayed out.

It is possible to switch to different month / years (after teh actual date) with the build in functions.

Nevertheless is it not possible to select another day (which is good), but the user might get confused that his selection does not change the date.

Please confirm this behaviour and please provide a workaround for this behaviour.

Thank You.
