here is this moment:

How do I not delete items but just hide or display them?
It is necessary to do it in this moment.
Thank you.

Good afternoon.

I want to change the color according to the Data value of a certain column in Cardview.
Cardview does not have a CellFormatting in the Gridview or Listview.

I change the color of the entire item using Cardview's VisualItemFormatting.

        private void RadCardView1_VisualItemFormatting(object sender, ListViewVisualItemEventArgs e)
        {
            if (e.VisualItem.Data["EIFSTATUS"].Equals("OFF"))
            {
                e.VisualItem.BackColor = Color.Red;
                e.VisualItem.GradientStyle = Telerik.WinControls.GradientStyles.Solid;
            }
        }

But I do not want it.

I would like to change Backcolor only for "OFF" value only when the column value of "EIFSTATUS" is "OFF" instead of whole.

I want to change it like the Grid screen below.

private void RadGridView1_CellFormatting(object sender, CellFormattingEventArgs e)
        {
            if (e.CellElement.ColumnInfo.HeaderText == "EIFSTATUS")
            {
                if (e.CellElement.RowInfo.Cells["EIFSTATUS"].Value.Equals("OFF"))
                {
                    e.CellElement.DrawFill = true;
                    e.CellElement.GradientStyle = GradientStyles.Solid;
                    e.CellElement.BackColor = Color.Red;
                }
            }
        }

I would appreciate your help.

I have a very simple RadLayoutControl with two LayoutControlItems inside it - each Control Item has a RadListControl - these are stacked on top of each other.

Each LayoutControlItem is the same height - a 50/50 split which is exactly what I want.

Unfortunately because of how WinForms are displayed - the form is first drawn as the same size as it is in the designer...then everything expands to the actual size of the form and you get this ugly double-painting effect...my RadLayoutControl is shown...then blink and it's redrawn at its Run-Time size and everything resizes correctly.

Well, I hate that WinForms do that...and I'm not smart enough to know how to tell the application, "Hey! Don't draw anything until the form has finished resizing!" so I fake it...anything that gives me this double-paint I set Visible = false and once the form's finished its resizing I set Visible = True.

My problem is this:  With the RadLayoutControl doing this:  The TOP panel is the same size as in the designer and only the bottom panel resizes to fill the rest of the space.

My question is this:  Is there any way I can tell the RadLayoutControl, "Take your current height and go resize everything equally" so I wind up with two panels the same height?

I've attached a couple of images to show you what I mean.  One shows you how I want it to look and the other shows how it does look.  Hopefully you can make sense of this post and I don't sound like some crazy guy trying to do something I shouldn't be...heck if anyone there knows anyway to tell a WinForm not to paint until it's resized that would solve everything :)

The following link has a great example for Button FillPrimitive.

https://docs.telerik.com/devtools/winforms/telerik-presentation-framework/override-theme-settings-at-run-time

However, I am having a lot of trouble trying to do the same thing with my RadButton's BorderPrimitive.

The following does not work.

this.radButton1.ButtonElement.SetThemeValueOverride(Telerik.WinControls.Primitives.BorderPrimitive.ForeColorProperty,Color.Red, "", (Telerik.WinControls.Primitives.BorderPrimitive));

What will work? I tried accessing this.radButton1.ButtonElement.BorderElement but there is no SetThemeValueOverride member.

Hi, 

I am very confused with validating data before sending it to the DB. 

My Grid is popultated with datatable (from Web service) and I would like to send row data each time the user finishes to edit the row (send via Web Service) and also I would like to send a new row data by using a web service call with the params as needed. 

The proble is that I do not know wich event to use sa there are a lot. 

I tried to use grid_RowsChanged but I do not know if I should also use RowValidating as rows_Changed occured before row_valdating. or should I use only rows_changed? there is also a user_added_row event... please help.. 

I want to let user finish add new row then check if everything is valid. If it is not valid I would like to prevent him from pushing data (rovalidating is the only way I have to cancel telerik grid action to add the new row or accept the current row changes. 

It is very consfusing, could you please help me.

How can I disable the Complete Message Box from the SpellCheck in the RadRichTextEditor?

In RadSpellChecker I can use the property EnableCompleteMessageBox, but in RadRichTextEditor I can't find it.

Regards.
