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.

Hi

I have multiple datapoints in my barseries but when my radchartview is Smaller than specific size columns that have little value is hidden.

in Q1.png when windows is smaller size than Q2.png

what I do?!!

I'm interested in changing the background of the plotting area to a custom background where the top half is one color and the bottom half is another color.  I've attached an image demonstrating the desired effect, though in the image the colors are "on-top" of the points, where I'd like them to be below.  How might I achieve this with Telerik's RadChartView?
