I have a user control that contains a radlabel and a radmaskedtextbox. I need to change the backcolor of the textbox to match the forecolor of the radlabel when the user control is disabled. Everything works fine if the user control is initially enabled. However, If I set the initial state of the user control disabled, then upon running the program, the maskedtextbox's backcolor is black while the forecolor of the radlabel is gray. Here is the code: 

Im use this function for editing the style (ex color, font) of radelement

RadElementHierarchyEditor

http://www.telerik.com/products/winforms/element-hierarchy-editor.aspx

Now i need to change the color of form element but radform does not have RadElementHierarchyEditor

How to change the color Green to Red for example?

I found several solutions in our forum, but all change the "theme", not only the color.

I develop many applications in C #. Net for Windows Forms and am considering the purchase of various frameworks, according to the most changeable.

     Dim Trackball As New ChartTrackballController()
     AddHandler Trackball.TextNeeded, AddressOf trackball_textNeeded
     Trackball.InfoElementOffset = New System.Drawing.Point(0, -20)
     rChartView.Controllers.Add(Trackball)

    The Web-Version of RadGridView, has the EditForm Mode, to edit the Content of a row, with some customized Control.

In the WinForms Version of RadGridView I'm missing this Mode.

There are GridViewTemplates and Grouping and Hierarchy Staff, that 'expand' a Row,

that link to different tables or different rows.

I haven't found any example, to expand just an Edit Control of the Row, with a more appealing presentation, when inside cells, for example.

How do I edit the row itself in the expanded part - without having a Hierarchie of anything.

The overwie page, has something almost like that:

http://docs.telerik.com/devtools/winforms/gridview/overview
But this is Non-Edit (I assume)

and it does not come with the source Code.

Also the Webinar does not handle GridViewTemplates.

Hello,

  I have created a GridViewTextBoxColumn(), on _CellPaint() I am painting three images starting from the left to right.  I would like to detect a mouse click on the rectangle that corresponds to the image but I can't get the Cell.Size information on the CellClick() event.

I have tried creating a custom control that holds three buttons but the UI doesn't fit my needs.

In order to determine what was clicked on the cell, I need to know the click x/y and the current cell rectangle.

Thanks!

void grid_CellPaint(object sender, GridViewCellPaintEventArgs e)
        {
            GridDataCellElement dataCell = e.Cell as GridDataCellElement;
            if (dataCell != null && dataCell.ColumnInfo.FieldName == "ID")
            {
                Size cellSize = e.Cell.Size;
                Rectangle rct = new Rectangle(0, 0, cellSize.Height, cellSize.Height);
                //using (Pen p = new Pen(Color.Black))
               // {
                 
  //Flag
                    rct.Inflate(-2, -2);
                    e.Graphics.DrawImage(global::DIRC.UITools.Properties.Resources.Flag_red_icon16x16, rct);
           

                    //Information Icon
                    rct = new Rectangle(cellSize.Height, 0, cellSize.Height, cellSize.Height);
            
                    rct.Inflate(-2, -2);
                    e.Graphics.DrawImage(global::DIRC.UITools.Properties.Resources.information_icon_16x16, rct);

                    //Comment Icon
                    rct = new Rectangle(cellSize.Height * 2, 0, cellSize.Height, cellSize.Height);
                     
                    rct.Inflate(-2, -2);
                    e.Graphics.DrawImage(global::DIRC.UITools.Properties.Resources.comment_icon16x16, rct);
               // }
            }
        }

I'm creating a GridViewColorColumn and I would like to modify it's look. I just want the color box showing the color and the button, no text. It would be nice if I could make the color box wider also.

 VB code please.

   Private Sub grdMainGrid_DataBindingComplete(sender As Object, e As GridViewBindingCompleteEventArgs) Handles grdMainGrid.DataBindingComplete

        Dim colorBoxColumn As New Telerik.WinControls.UI.GridViewColorColumn
        colorBoxColumn.DataType = GetType(Color)
        colorBoxColumn.HeaderText = "Staff Color"
        grdMainGrid.Columns(2) = colorBoxColumn
        grdMainGrid.AllowEditRow = True
        grdMainGrid.Columns(2).ReadOnly = False

​end sub

I'm using 2016 Q1 Jan and the VisualStudio2012Light theme. I'm using a RadDropDownList with AutoCompleteMode = SuggestAppend.

I have a problem where if the values for the items in the list are very long then when you start typing and the suggestions appear then they overlap and make it very difficult to read.

When viewing the items in the list normally there is no problem and the items have ellipses.

Can you please assist?

I need to change the background color of many Rad controls when they are disabled, RadDropDownList is one of them. I have searched up the forum but have not found a satisfactory answer. I am wondering if there is a built-in property that I can just set, so that each time RadDropDownList is disabled, its background color changes to black or gray, instead of the default disable-color. 

I understand that there is a built-in property to set default disable paint to false, it is shown in the code below. But then, how can I set up a custom disable paint? 

From filtering box, when I select Null and then select All then the following error occurs:

Item has already been added. Key in dictionary: '(Blanks)'  Key being added: '(Blanks)'

Please see the attached screenshot.

Hello,

I've had issues using Telerik for WinForms for a couple of weeks.

I thought I had cured it all last week when I updated my Telerik Control Panel and then updated the suite of controls.

The WinForms app I am working on will not allow me to add any Telerik controls to any Telerik form.

I tried repairing the Telerik WinForms components which didn't work.

I then uninstalled the Telerik WinForms components and re-installed them. Everything appears to install fine but my project will still not allow me to add controls (I can add RadForms though).

Every time I try to add ANY control I get a messagebox saying: "Failed to created component Rad.... The error message follows"....

Why is trying to re-add a reference to Telerik.WinControls.UI every time a new control is placed onto a form?

I am running Windows7 64-Bit - The references in my app are:

Telerik.WinControls

Telerik.WinControls.UI

TelerikCommon

Paths to files are:

C:\Program Files (x86)\Telerik\UI for WinForms Q1 2016\Bin40\Telerik.WinControls.dll

C:\Program Files (x86)\Telerik\UI for WinForms Q1 2016\Bin40\Telerik.WinControls.UI.dll

C:\Program Files (x86)\Telerik\UI for WinForms Q1 2016\Bin40\TelerikCommon.dll

Which are the latest downloads via Telerik Control Panel this afternoon.

Has anyone else experienced this issue? It's holding me up a lot.

Thanks.
