Hi. I was able to "remove" options and exit buttons which appear at run-time with this code:

 

But how shall i remove this separator line over here which was above options and exit button? 

Hello

I'm using ThemeResolutionService.LoadPackageFile to load a tssp file and apply the theme for the whole application with ThemeResolutionService.ApplicationThemeName = AppliThemeName;

My RadForm (F1) has MdiChildren detect by a RadDock (RD1).

One of these MdiChildren is an other RadForm (F2) which contains a radDock (RD2) which contains some others RadForm (F3x) added with DockControl method.

The F3x RadForms are not themed.

Is there anything else to do for apply theme in this case?

Infos version:

.Net 4.6.1.

Telerik 2017.1.221.40

 Is there any direct feature available to resize the columns in grid by hovering over the left/right border of each Column and clicking/dragging to resize the column width or what is the approach to achieve this.

Hello dear,

I need to know the possibility of enable filtration with some values to show just rows that contain any value from parameters, regards.

I'm using a negative left margin on my tab items.  This causes the tab items to overlap each other a little.  This works during run time, but not at runtime.  At runtime, the tabs start out with the default spacing until I scroll the tabs.  If there aren't enough tabs to cause the scroller to appear, I have to shrink the form to get the scroller, then scroll the tabs and then resize the form again.

Ideally, the tabs would start out overlapping, but I've been looking for a workaround.  Unfortunately, I can't find one.  I've tried refreshing, repainting, invalidating, etc, etc.  The only way I can find to get the tabs to overlap is to scroll them.

Has anyone tried to overlap tabs?  If so, how do you do it?
Has anyone used negative margins before?  If so, have you seen this problem?
Can anyone think of anything to help me.

Thank you.

Got a chart and elsewhere user gets to pick a color.  How can I force a particular series to render in the user specified color?

Thanks -

I have changed the Label on the Trackball to the data I want to display. In this case it is 4 lines. I would like to change the color of each line of text individually. I can change the color of all of the text in the label, but not on a line by line basis. Here is a snippet of my code:

 

I've upgraded multiple machines and installed multiple version of Visual Studio and Telerik Controls to no avail.  The designer is almost completely useless to use. I can't size anything correctly and all controls are very small.  Then when running my application, if I use the GridViewSpreadExport/Renderer, the entire application goes into "TinyFont" mode and nothing is scaled properly.

I've attempted all fixes I can think of, but there is no code that I'm writing that should cause any of this.  I've attached images.  Any help is appreciated.

-- Below is the code that causes issues with scaling after spreadsheet export:

 private void rbExcel_Click(object sender, EventArgs e)
        {
          
            this.progressBar.Visible = true;
            if (File.Exists(BusinessLogic.MyDocFolder + "MyTimeExport.xlsx"))
            {
                File.Delete(BusinessLogic.MyDocFolder + "MyTimeExport.xlsx");
            }

            var spreadExporter = new GridViewSpreadExport(this.rgvWorkEfforts);
            var exportRenderer = new SpreadExportRenderer();
            spreadExporter.HiddenColumnOption = Telerik.WinControls.UI.Export.HiddenOption.ExportAsHidden;
            spreadExporter.AsyncExportProgressChanged += spreadExporter_AsyncExportProgressChanged;
            spreadExporter.AsyncExportCompleted += spreadExporter_AsyncExportCompleted;
            spreadExporter.RunExportAsync(BusinessLogic.MyDocFolder + "MyTimeExport.xlsx", exportRenderer);

        }

Hello,

probably this will be a really simple and stupid question but nevertheless, I am stuck.

 

This is what I tried to do: We store rtf in a database and are planning to use Telerik controls in the future (there is a lot of impressive software inside).

Importing the rtf-text to RichTextEditor is quite easy. I simply put the content of the database field into a string variable and import it into RichtextEditore with this code:

This works perfectly.

After editing the text in RichTextEditor I need to export the new text as rtf to a string to store it in the database. I looked over the documentation and found this:

I tried to assign the function's return value to an another string variable:

VisualStudio puts a wiggled blue line under ExportToRtf() and demanded a missing argument for the functions's parameter "document".

Please tell me where my fault is.

Thanks in advance.

Hi,

// dt is obtains from a database and contains the SQL Look like "Select ID, Parent_ID, Description from Customers"
// Customers is a self-reference table with Parent and Child Relationship

dt is a HUGE recordset contains more than 200,000 records. The Bottle-neck when I executed the code is the DataBinding, it stops on the line RadGridView1.DataSource = dt; Since it is the self-reference table...the RadGridView is display in hierarchy... e.g. Parent has child...child has another child... levels by levels...

public void Page_Load()
{
RadGridView1.BeginUpdate()
RadGridView1.DataSource = dt; 
RadGridView1.Relations.Clear(); 
RadGridView1.Relations.AddSelfReference(RadGridView1.MasterTemplate, "ID", "PARENT_ID"); 
RadGridView1.EndUpdate()
}

My Question is...Can I display the levels by demand ? Yes...there is a demo example on http://www.telerik.com/help/winforms/gridview-hierarchical-grid-load-on-demand-hierarchy.html BUT it is not related to self-reference table...Do you guys has any better approach to do it ?

Many Thanks!
