I'm trying to programmatically add a tab to the Ribbonbar at runtime. It all works fine when the Ribbonbar is expanded. But when I add a tab to a collapsed Ribbonbar the new tab is not visible until I click the button to expand the Ribbonbar again. Here are the steps to reproduce:

1.Create a new Visual C# -> Telerik Windows Forms Application

2.Drag a RadRibbonBar control onto RadForm1

3.Create a single tab "First Tab" (otherwise you cannot collapse the ribbon)

4.Drag a button onto the form and add the following code to the click event handler:

5.You should end up with something like the attached png file.

6.Run the project and click the button. You should see the new tab is created and selected.

7.Close the project and run it again. This time collapse the ribbon before clicking the button. No new tab is visible on the ribbon. Even if you click on the [First Tab] to show the full ribbon.

8.Click the expand ribbon button on the right and the new tab will then appear.

I've tried adding lines like Application.DoEvents() or this.Refresh() or this.radRibbonBar1.Refresh() but it doesn't make a difference.

Any help would be much appreciated.

Thanks,

John

Hello,

I open the window containing RadGridView as follows:

new System.Threading.Thread(delegate () {

When trying to copy data from the grid (right click -> copy) error message pops up:

In this case I can't avoid new thread when calling new form.

How to solve it?​

Hi, I am currently using the trial version of Telerik Winform and I would like a code example on how to aggregate cells in my gridview with the following two examples.

 Example1:

1997     a                                           a

1997     b  ->  becomes  ->   1997     b

1997     c                                            c

 Where 1997 becomes a vertical aggregate field.

Example2:

1997     1997     1997 ->               1997

a            b           c               a          b          c

Where 1997 becomes a horizontal aggregate field

We have a problem using the radDock.LoadFromXml() and radDock.SaveToXml() functionality. This is the case:

 1. We created an application some time ago, version 1.0. This application uses radDock.LoadFromXml() and radDock.SaveToXml() to save and restore the window settings.

2. We added new windows to this application in version 2.0.

3. People do use the original application (next to the new one) though, resulting in showing windows that do not exist in version 1.0 (!)

Is there a way to repair this? I know I can save and load the settings in a different file, but I am looking for a better solution (since we will have more new versions of our application).

using this code  part to exclude summaryRows from Search loop. 

#code

public class SearchRow : GridViewSearchRowInfo
{
    public SearchRow(GridViewInfo viewInfo) : base(viewInfo)
    {
    }
 
    protected override bool MatchesSearchCriteria(string searchCriteria, GridViewRowInfo row, GridViewColumn col)
    {
        if (row is GridViewSummaryRowInfo)
        {
            return false;
        }
        return base.MatchesSearchCriteria(searchCriteria, row, col);
    }
}
 
private void radGridView1_CreateRowInfo(object sender, GridViewCreateRowInfoEventArgs e)
{
    if (e.RowInfo is GridViewSearchRowInfo)
    {
        e.RowInfo = new SearchRow(e.ViewInfo);
    }
}

#code

And now i cant itterate through search results, i can only choose the first one and the last one​.

I have problem when using currentrowchanging event,

 when first load the grid, when I change the row,, the event fire correctly, this is my event,

buf after sorting or grouping it appear not correct.....

this is the condition

1.  when I click the row in index 4  (ID = ROM and name = ROMA VATIKAN), buf after sorting the column country name, when I click the index   4  (ID = ​ALS and name = ALASKA),  the value is still (ID = ROM and name = ROMA VATIKAN) not  (ID = ​ALS and name = ALASKA)... how to get value ID = "ALS" in index for,, look for the attachment image (grid after order by.png)

2. when I click the row in index 1  (ID = ​BGR and name = ​BOGOR), buf after grouping the column country name, when I click the value  (ID = ​​ROM and name = ​ROMA VATIKAN),  the value is still (ID = ​BGR and name = ​BOGOR) not  (ID = ROM and name = ROM VATIKAN) cause it refer into index = 1... how to get value ID = "ROM" in index for,, look for the attachment image (grid after grouping.png)

this is my currenrowchanging event

  void gridData_CurrentRowChanging(object sender, CurrentRowChangingEventArgs e)
        {
            if (gridData.RowCount != 0)
            {
                int rowindex = 0;

                if (e.NewRow == null)
                {
                    ClearData();
                    return;
                }

                rowindex = e.NewRow.Index;
                //}

                txtID.Text = gridData.Rows[rowindex].Cells["ID"].Value.ToString();
                txtName.Text = gridData.Rows[rowindex].Cells["Name"].Value.ToString();
                cmbCountryID.Text = gridData.Rows[rowindex].Cells["CountryID"].Value.ToString();
                cmbCountryName.Text = gridData.Rows[rowindex].Cells["CountryName"].Value.ToString();

                if (gridData.Rows[rowindex].Cells["ActiveStatus"].Value.ToString() == "1")
                {
                    rbYes.IsChecked = true;
                }
                else
                {
                    rbNo.IsChecked = true;
                }
            }
        }

Hello everyone,

We are using the RadRichTextEditor as a document creation tool for our users. Once the document is created, we export it to PDF using the standard pdf export provider. The issue here is that fonts used in the RadDocument do not get embedded into the PDF file.

I've already contacted support about this and a feedback item has been created, but we are really left dead in the water without the ability to embed fonts (since our clients often view the pdf on mobile devices). Has anyone found a workaround to this?

More detail here:
