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

RadDock loads non-existing controls

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).

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;
                }
            }

Embedding fonts in PDF output

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:
