Hi Rafal Dabrowa,

You can not change the anti-aliasing of the text in grid, because you can not do it for the basic visual element of TPF. We have addressed this feature request in the next major release Q1 2010. In the meantime, you may change the text anti-aliasing mode of the current operation system. This will affect the text rendering mode in the Telerik Controls.

Regarding the multiline text in the header, you can set WrapText property of the header cells to true. After that, you should specify the width of the columns. Then your text will be arranged on one or more lines depending on its length. Here is the sample how you should do it:

this.radGridView1.DataSource = dtSource;

GridTableHeaderRowElement tableHeaderRow = this.radGridView1.GridElement.FindDescendant<GridTableHeaderRowElement>();

foreach (GridCellElement cellElement in tableHeaderRow.Children)
{
    if (cellElement is GridHeaderCellElement)
    {
        cellElement.TextWrap = true;
    }
}
this.radGridView1.Columns["ID"].HeaderText = "The is a long long text";
this.radGridView1.Columns["ID"].Width = 100;

If you have further questions, feel free to ask.

Hi Rafal Dabrowa,

I apologize for my previous answer. It was based on the current development version which will be shipped in the next major release. You should set WrapText property of the column to true and AutoSizeRows property of the grid to true.

this.radGridView.AutoSizeRows = true;
this.radGridView.Columns[1].WrapText = true;
this.radGridView.Columns[1].HeaderText = "This is a long long text";

Let me know if you need further assistance.

If i just want to add the multiline to the header text only  but not the columns data itself.
I hope to configure these settings at design time.
or the only way to do it is via writing code ?
I am using Q1/2010 SP1.

thanks

Hello Imran Khalid,

Presently, you cannot do that design time. You can wrap the text of header cells by setting their TextWrap property to true. Also you have to enable clipping by setting ClipDrawing property to true. You need to do that in ViewCellFormatting event. You can use the following code snippet:

this.radGridView.ViewCellFormatting += new CellFormattingEventHandler(radGridView_ViewCellFormatting);
this.radGridView.AutoSizeRows = true;

private void radGridView_ViewCellFormatting(object sender, CellFormattingEventArgs e)
{
    if (e.CellElement is GridHeaderCellElement)
    {
        e.CellElement.TextWrap = true;
        e.CellElement.ClipDrawing = true;
    }
}
