ToolTip Width

[solution]

I use the following code to display a tooltip. My problem is that I cannot set the tooltip maximum width. How can I do this?

GridDataCellElement cell = sender as GridDataCellElement;
if (cell != null && cell.ColumnInfo.Name == "MessageText")
{
    e.ToolTip.OwnerDraw = true;
    e.ToolTip.Draw += ToolTip_Draw;
    e.ToolTip.AutoPopDelay = int.MaxValue; // 24.86 days

    e.ToolTipText = cell.Value.ToString();
}

void ToolTip_Draw(object sender, DrawToolTipEventArgs e)
{
    e.Graphics.FillRectangle(SystemBrushes.Info, e.Bounds);
    e.DrawBorder();
    e.DrawText(TextFormatFlags.RightToLeft | TextFormatFlags.Right);
}

GridDataCellElement cell = sender as GridDataCellElement;

if (cell != null && cell.ColumnInfo.Name == "MessageText")

{

    e.ToolTip.OwnerDraw = true;

    e.ToolTip.Draw += ToolTip_Draw;

    e.ToolTip.AutoPopDelay = int.MaxValue; // 24.86 days

                

    e.ToolTipText = cell.Value.ToString();

}

void ToolTip_Draw(object sender, DrawToolTipEventArgs e)

{

    e.Graphics.FillRectangle(SystemBrushes.Info, e.Bounds);

    e.DrawBorder();

    e.DrawText(TextFormatFlags.RightToLeft | TextFormatFlags.Right);

}

Hello,

Thank you for writing. 

Note that RadGridView uses the MS Tooltip. In order to change its size, you can refer to the following link the ToolTip.Popup event, the ToolTipSize is modified according to exact requirements: http://www.c-sharpcorner.com/uploadfile/hrojasara/how-to-change-the-size-of-tooltip/

I hope this information helps. Should you have further questions I would be glad to help.
