Please refer the picture from attachment.

Question 1 : How to auto display dot dot dot value when mouse over?
Question 2 : How to auto display full header text when user manually adjust the header size to smaller?

Is possible can be done in telerik?

Hi Stanley,

for question#1, you can set WrapText = true

example:
radGridViewTextBoxColumn1.WrapText = true;

Hi Smith,

Thank you.
But your suggestion cannot work.

Hello,

Thank you for writing.

@Stanley: Regarding your first question, have you set any tooltips at all? Here is the code that enables tooltips and sets the displayed text to the Value of the cell:

private void radGridView1_ToolTipTextNeeded(object sender, Telerik.WinControls.ToolTipTextNeededEventArgs e)
{
    GridDataCellElement dataCell = sender as GridDataCellElement;
    if (dataCell != null)
    {
        e.ToolTipText = dataCell.Value.ToString();
    }
}

There are two options to resolve the second question:

1. As Smith Lo suggested, set the TextWrap property of the column.
2. Subscribe to the ViewCellFormatting event of RadGridView and set the TextWrap property only of the header cells. Here is a sample snippet:

private void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)
{
    if (e.CellElement is GridHeaderCellElement)
    {
        e.CellElement.TextWrap = true;
    }
}

Attached is a screenshot of the result. 

I hope this helps. Write back if you have further queries.
