Hi deva subramanian,

This can be achieved by handling the MouseMove event of RadGridView and by using the ElementTree.GetElementAtPoint method. Consider the code snippet below:

Cursor originalCursor;

void radGridView1_MouseMove(object sender, MouseEventArgs e)
{
    GridDataCellElement cell = this.radGridView1.RootElement.ElementTree.GetElementAtPoint(e.Location) as GridDataCellElement;
    if (cell != null && ((GridViewDataColumn)cell.ColumnInfo).UniqueName == "Value")
    {
        if (originalCursor == null)
        {
            originalCursor = this.radGridView1.Cursor;
            this.radGridView1.Cursor = Cursors.Hand;
        }

    }
    else
    {
        if (originalCursor != null)
        {
            this.radGridView1.Cursor = originalCursor;
            originalCursor = null;
        }
    }
}

I hope this helps.

This doesn't work if its a command column and it has a button with an image. if you move the mouse around the outer edges of the column it will work briefly but if your pointer touches the button image at all it reverts back to the default cursor.

Any recommendations?

Hi,

You can solve this issue by using a slightly modified version of this sample. Here is the code:

void radGridView1_MouseMove(object sender, MouseEventArgs e)
{
    RadElement element = this.radGridView1.RootElement.ElementTree.GetElementAtPoint(e.Location);
    GridDataCellElement cell = element as GridDataCellElement;
    if (cell == null && element != null)
    {
        cell = element.FindAncestor<GridDataCellElement>();
    }
    if (cell != null && cell.ColumnInfo.Name == "xx")
    {
        if (originalCursor == null)
        {
            originalCursor = this.radGridView1.Cursor;
            this.radGridView1.Cursor = Cursors.Hand;
        }

    }
    else
    {
        if (originalCursor != null)
        {
            this.radGridView1.Cursor = originalCursor;
            originalCursor = null;
        }
    }
}

The FindAncestor method is used to locate the cell which owns the button element.

I hope this helps.

HI

 

CellMouseMove not invoked after move from cell to Grid's space area and Cursor would not be restored.

Please test more and more.

 

Best Regards

Hello, Chris,    

The RadGridView.CellMouseMove event is expected to be fired when you move the mouse over the cells. If you don't move the cursor over a cell, the event is not expected to be fired. In this case, the RadGridView.MouseMove event is fired. As to the RadGridView.Cursor, it is set to Default when you hover a cell. If you are between the cells in the thin border that separates the column, the cursor is changed in order to allow resizing the columns. If you need to have the same cursor in the grid, you can handle the CursorChanged event and set the RadGridView.Cursor property to Default if it is changed to some other type.  

private void radGridView1_CursorChanged(object sender, EventArgs e)
{
    if (this.radGridView1.Cursor!=Cursors.Default)
    {
        this.radGridView1.Cursor = Cursors.Default;
    }
}

I hope this information helps. If you have any additional questions, please let me know. 
 

Regards,

Dess
