Change Font color on a databoundgrid cell.

[Jonas]

I have a databound grid where I want to mouse over a cell and change it's color, and change it back when you mouse out. (just like an HTTP link)

I used
this.dataBoundGrid1[e.RowIndex, e.ColIndex].TextColor = Color.Red;

For some reason it's not working. I guess I just did not call it right.

Any suggestions?

I coded something like this:

private void dataBoundGrid1_CellMouseHover(object sender, Syncfusion.Windows.Forms.Grid.GridCellMouseEventArgs e)
{
if(e.ColIndex == 1)
{
//MessageBox.Show("Here R: " + e.RowIndex + " C: " + e.ColIndex);
this.dataBoundGrid1[e.RowIndex, e.ColIndex].TextColor = Color.Red;
}
}

Jonas,
In a GridDataBoundGrid, you cannot use indexers to set style properties (other than the Text) for individual cells.To control individual cell style properties in a GridDataBoundGrid, you can handle the PrepareViewStyleInfo event, and set the style properties there based on the e.RowIndex and e.ColIndex. So, if you want to set a color of a cell, you have to do it from PrepareViewStyleInfo (or Model.QueryCellInfo).

Please look at the code snippet below which changes the color of a cell[1,2], and see if it helps you

private void gridControl1_PrepareViewStyleInfo(object sender, Syncfusion.Windows.Forms.Grid.GridPrepareViewStyleInfoEventArgs e)
{
   if(e.RowIndex == 1 && e.ColIndex == 2)
   e.Style.BackColor = Color.Red;			
}

Hey Priti,

I missworded my question. What I wanted to do was to have a set of text in a cell to change its color when you hover your mouse on that cell.

I think you have to use PrepareViewStyleInfo to do something like this. In the event, test whether the mouse is over the cell being requested, and if so, color the text.

To force the PrepareViewStyleInfo event to be fired when you need it, you can use the CellMouseHoverEnter and CellMouseHoverLeave events.

private void gridDataBoundGrid1_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e)
{
	if(e.ColIndex > 0 && e.RowIndex > 0)
	{
		int row, col;
		Point pt = this.gridDataBoundGrid1.PointToClient(Control.MousePosition);
		if(this.gridDataBoundGrid1.PointToRowCol(pt, out row, out col, -1)
			&& row == e.RowIndex && col == e.ColIndex)
		{
			e.Style.TextColor = Color.Blue;
		}
	}
}

private void gridDataBoundGrid1_CellMouseHoverEnter(object sender, GridCellMouseEventArgs e)
{
	this.gridDataBoundGrid1.RefreshRange(GridRangeInfo.Cell(e.RowIndex, e.ColIndex));
}

private void gridDataBoundGrid1_CellMouseHoverLeave(object sender, GridCellMouseEventArgs e)
{
	this.gridDataBoundGrid1.RefreshRange(GridRangeInfo.Cell(e.RowIndex, e.ColIndex));
}
