I have created a cellrenderer derived from GridTextBoxCellRenderer (to prevent the user from typing certain characters). This works fine. But now I want to remove leading zero characters from the cell if a new value has been entered. E.g. if the user enters "003", I want to change that into "3" when the value has been entered. I tried handling OnDeactivating. In OnDeactivating, I get the TextBoxText ("003"), create a new string based on that ("3"), and then set the TextBoxText to that new string. Somehow, the text in the cell reverts to whatever was in there before I started editing. Is there anything else I need to do to enforce my own value?

Try overriding OnSaveChanges and do your modifications there before setting it into the style for the cell. Below is the current source.
protected override bool OnSaveChanges()
	if (CurrentCell.IsModified)
		GridStyleInfo style = Grid.Model[currentRowIndex, currentColIndex];
		style.FormattedText = this.TextBoxText;
		return true;
	return false;

Wew, that works great ... with some modifications. I took out the "if(CurrentCell.IsModified)" because that never seems to be set. I also had to replace currentRowIndex and currentColIndex by CurrentCell.RowIndex and CurrentCell.ColIndex because currentRowIndex and currentColIndex were "inaccessible due to its protection level". So my code looks like this: protected override bool OnSaveChanges() { // Allow subclasses to react to set the // formatted text TrimLeadingZeroes(); GridStyleInfo style = Grid.Model[CurrentCell.RowIndex, CurrentCell.ColIndex]; style.FormattedText = this.TextBoxText; return true; }
