Validation of the current cell

[Administrator]

Hi,
I am using the current cell validated eventhandler for DataBoundGrid.

My requirement is when the user enters the text in the cell,it should be validated and if the entered value is invalid and it should revert back to the original text.

For this is this the correct event handler to use?

How do we reset the text?
i used m_ListingGrid.CurrentCell.Renderer.ResetControlText();

You should be using CurrentCellValidating which gives you the option of cancelling moving to another cell by setting e.Cancel = true. To access the ''new'' value in this event so you can test it as to whether it is valid, use grid.CurrentCell.Renderer.ControlText.

Hi,
I want to check if the text entered in the cell is correct when the cell loses focus and if text is not correct i want to revert back to the original contents

There is no event called CurrentCellLostFocus...
I used CurrentCellControlLostFocus but there i am not able to get the original and changed value.

Which event will be appropriate to use.
I dont want to restrict the movement or editing of the cell.

Use CurrentCellValidating, but do not set e.Cancel = true.

GridCurrentCell cc = this.grid.CurrentCell;
GridCellRendererBase cr = cc.Renderer;
string newValue = cr.ControlText;
string oldValue = grid[cc.RowIndex, cc.ColIndex].Text;
if( NewValueIsWrong )
{
	cr.Control.Text = oldvalue;
}
