Error Handling Help 1

[jtrembla]

I have about 10 grids that use the same error handling code below. Currenly this code is behind all of the grids. Is there a better place to have this code, maybe in a class, and then reference it that way? How would I do this? Kinda new to C#. P.S. I am using winforms if that makes a difference.

private void ultraGridPop_Error(object sender, Infragistics.Win.UltraWinGrid.ErrorEventArgs e)
        {
            // If there is an error while cutting, copying, or pasting, this 
            // event will fire and e.ErrorType will be MultiCellOperation.
            if (e.ErrorType == ErrorType.MultiCellOperation)
            {
                // Cancel the default error message
                e.Cancel = true;
                
                // e.MultiCellOperationErrorInfo returns the error information.
                // Build a custom error message for the user.
                System.Text.StringBuilder SB = new System.Text.StringBuilder();

                SB.AppendFormat("An error has occurred during the {0} operation", e.MultiCellOperationErrorInfo.Operation.ToString());
                SB.Append(Environment.NewLine);
                SB.Append("The error was as follows:");
                SB.Append(Environment.NewLine);
                SB.Append(Environment.NewLine);
                SB.AppendFormat("\"{0}\"", e.ErrorText);

                // Get the cell on which the error occurred
                UltraGridCell errorCell = e.MultiCellOperationErrorInfo.ErrorCell;

                // The ErrorCell will be null if the error was an error in the whole
                // operation as oppossed to an error no a single cell.
                if (errorCell != null)
                {
                    int rowIndex = errorCell.Row.Index;
                    string columnCaption = errorCell.Column.Header.Caption;

                    SB.Append(Environment.NewLine);
                    SB.AppendFormat("The error occurred on Row {0} in Column {1}", rowIndex, columnCaption);
                }

                MessageBox.Show(this, SB.ToString());
                
                
            }
            
        }
        #endregion

public class UltraWinGridErrorHandler

        public static void Error(object sender, ErrorEventArgs e)
        {
            // If there is an error while cutting, copying, or pasting, this

                // Get the cell on which the error occurred
                UltraGridCell errorCell = e.MultiCellOperationErrorInfo.ErrorCell;

                // The ErrorCell will be null if the error was an error in the whole
                // operation as oppossed to an error no a single cell.
                if (errorCell != null)
                {
                    int rowIndex = errorCell.Row.Index;
                    string columnCaption = errorCell.Column.Header.Caption;

                    SB.Append(Environment.NewLine);
                    SB.AppendFormat("The error occurred on Row {0} in Column {1}", rowIndex, columnCaption);
                }

                MessageBox.Show(this, SB.ToString());
                
                
            }
            
        }
}

now for each grid register this static function to grid

MyGrid1.Error += UltraWinGridErrorHandler.Error;
MyGrid2.Error += UltraWinGridErrorHandler.Error;
...

thanks. quick question, where do I register the static function, in the grid error event?

I will give u a star.

 

[jmeckley]

put the class above in it's own file. then when the grid is initialized assign the error event referencing the class's static function.

I am also getting this error.

Error 1 The type or namespace name 'ErrorEventArgs' could not be found (are you missing a using directive or an assembly reference?)

 

[jtrembla]

I put the grid in its class, but too many errors are happening..

Error 1 No overload for method 'Error' takes '0' arguments C:\Documents and Settings\pryan\My Documents\Visual Studio 2005\Projects\Market Forecaster\Market Forecaster\frm_MF_Population.cs 163 40 MarketForecaster

I just had to remove this from the messagebox.show

All set, thanks.

replace [tt]MessageBox.Show(this, SB.ToString());[/tt]
with[tt]MessageBox.Show(sender, SB.ToString());[/tt]
