Hi,
I urgently need a help ..and hight appriciate if experts on this forum can respond with a code snippet

I am editing a datagrid Cell with below code ( on cellEditEvent) , Function works perfectly fine when i changed the value for cell first time...but if tried to change any other cell value ( after successfully trying once) ... it goes to the same celleDit function and throw following exception

System.FormatException was unhandled by user code
Message="Input string was not in a correct format."
StackTrace:
       at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal)
       at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info)
       at System.Int32.Parse(String s)
       at HandlingUnit.SourcePackaging.RadGridViewValidation_EditEnded(Object sender, GridViewCellEditEndedEventArgs e)
InnerException:

My code

private void RadGridViewValidation_EditEnded(object sender, GridViewCellEditEndedEventArgs e)

{

int OldCellValue = int.Parse(e.OldData.ToString());

int NewCellValue = int.Parse(e.Cell.Content.ToString());

if ((OldCellValue > 1) &&(e.Cell.ParentRow.Cells[3].Content.ToString()==""))

{

objTargetAllocHUdata.TargetHUItemNo = e.Cell.ParentRow.Cells[1].Content.ToString();

objTargetAllocHUdata.TargetHUQuantity = TargetHuQuantity.ToString();

objTargetAllocHUdata.TargetHUSerialNo = e.Cell.ParentRow.Cells[3].Content.ToString();

//objTargetAllocHUdata.TargetSerializableOrNot = row.Cells[4].Content.ToString();

objTargetAllocHUdata.TargetHandlingUnitNo = (HUAutoGeneratedNo + 1).ToString();

//Adding to Target list

lstTargetAllocHUData.Add(objTargetAllocHUdata);

this.TargetRadGridView.Rebind();

this.TargetRadGridView.ItemsSource = lstTargetAllocHUData;

}

public SourcePackaging()

{ InitializeComponent();

lstTargetAllocHUData= GetMessages().ToList();

this.SourceRadGridView.ItemsSource = GetMessages();

this.SourceRadGridView.CellEditEnded += this.RadGridViewValidation_EditEnded;

this.SourceRadGridView.ValidationMode = ValidationMode.Cell;

}

Further researching in to this suggest that

When first time function is called below code executes successfully ,....but if a second cell is edited e.OldData and e.NewData returns null or blank values ..and hence it is failing ,,,please suggest what should i do so that they don't take null/ blank values in second call of the function

private

void RadGridViewValidation_EditEnded(object sender, GridViewCellEditEndedEventArgs e)

{

int OldCellValue = int.Parse(e.OldData.ToString());

int OldCellValue = int.Parse(e.OldData.ToString());

}
