Error in CurrentCellCloseDropDown

[Administrator]

Hi, I am using GDBG. For one of the column I have ‘ComboBox’ as cell type. I have attached the code related to the ‘CurrentCellCloseDropDown’ event. Problem: When I am at the very last row of the grid (basically new row which doesn’t have any data) and click the dropdown button for that cell but I don’t select anything from the list. I see the list but don’t select any value from list. After clicking on the dropdown button of the cell I click somewhere else which Triggers the ‘CurrentCellCloseDropDown’ event and I get the following error. Type: System.ArgumentOutOfRangeException Message: Specified argument was out of the range of valid values. Parameter name: Index was out of range. Must be non-negative and less than the size of the collection. Stack Trace: at System.Collections.CollectionBase.System.Collections.IList.get_Item(Int32 index) at FOX.FBC.Planning.PL.PlanningClient.DepartmentBudget.SalaryAdjustmentsUserControl.ValidatePayTypeCode(String& validationMessage) in c:\development\application\fox\fbc\planning\1.0\source\pl\planningclient\departmentbudget\salaryadjustmentsusercontrol.cs:line 880 at FOX.FBC.Planning.PL.PlanningClient.DepartmentBudget.SalaryAdjustmentsUserControl.dgEmployees_CurrentCellCloseDropDown(Object sender, PopupClosedEventArgs e) in c:\development\application\fox\fbc\planning\1.0\source\pl\planningclient\departmentbudget\salaryadjustmentsusercontrol.cs:line 851 at Syncfusion.Windows.Forms.Grid.GridControlBase.OnCurrentCellCloseDropDown(PopupClosedEventArgs e) at Syncfusion.Windows.Forms.Grid.GridControlBase.RaiseCurrentCellCloseDropDown(PopupClosedEventArgs e) at Syncfusion.Windows.Forms.Grid.GridDropDownCellImp.DropDownContainerCloseDropDown(Object sender, PopupClosedEventArgs e) at Syncfusion.Windows.Forms.Grid.GridCellRendererBase.DropDownContainerCloseDropDown(Object sender, PopupClosedEventArgs e) at Syncfusion.Windows.Forms.Grid.GridComboBoxCellRenderer.ChildClosing(IPopupChild childUI, PopupCloseType popupCloseType) at Syncfusion.Windows.Forms.PopupControlContainer.OnCloseUp(PopupClosedEventArgs args) at Syncfusion.Windows.Forms.PopupControlContainer.HidePopup(PopupCloseType popupCloseType) at Syncfusion.Windows.Forms.PopupControlContainer.VeryifyMouseBasedDeactivation(Control destinationControl, Int32 msg) at Syncfusion.Windows.Forms.PopupControlContainer.ProcessMouseMessage(Control destination, Int32 msg) at Syncfusion.Windows.Forms.PopupControlContainer.Syncfusion.Windows.Forms.INeedMouseMoveMessages.MouseMessage(Message& m) at Syncfusion.Windows.Forms.PopupManager.PreFilterMessage(Message& m) Source: mscorlib Please suggest what can I do to prevent this error. Probably I am getting this error due the fact the row is new and I didn’t select from list and trying to validate value in ‘CurrentCellCloseDropDown’ event. Thanks,

Hi Vs,

I do not see this error. Just an analyze may help you. If the CurrentCellCloseDropDown be raised as you said in the AddNew row, ValidatePayTypeCode will return true, because cc.Renderer.ControlValue and this.dgEmployees[cc.RowIndex, cc.ColIndex].CellValue are nothing and the are the same, so the statement of execution leaves this block.

if(cc.Renderer.ControlValue != this.dgEmployees[cc.RowIndex, cc.ColIndex].CellValue)
{

}

Best regards,
Stanley

If I commented out the following lines of code from the event then everything is working fine, so it is proven that error is caused by the ValidatePayTypeCode method call.

string validationMessage;
if (!this.ValidatePayTypeCode(out validationMessage))
{
this.dgEmployees.CurrentCell.CancelEdit();
this.dgEmployees.Binder.CancelEdit();
MessageBox.Show(validationMessage);
}

Please help.
Thanks,
