ExportToExcelML Problem Q2 2010

Hello,

RunExport throws now this Exception: "Cannot find any base cell element!".

My Code:

ExportToExcelML exporter = new ExportToExcelML(gridview);
            exporter.HiddenColumnOption = HiddenOption.DoNotExport;
            exporter.ExportVisualSettings = true;
            exporter.SummariesExportOption = SummariesOption.ExportOnlyBottom;
            exporter.HiddenRowOption = HiddenOption.DoNotExport;
            exporter.SheetName = "Export";

            string filename = Path.Combine(Path.GetTempPath(), "excel_export.xls");

            try
            {
                exporter.RunExport(filename);
                return filename;
            }
            catch (Exception e)
            {
                return string.Empty;
            }

I have no idea what i have to change.

Row's cell value doesn't update when datasource changed.

Ok

I have a simple but annoying problem.

A datatable bound to a radgridview and 1 column is checkboxcolumn. If user clicks the checkboxcolumn, cell goes to edit mode bot not changed the value on the datatable. After press enter button or selecting a different row value changes on datasource.
so I wrote a code for close editor on value changed

private void RouteGrid_ValueChanged(object sender, EventArgs e)

{
RadCheckBoxEditor editor = sender as RadCheckBoxEditor;

if (editor != null)

{

(editor.EditorManager as GridViewEditManager).CloseEditor();

}
}

But my problem is if i want to change the source all values on the grid changes except selected row or current row. I changed all the property of the rows and cells property (IsSelected,IsCurrent...) but value never changes.

Here is my code

private void btnCancelChanges_Click(object sender, EventArgs e)

{

RouteGrid1.CurrentRow = null;

RouteGrid1.Enabled = false;

if (MessageBox.Show("...", "...", MessageBoxButtons.OKCancel, MessageBoxIcon.Question) == DialogResult.OK)

{

DataRow[] Result = null;

this.Cursor = Cursors.WaitCursor;

foreach (DataTable routeTable in viewSalesmanInfo.RouteTableCollection)

{

if (routeTable != null && routeTable.Rows.Count > 0 && !String.IsNullOrEmpty(routeTable.TableName))

{

Result = routeTable.Select("m_Current_State_Id = 0 AND Current_State_Id = -1");

if (Result != null && Result.Length > 0)

foreach (DataRow addCustomer in Result)

routeTable.Rows.Remove(addCustomer);

Result = routeTable.Select(

"(OrderRoute <> m_OrderRoute Or " +

"PaymentRoute <> m_PaymentRoute Or " +

"DeliveryRoute <> m_DeliveryRoute Or " +

"MergeRoute <> m_MergeRoute Or " +

"Route_Position <> m_Route_Position)" +

" OR m_Current_State_Id <> Current_State_Id");

if (Result != null && Result.Length > 0)

foreach (DataRow updateCustomer in Result)

{

updateCustomer.BeginEdit();

updateCustomer["Current_State_Id"] = updateCustomer["m_Current_State_Id"];

updateCustomer["Route_Position"] = updateCustomer["m_Route_Position"];

updateCustomer["MergeRoute"] = updateCustomer["m_MergeRoute"];

updateCustomer["OrderRoute"] = updateCustomer["m_OrderRoute"];

updateCustomer["PaymentRoute"] = updateCustomer["m_PaymentRoute"];

updateCustomer["DeliveryRoute"] = updateCustomer["m_DeliveryRoute"];

updateCustomer.EndEdit();

}

this.Cursor = Cursors.Default;

this.RouteGrid1.MasterTemplate.Refresh();

RouteGrid1.Enabled = true;

}

But after this selected cell value doesnt change.

Is this a bug or is there anything wrong in my code?

convert GridviewSummaryItem aggregate value

I have the following code and I need to convert the value that comes from GridAggregateFunction.sum,

Dim summary As New GridViewSummaryItem("dur", " Total: {0} ", GridAggregateFunction.Sum)

Me.grdResults.MasterTemplate.SummaryRowGroupHeaders.Add(New GridViewSummaryRowItem(New GridViewSummaryItem() {summary}))

The values in the dur column are in seconds and I need to convert that to hh:mm:ss. I have a function that will do the conversion but don't see how to call it on that value (GridAggregateFunction.Sum) before it is displayed in the grid.

I tried several things in the ViewCellFormatting and CellFormatting events but that just causes my app to throw a TargetInvocationException error everytime I start it.

Any ideas would be greatly apprectiated.

[Solved] System dialogs

Hi all,

I am using Telerik RadControls for WinForms 2010Q2 on Win2003 Server, implementing in dotnet 3.5 on Visual Studio 2008. I can't find in RadControls documentation anything about dialog controls for opening files or selecting folders, thus I am using standard OpenFileDialog and OpenFolderDialog. Are there equivalent RadControls? Or is there a way to style standard dialogs like RadControls?

Thanks
Roberto

RadRibbonForm and Mdi help please.

Hi guys,

Are there any examples available that shows how to implement a mdi application where the main form (frame) is a RadRibbonForm and all the child forms have its own RadRibbonMenu? which would be show on the frame when the child is the active document?

For example:
1) A RadRibbonForm acting as the main frame of the application.
2) A child form called Party Form with its own PartyRibbonMenu
3) A child form called Products Form with its own ProductRibbonMenu

If u open a new party form, the form is opened as a new child window in the mdi client window and the main mdi frame window's RibbonMenu is replaced with the party form's PartyRibbonMenu.
Subsequently, if you open a new products form, the RibbonMenu is changed to the ProductRibbonMenu and if you switch between the 2 forms, the menu would change accordingly. (See attached images with child forms and their own menus).

p.s. This was previously done with Telerik Controls for Winforms 2009 Q2 but stopped working when we upgraded to the latest version.
We are in the process of reviewing the current app to see if there's any changes required to make it work with the new version.

Thanks

Jonathan
