Hello,

I have a gridview which display workitemdata. The columns are "The client", "The service contract", "The Employee", "The Date", "Hours", "Description", "price hour" and "Value (price hour * hours). The client, service contract and employee are ID value not string.

I have made a three level grouping on Client, service contract and Employee.

I have added a summary row for displaying the total of Value by group and an Handler on GroupSummaryEvaluate for displaying an human readable string instead of ID.

But I'm stuck on these problems:

I want only to display the subtotal (the summaryRow) on the client group level (last level). The showParentGroupSummaries properties work for each level (true) or the first level (false).
The GroupSummaryEvaluate handler change the display string of my group header AND my summaryRow.
What are the options for formatting my summaryRow (like text alignment, font, ...)
The group sort my values on ID (column value) before grouping. Is there a way to sort on the readable string after the grouping. I could use a numeric enumeration based on my string instead of an ID for grouping. Just asking if there is a kick tip about this :-)

I join two picture (GroupSummaryEvaluate active/not active) and some code.

[Sitefinity 5.0.25] radcombobox not working in IExplorer10

Hello
In my website I have lots of pages using Comboox component
Users browsing with IExplorer 10 have revealed that the combo were empty, even if they are correctly bound to sql database
I do not have IE10; with Chrome, Firefox and former versions of IExplorer all is OK.
How can i fix this 'bug'? Is it just a problem of Sitefinity updates?
Is it possible to force a WebApplication to open in IE10 in compatibility mode?
Thanks in advance

Disable changing cursor in Gridview cell

Hello,

in my DataGridView I have a column for E-Mail adresses. The user clicks on the E-Mail adress and my programm opens a new E-Mail.
When the mouse is over the E-Mail adress I have this CellMouseMove Event to change the Cursor (to Cursor.Hand):

private void dg_CustomerContact_CellMouseMove(object sender, MouseEventArgs e)

{

GridDataCellElement cell = this.dg_CustomerContact.RootElement.ElementTree.GetElementAtPoint(e.Location) as GridDataCellElement;

if (cell != null && ((GridViewDataColumn)cell.ColumnInfo).Name == "dg_TalkedWith_col_Email")

{

originalCursor = this.dg_CustomerContact.Cursor;

this.dg_CustomerContact.Cursor = Cursors.Hand;

}

else

{

if (originalCursor != null)

{

this.dg_CustomerContact.Cursor = originalCursor;

originalCursor = Cursors.Default;

}

But when there is no E-Mail adress the cursor should not change to "Cursor.Hand". Any suggestion how to solve this?

Custom trackbar editor keeps the value displayed underneath

Using the custom editor code sample for Telerik winforms found on the Telerik website, I override the BaseInputEditor
to provide my propertyGrid with a trackbar editor.

Now, I implemented the onEditorRequired method as explained to replace the basic edition mode for
any int property.

I'm using the RadPropertyStore mechanism to fill my property grid.

I've no problem with having the value displayed as a number when the editor is not activated, but I'm
not willing to have the value being displayed underneath the track bar as I'm editing the value.

Anyway, I would be looking for having the track bar always displayed even if the property is not being
edited as it will be used for an opacity setting.

Thanks in advance,
Antoine

How to toggle resources to view

Hello,

I only want one given resource to be viewed at any point on the scheduler. I have multiple resources, but I cannot seem to find out how to toggle which resource should be viewed. It just shows the first resource I added to the collection, and then at runtime I can't see a way to toggle between those resources:

Also, I forgot to dereference a radscheduler from a navigator, and now I am unable to add a new radschedulenavigator from the toolbox as many exceptions will be thrown:

How to show only a week in the scheduler

Hello,

I am building an application that show a school's courses, and the date they fall on is not relevant. I only need to show them on the correct day of the week that they take place. How can I customize the scheduler to only show one week and that's it (i.e. Mon-Sun) and ignore any specific week of the year.

Also, since the courses will be appointment objects on the scheduler, I am wondering if it is possible to have one appointment show up on two different days. That is to say, some courses take place on Monday AND Wednesday, so when I click on either one to move them, can I make them both respond and move together, acting as one entity?

Thanks for any help and keep up the good work Telerik.

EDIT: I figured out the first part but really could use some help with making two appointments on different days act as one.
