Problem with GridView sorting on date column.

I have some dates in a Rad GridView. I can never get to sort them in the correct order. I clicked on the property builder and set the sort order as Desecending for that particular date column. Is this a problem everyone face or any thing else needs to be done. How do we add a sort expression for a rad grid in winforms. I am using Q3 SP 2010. Thanks a lot for your help.

Visual Inheritance

I'm building an application with extensive visual inheritance. I have a Base RadForm. I need to have Windows7 theme application-wide. All forms inheriting this form have the correct theme but all controls that I place on the inheriting form are not picking the theme. How do I go about this? Need to manage theme for every Telerik control while using visual inheritance.

Edit: Here is a sample project. It has no theme (default blue theme) at the moment. I need Windows 7 theme (example) across the application but I want to set it through the BaseRadForm. One location to update theme application-wide.

Modify Existing Themes

I would like to modify one of the existing themes in my project. Can I extract one of the built in themes and modify it with a different name. Is this even possible? I am mainly concerned with the Radform theme.

Problems with RulerScaleSize in weekview

I have a RadScheduler (RadScheduler1) set to weekview and setting the RulerScaleSize to 15, and the ShowWeekends set to false. On the form I have a checkbox (chkShowEnds) for "Show Weekends", with the following code in it's click event.

Dim weekview as SchedulerWeekVview = Me.RadScheduler1.GetWeekView()
weekview.ShowWeekend = Me.chkShowEnds.Checked

It set the ShowWeekends property, and the RadScheduler weekends appear and disappear correctly. However, on the first click it sets the RulerScaleSize to some default setting of about 25 or so, and I can not seem to set it back to 15. I tried testing around with setting the RulerScaleSize and it seems to set to a larger value, but not smaller ones. It also seems to change the RulerScaleSize the first time, but not subsequent times.

Any help woul dbe appreciated.

ContextMenu for ListBox Item

I have a list box with some items in it. I have a ContextMenu assigned to the ListBox

I want to add logic to the "DropDownOpening" event so that the menu only displays when an ITEM is right clicked, and that is contextual for that item.

I don't seem to be able to work out how to retrieve the item over which the right click was made.

I've tried listBox.SelectedItem but that doesn't work as the right click isn't moving the selection

I've also tried listBox.GetChildAtPoint(contextMenu.DropDown.Location) - but that always returns null

Any help greatly appreciated.

Custom sorting with connected rows

Hi,

I'm using a GridView to display "Order Items".
Order Items can be arranged hierarchically by setting the Property "ParentOrderItemID" equal to the Property "OrderItemID" of the parent order item. Please not I can NOT use hierarchical grids.

What I want to do now is enabling custom sorting the following way:
If the User sorts by a certain attribute the sort algorithm must still keep together connected rows.

Say the grid has the following structure
[Order Item ID | Parent Order Item ID | Gross Value]

And the following values
[1 | null | 30]
[2 | 1 | 20]
[3 | 1 | 15]
[4 | null | 10]

If I now sort by "Gross Value", I want the sorted result to be:
[4 | null | 10]
[1 | null | 30]
[3 | 1 | 15]
[2 | 1 | 20]

How can I do it? I tried to use CustomSorting Event, but I'm stuck.

private void orderItems_grid_CustomSorting(object sender, GridViewCustomSortingEventArgs e)

{

if (this.orderItems_grid.SortDescriptors.Count == 0)

{

return;

}

int result = 0;

SD_OrderItems item1 = e.Row1.DataBoundItem as SD_OrderItems;

SD_OrderItems item2 = e.Row2.DataBoundItem as SD_OrderItems;

for (int i = 0; i < this.orderItems_grid.SortDescriptors.Count; i++)

{

string cellValue1 = e.Row1.Cells[this.orderItems_grid.SortDescriptors[i].PropertyName].Value.ToString();

string cellValue2 = e.Row2.Cells[this.orderItems_grid.SortDescriptors[i].PropertyName].Value.ToString();

if (item1.ParentOrderItem.HasValue && item2.ParentOrderItem.HasValue)

{

if (item1.ParentOrderItem.Value == item2.ParentOrderItem.Value)

result = cellValue1.CompareTo(cellValue2);

else

result = item1.ParentOrderItem.Value.CompareTo(item2.ParentOrderItem.Value);

}

else

{

result = cellValue1.CompareTo(cellValue2);

}

if (result != 0)

{

if (this.orderItems_grid.SortDescriptors[i].Direction == ListSortDirection.Descending)

{

result *= -1;

}

break;

}

e.SortResult = result;

}

Any help would be appreciated.

Thank you!

Edit Mode

Hi,

I need this functionality in my application that when user is in edit mode in a cell and then leaves the cell, then next selected cell should not be in edit mode. Means leaving an editable cell should bring the grid out of editable mode no matter user leaves the editable cell by pressing right or left key or by using mouse . Can anyone help about it? Any help would be appreciated.

Thanks

Appointment Icon

We'd like to have the ability to add icon overlays to appointments. I don't see this functionality documented anywhere, so I assume that its not implemented directly. So my next question's would be:

Are appointments drawn using their own individual OnDraw() ? If so, where do I look to grab the drawing rectangle and graphics handle for an appointment object.

If they are drawn on the schedule using the GDI graphics object of the scheduler grid, is there and accessible collection of rects for the current view, or would the control have to be extended manually. Obviously the latter option would be a last resort, since the layout logic would be a lot of work.

I know I could look at the source and find this out on my own, but where is the fun in that.

Thanks,
Chris
