Hello

I need to implement this scenario:

There is int in the data item that represents value in data base table.

In the grid there is data column that binding to this int.

When the Create Cell Element method called I take the int and go to service that return the value from DB.

This is the issues:

1.

 I need to show the string that returns form the service in this column instead of the int.

This is extra data that not in the data item of the column.

How can I add this data to the column?

2.

The filter knows the int in the data member binding.

 I need to give the filter the same data that shown in the column.

 

I don’t want to use combo box column.

What is the solution for this scenario?

Best regards

Ehud

 

I have a number of children property on each of my items in the TreeGridList, this list is currently an ObservableCollection. 

If I have the children expanded in the grid, and then transition the number of children on the parent to 0 through the grid, the collection changed notification coming from the ObservableCollection causes the grid to try to revert the change that is under way (changing the number of children to 0).  I am not sure how to resolve this (keep the 0 child count).

I have a very simple sample project but am not sure how to attach it.  (I pasted the view item below).

reproduction steps - launch application, change child count on an item to 3, expand item, change child count to 0 (notice that the number of children remains 3).

Thanks for your help..

Hi,

I'm currently evaluating Tererik WPF RAD controls for use on a future large scale project. Those most samples work as expected but the gauge dashboard sample always crashes regardless.

I'm using build RadControls_for_WPF40_2010_3_1110_Trial

My design environment is VS2010 using .NET4 framework on XP Pro SP3. The graphics is standard onboard intel chipset and has the latest drivers and all patches applied including silverlight patches.

The following exception occurs when running the supplied compiled sample app:

System.NullReferenceException was unhandled
  Message=Object reference not set to an instance of an object.
  Source=Gauge

I am evaluating WPF controls but I'm unable to recommend them if the provided samples don't run, apart from that the controls look really good.

Any feedback would be appreciated,

Norman.

Is there some way I can intercept a user's click of the red X (close) button on a criteria within the rad data filter? In particular, I'm trying to determine whether or not I can handle a click on the root-level X button in order to warn the user that their data filter will be cleared out by proceeding.

I am having a hard time having my FileExplorer Treeview maintain item selection when I click on another control.  You can see this happening by clicking 'Open FileExplorer Window' and then clicking on the textbox below the Treeview.

Im going to reference the same control that I have been using for various examples with you guys.
Please download it here  Copy the foo directory to C:\

Thanks again for your continued support!

I would like to save the index of the active view so that the user comes back to the same view the next time he/she uses the schedule view.

Thanks,
Rod

Hi,

I have several usercontrol diplay on information layer (HotSpot). I need to interact with these user controls, for exemple changing color fo the control. How can I do this?

Thanks!

I am trying to implement a selection mechanism to select a series of MapShapes from a particular layer.  The stategy that I use is to create a MapPath and set the Data item to be a MapGeometryGroup.

For each shape that is selected (and these are either MapPaths or MapPolygons), I create a MapGeometry from it, and then add that geometry to the group.

Works perfectly!

However, I now need to shrink each of the geometries by 10%, and align them in the center of the original shapes.  So for each of the MapGeometries I have added a Transform


I have two problems;

1. The translate doesn't take me to the correct origin to apply the ScaleTransform so that I don't move my X, Y coordinates in the scale
2. If I add two shapes to the Group, then the transform seems to be applied to both MapGeometries in the Group, rather than applying just to itself.

Any help would be appreciated

Thanks
Simon

I want to be able to move to the next cell or row although the current cell has validation errors but I cant seem to find a property to override the default behaviour. To be specific: I want to display validation but not restrict the user from moving to the next cell or row (or leaving the grid for that sake).

1) Is there a way to override this default behaviour?
2) If no, are there any plans to support this scenario?

Hi,
I have  a line graph and i need my x axis to start with 1 instead of 0 and also is it possible to have a grid behind the plot points? Is that possible and how do you that please?
Any help would be great.


Thanks

Simon
