Question: How do I determine what object I clicked on in the grid

Hello,

There was a function called hittest that I used in another grid that I worked with that allowed me to determine if a cell had been clicked on or a column or row header had been clicked on. Does this grid have such a function?

Thanks

Issue with scrollintoview

Hi,

telerik: 2009.3.1322.35
.net 4.0 beta 2

When I follow the steps below I get an error:
1. Set a filter on gridviewdatacolumn
2. Filtered items set contains a certain dataitem
3. Change this dataitem such that it no longer belongs to filtered items
4. After the change I scroll into view:

    
            GridView.SelectedItem = _dataItem 
        
                            If GridView.SelectedItem IsNot Nothing Then 
        
                                GridView.ScrollIntoView(GridView.SelectedItem) 
        
                            End If

Now I get the following error:

DataSet binding

Hi,

I have no problems binding my classes to the GridView. But when I attempt to bind a linq filtered DataSet table

    
            IEnumerable<DB.MyDataSet.XXXRow> filter = dataset.XXX.Take(10);
GridView.ItemsSource = filter;

all I see in GridView is rows with no text in them, when I enter edit mode in a row, the missing text is suddenly right there. It goes invisible again when edit mode is canceled.

This is how I setup the header:

    
            Telerik.Windows.Controls.GridViewDataColumn columnName = new Telerik.Windows.Controls.GridViewDataColumn();          

columnName.DataType = typeof(string);
columnName.UniqueName = "YYY";
columnName.Header = "sweet YYY";

any ideas what is going on?

Thanks

Jiri

Stacked Bar Chart Bars Sometimes Levitate

Hello,

I created a stacked bar chart with 4 data series. When I display the chart I sometimes get floating bars, I disabled two of the data series (since they rarely have data) and the one series still has a floating stacked bar. I attached a screenshot to make the situation more clear. I am not sure why my bars are floating. Note that I also have other bar charts that are created the exact same way but they never have a floating data series.

Question: About Refreshing grid contents by executing stored proc again

Hello,

I execute a proc and load its contents into a dataset, which I than associate with the grid. That works fine.

If I than repeat this process in order to update the grid's contents the changes do not show up on the grid unless I close the app and open it up again.

To get around this problem I execute this command (gridname.itemssource = null) to break the association between the grid and the dataset. I than run the proc again , load the dataset , and than associate the grid with the dataset again. This works.

Is this what I am suppose to do?

Conditional border for indent cell

Hi all,

I applied conditional properties to GridViewGroupRows via the Level property and Property Triggers - however I can't seem to find a similar property for IndentCells.

Is it possible to set conditional properties for the indent cell at different levels? Ie. I would like to have no borders for the indent cells at level 0, 1 - however I would like a right border for the rows in level 2. How would I do this?

Regards,

Tim.

Thanks in advance,

Use of Telerik Controls in ActiveX for use in SAP SDK

Hi,

We are trying to use the Telerik controls for development of applications that can integration into SAP Business One. In order to do that, we wanted to use the control into an ActiveX object, and then use that object inside of the SAP SDK on custom forms. We have been able to get the Telerik control into an ActiveX DLL, the use that DLL on a Windows form.

However, when we try to use the same ActiveX DLL inside of the SAP System and try to set the ClassID property of the SAP SDK ActiveX object, which requires the ProgID or GUID of the ActiveX object, and pass the reference, the .NET program is throwing an exception.

If anyone has taken this approach with a Telerik control (through an ActiveX DLL) in an environment like SAP Business One, and can assist in what could be causing this issue, please post any pertinent information.

Thanks.

ShowDialog and XBAP

When I call ShowDialog() on a RadWindow in a standard WPF application then ShowDialog returns when the user closes the RadWindow. When I'm running my application as XBAP in the browser then ShowDialog returns immediately.

Is this an intentional behaviour? If so, what do I have to do to display a modal dialog in a XBAP environment?

Regards,
Michael
