Grid is not updating Text on modifying the bound observable collection

Hi,

I have a Grid which is bound to an observable collection. The first column is a Combobox. Based on the selection in the first column, I need to change the values of the remaining columns in the same row. I tried to modified the Observable collection but the text of remaining columns are not getting changed. But if I click on each of the remaining columns, text is getting updated. Please help.

Thanks and Regards,
Norbert John

Problem configuring X axis manually

Hello Everyone,

I am creating a chart to display real-time data that is "polled" every 5 seconds. Additionally, my chart can contain multiple data series all of which will be spline. If I let the chart auto calculate the X axis bounds and ticks, it is extremely slow in displaying initial values. So I want to set the X axis manually. Here is the code I have so far:

    
            radChart1.DefaultView.ChartArea.AxisX.LayoutMode = AxisLayoutMode.Normal;  
        
            radChart1.DefaultView.ChartArea.AxisX.IsDateTime = true;  
        
            radChart1.DefaultView.ChartArea.AxisX.DefaultLabelFormat = "T";  
        
            radChart1.DefaultView.ChartArea.AxisX.AutoRange = false;  
        
            DateTime MinVal = DateTime.Now;  
        
            DateTime MaxVal = MinVal + TimeSpan.FromSeconds(UpdateInterval * (NumDataPoints + 1));  
        
            radChart1.DefaultView.ChartArea.AxisX.AddRange(MinVal.ToOADate(), MaxVal.ToOADate(), 1.0);  
        
            radChart1.DefaultView.ChartArea.AxisX.Step = 0.05;  
        
            radChart1.DefaultView.ChartArea.AxisX.LabelStep = 1;

Note that the default value for UpdateInterval is 5 and NumDataPoints is 10

However, using the above code, I only get two ticks on the X axis. What I really want is that the number of ticks should be the same as NumDataPoints and they should be equally distributed between the Min and Max of the X axis range. How can I achieve that? I have tried playing around with Step and LabelStep values but did not get anything different.

Any help would be greatly appreciated.

Thanks

Inheriting colors from GridView when exporting

Hi. I'm trying to implement Excel exporting on a RadGridView (it's been pretty frustrating btw), and I've noticed you have to manually set each row, group and header style when doing so. Is there any way I can export the grid with the appearance it's already got in my application?

Thanks.

PS: I'd really recommend for a next release a makeover of the grid's exporting capabilities, given the fact they're so limited right now.

HeaderRow and GridViewScrollViewer

Hi guys,

I have a requirement where I need to have VerticalScrollBar appeared right under the column headers.
Well, I was able to archive that by changing the ControlTemplate for the GridView where I moved GridViewHeaderRow to outside of the ScrollViewer. Everything seems to work just fine. Next I wanted to have a star sized columns and that's where I am having a little problem. I need my last Column Header to use all the remaining space; however there still a space of VerticalScrollBar's width on the right. It's not a filler column; simply DataCellsPresenter inside GridViewHeaderRow does not stretching its content all the way. How do I fix this.

Attached is sample pick.

Thanks,

GridView

Populating with a six level hierarchy

Hello there,

Do the gridview support making a six level hierarchy in an easy way?

Right now I'm setting my top data set as ItemsSource and then do a lot of child table definitions. To be able to remove GroupPanel and ColumnHeaders in my child nodes I'm listening on the DataLoading event casting the sender to a GridViewControl. For getting all the child column I have set the AutoGenerateColumns property to true. But I need to remove some of them so I also listening for AutoGeneratingColumn event. Doing this seems a little bit odd!

Another question is if I'm able to update the data at the bottom node in the gridview from a database without destroying the expanded hieararch made by the user?

Am I correct in my assumption that the gridview only support a two level hierarchy in a good manner.

Best wishes from Johan
