Customizing Columns and Baseline Variance

[Mehmet Kucuk]

Hi,

I am trying to customize the columns in the GanttControl but when I do, it stops calculating the variances,

I want to hide some columns basically, but I still want to see the Finish Variance. My task details' properties for Finish and BL Finish are filled.

This is the way I am customizing the columns;

ganttChart.LoadVarianceTableView();

ganttChart.ShowAddNewColumn = false;

ganttChart.GanttGrid.Columns.RemoveAt(2);

ganttChart.GanttGrid.Columns.RemoveAt(2);

ganttChart.GanttGrid.Columns.RemoveAt(3);

ganttChart.GanttGrid.Columns.RemoveAt(4);

ganttChart.GanttGrid.Columns.RemoveAt(6);

ganttChart.GanttGrid.ReadOnly = true;

When I comment out the column removals, the variances are being calculated. I tried to go over the CustomizedTable sample but couldnt solve the problem.

I am guessing that the BL variances are calculated based on the specific indexes instead of mapping names.

Thanks in advance for any help.

I actually found a way around by simply setting 0 for the width of the columns that I want to remove;

ganttChart.LoadVarianceTableView();

ganttChart.GanttGrid.Columns[2].Width = 0;

ganttChart.GanttGrid.Columns[3].Width = 0;

ganttChart.GanttGrid.Columns[5].Width = 0;

ganttChart.GanttGrid.Columns[7].Width = 0;

ganttChart.GanttGrid.Columns[10].Width = 0;

ganttChart.ShowAddNewColumn = false;

ganttChart.ItemsSource = tasks;

But I would still appreciate if I could learn how to use insert/remove columns without losing functionality.

Hi Mehmet, 

Thanks for contacting Syncfusion support. 

If we insert and remove columns  from the Columns collection, the baseline variance values are getting displayed correctly in the grid. We have prepared the sample based on this scenario and you can download the sample from the following location. 

baseline_variance 

If you still able to reproduce the problem, please revert to us by reproducing the issue in provided sample which will be helpful to provide you a solution. 

Regards,

Hi Rachel,

Your help is much appreciated. However I couldn't run the sample properly.

First, there was an out of range error in the GanttGrid_Loaded event. I corrected that one but now I am getting a null reference error in Syncfusion.Gantt.Wpf.dll.  It only works when I comment out the loaded event but then obviously the gantt grid has the standard variance table view.

private void GanttGrid_Loaded(object sender, RoutedEventArgs e)

        {

            var collection = (Gantt.GanttGrid.Columns as ObservableCollection<GridTreeColumn>);

            for(int i=0;i</*=*/Gantt.GanttGrid.Columns.Count;i++)

            {

               

                if ((Gantt.GanttGrid.Columns[i] as GridTreeColumn).MappingName == "Id")

                {

                   collection.Remove(Gantt.GanttGrid.Columns[i]);                    

                }

                else if ....

About the Baseline, I want to add one more query.

As an ASP.NET control, gantt has a capability of rendering another bar in the chart to represent baseline. ( http://asp.syncfusion.com/demos/web/gantt/baseline.aspx )

Is there a way of doing so for WPF? I have checked the WPF API Reference but couldn't find the same properties. I found a property for TaskDetails, "Baseline" which is set&get a double value but I couldn't understand what does this property actually do.

Thanks for any help.

Kind Regards.

Hi,

As suggested, I am trying to upgrade my product version to 14.1.0.46.

Currently, I am using Essential Studio 14.1.0.41. 

I downloaded the Link Install file of 14.1.0.46 (as there is no Essential Studio Version for that). 

I installed it to the following folder "C:\Program Files (x86)\Syncfusion\Link Install\14.1.0.46" as suggeted by the app. 

So, now I have "C:\Program Files (x86)\Syncfusion\Essential Studio\14.1.0.41\" and "C:\Program Files (x86)\Syncfusion\Link Install\14.1.0.46". However, when now I try to drag and drop a control, I am receiving an error.

Could you please give me a walkthrough for how to upgrade from 14.1.041 to 14.1.046? Should I just swap the files from .46 folder to .41 folder?

Kind Regards.

Hi,

I am sorry but this is not working at all on my end. I am a newbie developer and find this service pack upgrade unnecessarily complicated.

I installed the Link Install version of service pack 14.1.0.46. All good. It installed successfully to the following folder: C:\Program Files (x86)\Syncfusion\Link Install\

Then, I ran the assembly manager located in: C:\Program Files (x86)\Syncfusion\Link Install\14.1.0.46\Utilities\Assembly Manager

And, it didn't work. Because the manager is looking in the folder: C:\Program Files (x86)\Syncfusion\Essential Studio\14.1.0.41\precompiledassemblies\14.1.0.46\

Ok, so I copied the content in: C:\Program Files (x86)\Syncfusion\Link Install\14.1.0.46\precompiledassemblies to: C:\Program Files (x86)\Syncfusion\Essential Studio\14.1.0.41\precompiledassemblies\14.1.0.46\

Ran the assembly manager, and now it worked.

I checked my GAC folder and found this: C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Syncfusion.Gantt.Wpf\v4.0_14.1460.0.46__3d67ed1f87d44c89 so i guess I am on the right path.

I changed every reference in my application bin to the upgraded .dll and .xml from: C:\Program Files (x86)\Syncfusion\Essential Studio\14.1.0.41\precompiledassemblies\14.1.0.46\

Then I ran the project migration tool in: C:\Program Files (x86)\Syncfusion\Essential Studio\14.1.0.41\Utilities\Project Migration

In the Essential Studio version, I entered: "14.1.0.46" and performed the action.

I opened my project and saw that all the syncfusion references are now unresolved.

Can you please advise me in a more detailed fashion on how to upgrade to the new service pack? A step-by-step walk-through would be much appreciated. I think this could be beneficial for other users as well.

Thank you so much for your time.

Kind Regards.

[Mehmet Kucuk]

An Update:

I think the problem is with the project migration tool. I opened my .cdproj file with a notepad and manually changed the versions in my references and now they are working.

However, when I ran Syncfusion Reference Manager in Visual Studio 2015, I still cant see version 14.1.0.46. There is only 14.1.0.41.

Kind Regards.
