Asked On June 25, 2012 07:52 AM UTC

Hello,
 
I need to group some column headers. On the samples i got stacked header could handle it, but i didn't get the point how to combine it with some column headers which are not grouped. I need to generate the column headers programmatically because appeared column are customized on database.
 
Please send me more documentation about how too set a Stacked header programmatically.
 
Thanks,
Salwa Omar

Hi Salwa,

Thank you for using Syncfusion products.

Your requirement of stacked headers can be achieved by adding visible columns to the GridStackedHeaderRowDescriptor. Please refer to the following code snippets: 
protected void Page_Load(object sender, EventArgs e)    {
        if (!IsPostBack)
        {                                                                                                                
            this.GridGroupingControl1.DataSource = GetData(); 
            GridStackedHeaderRowDescriptor rowDescriptor = new GridStackedHeaderRowDescriptor("row1"); // create row for stacked headers
 
            GridStackedHeaderDescriptor gshd = new GridStackedHeaderDescriptor("StackedHeader 1");  // add visible columns to the stacked header descriptor
            gshd.VisibleColumns.Add("Code");
            gshd.VisibleColumns.Add("Name");
            gshd.VisibleColumns.Add("Due");
            gshd.VisibleColumns.Add("Not Due");
            rowDescriptor.Headers.Add(gshd); 
            gshd = new GridStackedHeaderDescriptor("StackedHeader 2");
            gshd.VisibleColumns.Add("Total");
            gshd.VisibleColumns.Add("31 To 60");
            gshd.VisibleColumns.Add("91 To 120");
            rowDescriptor.Headers.Add(gshd);
            this.GridGroupingControl1.TableDescriptor.StackedHeaderRows.Add(rowDescriptor); // add created row descriptor into StackedHeaderRows
        }
    } 

For your convenience , we have prepared the sample and the same can be downloaded from the following link:

Also ,please check with the following online sample link:

Hello Eswari,
 
Thanks for your quick response. I still didn't find how to combine between stacked header columns and usual column headers.
How if i just want to group some column headers?
For example, there are 3 columns: Customer ID, First Name, Last Name.
I just need to group column header of First Name and Last Name as Customer Name. That mean Customer ID will not refer to any Stacked header.
How to define GGC columns based on that case.
 
Best Regards,
Salwa Omar

Hi Salwa,                 

Thanks for the update.

Query #1: I just need to group column header of First Name and Last Name as Customer Name. That mean Customer ID will not refer to any Stacked header.

We can achieve your requirement by adding only required columns to the stacked header rows. Please refer to the following code snippets:

            GridStackedHeaderRowDescriptor rowDescriptor = new GridStackedHeaderRowDescriptor("row1");

            GridStackedHeaderDescriptor gshd1 = new GridStackedHeaderDescriptor("Customer Name");

            gshd1.VisibleColumns.Add("Name"); 

            gshd1.VisibleColumns.Add("Code");                                        //             Customer Name stacked header

              

            rowDescriptor.Headers.Add(gshd1);

 

            GridStackedHeaderDescriptor gshd2  = new GridStackedHeaderDescriptor("Due");

            gshd2.VisibleColumns.Add("Due");

            gshd2.VisibleColumns.Add("Not Due");                                 //            Due stacked header

 

            rowDescriptor.Headers.Add(gshd2);

            GridStackedHeaderDescriptor gshd3 = new GridStackedHeaderDescriptor("Code 31-120");

            gshd3.VisibleColumns.Add("91 To 120");            

            gshd3.VisibleColumns.Add("31 To 60");                                  //            Code stacked header

        

            rowDescriptor.Headers.Add(gshd3);

            this.GridGroupingControl1.TableDescriptor.StackedHeaderRows.Add(rowDescriptor);

                            

And here Total Column is not added to any one of the stacked headers ,so it will be added as like normal column header. Please check with the following screen shot:

 

For your convenience ,we have prepared the sample and the same can be downloaded from the following link:

http://www.syncfusion.com/downloads/Support/DirectTrac/95950/StackedHeader-1906766378.zip

 Also could please give more information about your requirement. Whether you want to merge First Name and last name column headers or else you need to merge two columns (first name and last name) as single merged column ,could you please clarify this so that we can analyze based on that and provide you the better solution.

Please let us know if you have any queries.

Regards,

Eswari.S

Hi Salwa,

Thanks for your patience.

Currently we have support for Merging column header with Stacked column header.  The ‘Column header merging with stacked column header’ has been confirmed as a usability feature and has been logged as a feature report . We will implement this feature in any of our upcoming releases. We usually have an interval of at least three months between releases. The feature implementation would also greatly depend on the factors such as product design, code compatibility and complexity. We will update you when this feature has been implemented.

However, we do not provide confidential information and patches in the general forum, so could you please create a new incident such that we can easily follow up with the feature.

Let us know if you have any other queries.                                     

Regards,

Eswari.S

            GridRelationDescriptor parentToChildRelationDescriptor = new GridRelationDescriptor();

            parentToChildRelationDescriptor.ChildTableName = "MyChildTable";

            parentToChildRelationDescriptor.RelationKind = RelationKind.RelatedMasterDetails;

            parentToChildRelationDescriptor.RelationKeys.Add("Code", "Code");

 

            GridStackedHeaderRowDescriptor rowDescriptor = new GridStackedHeaderRowDescriptor("row1");

            GridStackedHeaderDescriptor gshd1 = new GridStackedHeaderDescriptor("Client Details");

            gshd1.VisibleColumns.Add("Code");

            gshd1.VisibleColumns.Add("ClientName");
