How to change the group area text?

If you change your code behind this way, you will get this behaviour:

if (!IsPostBack)

{

this.WebHierarchicalDataGrid1.GridView.Columns.Clear();

this.WebHierarchicalDataGrid1.GridView.ClearDataSource();

this.WebHierarchicalDataGrid1.GroupingSettings.GroupedColumns.Clear();

BoundDataField col1 = new BoundDataField();

col1.DataFieldName = "ClaimNumber";

col1.Key = "ClaimNumber";

col1.Header.Text = "Claim Number";

this.WebHierarchicalDataGrid1.GridView.Columns.Add(col1);

BoundDataField col2 = new BoundDataField();

col2.DataFieldName = "PatientLastName";

col2.Key = "PatientLastName";

col2.Header.Text = "Patient Last Name";

this.WebHierarchicalDataGrid1.GridView.Columns.Add(col2);

BoundDataField col3 = new BoundDataField();

col3.DataFieldName = "PatientFirstName";

col3.Key = "PatientFirstName";

col3.Header.Text = "Patient First Name";

this.WebHierarchicalDataGrid1.GridView.Columns.Add(col3);

BoundDataField col4 = new BoundDataField();

col4.DataFieldName = "SSN";

col4.Key = "SSN";

col4.Header.Text = "SSN";

this.WebHierarchicalDataGrid1.GridView.Columns.Add(col4);

BoundDataField col5 = new BoundDataField();

col5.DataFieldName = "InjuryDate";

col5.Key = "InjuryDate";

col5.Header.Text = "InjuryDate";

col5.DataFormatString = "{0:dd/MM/yyyy}";

this.WebHierarchicalDataGrid1.GridView.Columns.Add(col5);

BoundDataField col6 = new BoundDataField();

col6.DataFieldName = "Value";

col6.Key = "Value";

col6.Header.Text = "Value";

this.WebHierarchicalDataGrid1.GridView.Columns.Add(col6);

}

this.WebHierarchicalDataGrid1.DataKeyFields = this.WebHierarchicalDataGrid1.GridView.Columns[0].Key;

this.WebHierarchicalDataGrid1.GridView.DataKeyFields = this.WebHierarchicalDataGrid1.GridView.Columns[0].Key;

this.WebHierarchicalDataGrid1.DataSource = GetData();

this.WebHierarchicalDataGrid1.DataBind();

this.WebHierarchicalDataGrid1.RefreshBehaviors();

//this.WebHierarchicalDataGrid1.DataSource = GetData();

//this.WebHierarchicalDataGrid1.DataBind();

}

HTML:

<ig:WebHierarchicalDataGrid ID="WebHierarchicalDataGrid1" AutoGenerateColumns="false" StyleSetName="Ferrero"

runat="server" Height="100%" Width="100%"

OnGroupedRowInitialized="WebHierarchicalDataGrid1_GroupedRowInitialized">
