Add or Remove a Column

WebDataGrid™ allows you to add or remove bound data fields and template data fields. When adding a bound field you must specify the DataFieldName to retrieve data from that field in the underlying data source. When adding a template column you can set the ItemTemplate , AlternateItemTemplate , HeaderTemplate , or FooterTemplate to define the look of that column; if you do not specify any template, the column is empty. For more information on column templates, see Column Templates.

The following code shows you how to add or remove both a bound data field and a template data field.

In Visual Basic:

' Define Columns
Dim boundField1 As New BoundDataField(True)
boundField1.Key = "CompanyName1"
boundField1.Header.Text = "Company Name1"
'Bind to CompanyName field in data source
boundField1.DataFieldName = "CompanyName"
Dim templateField1 As New TemplateDataField(True)
templateField1.Key = "TemplateField1"
templateField1.Header.Text = "Template Column"
' At this point you can set up a template for the template column
' ADD COLUMNS
Me.WebDataGrid1.Columns.Add(boundField1)
Me.WebDataGrid1.Columns.Add(templateField1)
' REMOVE COLUMNS
Me.WebDataGrid1.Columns.Remove(Me.WebDataGrid1.Columns("CompanyName1"))
Me.WebDataGrid1.Columns.Remove(Me.WebDataGrid1.Columns("TemplateField1"))

In C#:

// Define Columns
BoundDataField boundField1 = new BoundDataField(true);
boundField1.Key = "CompanyName1";
boundField1.Header.Text = "Company Name1";
//Bind to CompanyName field in data source
boundField1.DataFieldName = "CompanyName";
TemplateDataField templateField1 = new TemplateDataField(true);
templateField1.Key = "TemplateField1";
templateField1.Header.Text = "Template Column";
// At this point you can set up a template for the template column
// ADD COLUMNS
this.WebDataGrid1.Columns.Add(boundField1);
this.WebDataGrid1.Columns.Add(templateField1);
// REMOVE COLUMNS
this.WebDataGrid1.Columns.Remove(this.WebDataGrid1.Columns["CompanyName1"]);
this.WebDataGrid1.Columns.Remove(this.WebDataGrid1.Columns["TemplateField1"]);
