Creating an Item Template for WebDataGrid™ in code requires that you implement the InstantiateIn method of the ITemplate interface. If you need to get a cell’s value within this method, you cannot access the value by simply referencing the WebDataGrid object directly.
To get a get a cell’s value, you must get a reference to the DataItem of the Container passed to the method. This DataItem is a DataRowView when the template is an Item Template. With the DataRowView, you can access the cells for that row.
The following code shows you how to get a cell’s value to set for a Label’s text when creating an Item Template in code.
In Visual Basic:
Private Class CustomItemTemplate
Implements ITemplate
#Region "ITemplate Members"
Public Sub InstantiateIn(container As Control) Implements ITemplate.InstantiateIn
Dim label1 As New Label()
label1.ID = "TemplateLabel"
' Get the cell value from the DataItem
label1.Text = DirectCast(DirectCast(container, TemplateContainer).DataItem, DataRowView)("CustomerID").ToString()
container.Controls.Add(label1)
End Sub
#End Region
End Class
In C#:
private class CustomItemTemplate : ITemplate
{
#region ITemplate Members
public void InstantiateIn(Control container)
{
Label label1 = new Label();
label1.ID = "TemplateLabel";
// Get the cell value from the DataItem
label1.Text = ((DataRowView)((TemplateContainer)container).DataItem)["CustomerID"].ToString();
container.Controls.Add(label1);
}
#endregion
}
