[Vinay Singh]

Hi Friends,

How can i add dynamically add template columns to essential grid so that i can have a grid where all the rows are editable?

Hi, I have just discovered how to do this, so I pass it on... You can create them similar to how you do with regular Gridview (see http://www.codeproject.com/useritems/create_template_columns.asp). Using that as an example, you would change "TemplateField bfield = new TemplateField();", to "GridColumnDescriptor bfield = new GridColumnDescriptor();", and "GridViewRow container = (GridViewRow)txtdata.NamingContainer;" to "GridCellTemplated Container = (GridCellTemplated) txtdata.NamingContainer"
ie: Use GridColumnDescriptor where it says TemplateField, and user GridCellTemplated where it says GridViewRow. Other than that, it's the same basic concept.

Hi Vinay,

Thanks for using Syncfusion products:

You can have Template columns by creating separate Template Class. Please refer the below code snippet which illustrates to create template column:

If e.TableCellIdentity.Column.Name = "Column2" Then
Dim dropdown As Syncfusion.Web.UI.WebControls.Tools.DropDownCalendarControl = New DropDownCalendarControl()
'Here we adding the DropDownListBox programatically using ITemplate Interface
Dim mytemp As TemplateClass = New TemplateClass(dropdown)
e.TableCellIdentity.Column.EditItemTemplate = mytemp
End If
Public Class TemplateClass : Implements ITemplate
Private m_ctrlChildControl As Control = Nothing
Public Sub New(ByVal ctrlChildControl As Control)
m_ctrlChildControl = ctrlChildControl
End Sub
Public Sub InstantiateIn(ByVal container As Control) Implements ITemplate.InstantiateIn
container.Controls.Add(m_ctrlChildControl)
End Sub
End Class

Please refer the sample from the below link which illustrates the above:

Please let me know if this helps you out.
