Template column

Hi,
I could add a boundcolumn to gridview using this

BoundColumn bc = new BoundColumn();
bc.DataField = "ProductsNa me";
bc.HeaderText = "Product";
gridview1.colum ns.add(bc);

What I would like to ask, how can I perform this with TemplateColumn?
I have a problem to bound template column to any object such as dropdownlist
or textbox.
TIA.
Regards,
Gun

Hi,

To create a TemplateColumn for a grid view, you need to create a
ItemTemplate class that implements the ITemplate interface. Something like
this...

public class ItemTemplate : ITemplate
{

string ControlName = "";
object DataSource = null;
//ControlName: Name of the drop down list.
public ItemTemplate(st ring ControlName,obj ect DataSource)
{
this.ControlNam e = ControlName;
this.DataSource = DataSource;
}
public void InstantiateIn(C ontrol objContainer)
{
DropDownList myDDl = new DropDownList ();
myDDl .ID = this.ControlNam e;
myDDl.DataSourc e = this.DataSource ;
myDDl.DataBind( );

//Note: If your DropDownList need not be bound to the dataSource,
// Then you cld create the list items and add then to the drop
down list.

// In your constructor for this class, you cld remove the
DataSource
//parameter.

objContainer.Co ntrols.Add(rdAn swer);
}

}
In the code behind of the form where you are having your grid view,
instantiate this class and add the column to the grid view:

TemplateField objTempCol = new TemplateField() ;

objTempCol .HeaderText = "My Template column";

ItemTemplate objTemplate = new ItemTemplate("m yDropDownList", dtSource);

//dtSource is the name of the dataTable which you wish to bind.

objTempCol .ItemTemplate = objTemplate;

MyGridView.Colu mns.Add(objTemp Col );
I hope this helps,

Hi, I am trying to implement a JS confirm dialog when a user is deleting something off my Datagrid.

I need to develop a datagrid that uses columns from a table. In addition I need two columns (checkboxes) that the user will use to indicate that this record can be closed later. The checkboxed column is not a field in the table. It is just for the purposes of the Datagrid and I do not need to store whether it was checked or not. Do I use a Template Column for this?

I am connected to an Access Database. I am reading a Yes/No field from the DB which translates back as True/False in the text field of my datagrid. I want to use a checkbox to show the value instead of text. I have set up the template column using the datagrid properties wizard. Within "Edit Template" mode I have put two checkboxes into the "Item Template"

I have a problem where my DataGrid would not maintain the ViewState of my databound rows. I finally narrowed down the problem. If my first column is a template column, the view state for the DataGrid items is not maintained on postback for some reason. I basically re-created my DataGrid again just to make sure this was indeed the problem. The ViewState was fine until I added the template column at the beginning of the Columns list. ...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
