Using the Template Class in DataList

The following steps will take us through to use the above created MyTemplate class to create header, item and footer templates dynamically.

1.    Create a DataList object.

2.    Create an instance of our created dynamic template class by passing the ListItemType corresponding to the type of the item.

3.    Assign the instance to the datalist template property like:

Listing 3: DataList Templates

DataListObject.HeaderTemplate = new MyTemplate(ListItemType.Header);
DataListObject.ItemTemplate = new MyTemplate(ListItemType.Item);
DataListObject.FooterTemplate = new MyTemplate(ListItemType.Footer);

The below code contains code that uses the MyTemplate class to build the DataList dynamically. I have added a PlaceHolder in the WebForm which will hold the dynamically created DataList after the execution.

Listing 4: Using TemplateClass

protected void Page_Load(object sender, EventArgs e)
for (int i = 0; i < dsArticles.Tables.Count; i++)
            if (dsArticles.Tables[i].Rows.Count > 0)
                DataList dlArt = ConstructDL(
                dlArt.DataSource = dsArticles.Tables[i];
public DataList ConstructDL(string CategoryName,int Count)
        DataList dlArt = new DataList();
        MyTemplate headTemplate = new MyTemplate(ListItemType.Header);
        headTemplate.CategoryName = CategoryName;
        dlArt.HeaderTemplate = headTemplate;
        dlArt.Width = Unit.Percentage(100);
        dlArt.ItemTemplate = new MyTemplate(ListItemType.Item);
        MyTemplate footerTemplate = new MyTemplate(ListItemType.Footer);
        footerTemplate.NoOfArticles = Count.ToString();
        dlArt.FooterTemplate = footerTemplate;
        return dlArt;

In the above code, phArticles is the PlaceHolder id. Thus, we have created the DataList dynamically and now we will move on to the implementation of dynamic GridView.

Title: If items dissapear in postback   
Name: TiagoReil

I had to do something like this, and had lots of problems. First of all, when you do a postback, you loose all the dinamic templates. Not databounts added dinamically, but only the ones that are templates disapear always. So I run the code on every postback. But then the events in the grid, that are loaded dinamically, started acting strange. Runing events that had already run, etc.

The solution and correct way to do this is to add all the code for adding columns on the PreInit event. Thats the correct place to add the creation of the columns.
