SelectCommand="SELECT TOP 4[Id], [Date], [Title], [PictureUrl], [Description],[VideoUrl], [Author], [Type] FROM [News] ORDER BY [Date] DESC , [Id] DESC">
</asp:SqlDataSource>
I would like to use a button which will enables the Datalist to display 8items.
Well, the problem is with your query itself. You are asking for only the top four records. Why do you want 4 empty rows in your datalist? If you want 8, then SELECT TOP 8. Am I understanding you correctly or are you trying to do something else?
But I want to have a button "More Titles" when clicked on this button, the Datalist will display 8Items instead of 4items
Hello,
I think since you wanna dynamically change your SQL statement——you have to dynamically databind to the data presentation control by referring this below：
1）Remove using DataSource first.
2）Then you should dynamically data-binding in the button's click：
using(SqlDataAdapter adapter = new SqlDataAdapter("select TOP 8 * from xxx","connection string here"))
{
DataTable dt = new DataTable();
adapter.Fill(dt);
//Do binding……
}

Hi
I'm displaying 4items on a datalist using the SqlDataSource
<asp:SqlDataSource ID="SqlDataSource2" runat="server"
ConnectionString="<%$ ConnectionStrings:News %>"
SelectCommand="SELECT TOP 4[Id], [Date], [Title], [PictureUrl], [Description],[VideoUrl], [Author], [Type] FROM [News] ORDER BY [Date] DESC , [Id] DESC">
</asp:SqlDataSource>
I would like to use a button which will enables the Datalist to display 8items.
Any idea about how to do this?
protected void MoreTitle_Click(object sender, EventArgs e)
{
// any codes here?
}
