GridView1.DataBind();
if (GridView1.Columns.Count > 0)
GridView1.Columns[0].Visible = false;
else
{
GridView1.HeaderRow.Cells[0].Visible = false;
foreach (GridViewRow gvr in GridView1.Rows)
{
gvr.Cells[0].Visible = false;
}
}
Step 1: Creating your first ASP.NET page using LINQ
Create a new page called Step1.aspx. Within the .aspx page add a GridView control like so:
using System;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Query;
public partial class Step1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string[] cities = { "London", "Amsterdam", "San Francisco", "Las Vegas",
"Boston", "Raleigh", "Chicago", "Charlestown",
"Helsinki", "Nice", "Dublin" };
GridView1.DataSource = from city in cities
where city.Length > 4
orderby city
select city.ToUpper();
GridView1.DataBind();
}
using System;
using System.Query;
public partial class Data_Data2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Northwind db = new Northwind();
GridView1.DataSource = from x in db.Suppliers
where x.Country == "USA"
orderby x.Country
select new {
x.CompanyName,
x.Country,
x.Products
};
GridView1.DataBind();
}
From this point onward, adding controls to the ribbon should be easy.
5. To add a tab to your ribbon control, click ‘Add Tab’. I have added three tabs; Home, Data Manipulation and Visualization. As with any control, you can change the properties of the tabs using the properties grid.
6. Once the panels have been created, click a panel. The property grid shows options for the panel. Besides ‘Add Button’, these options include ‘Add Button List’, ‘Add Item Group’, ‘Add Separator’ etc. Click the ‘Add Button’ command. A button is created. You can use the property grid to set the text, tool tip and image for the button.
7. Ribbon Button click Event.
Private Sub RibbonButton7_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles RibbonButton1.Click
MsgBox("test")
End Sub
MsgBox("test")
End Sub
