Dot Net Implementations

  Create a Link Button using Template Field.  Create an event of link button- Steps- 1. Select the Grid View.  2. Go to source. 3. Create the Event 'OnClick' in Link Button's attribute.  4. Create the Event of link button in code window-  protected void send_click(object sender, EventAgrs e) { // activate the control GridViewRow gr1 = ((LinkButton)sender.NamingContainer as GridViewRow;  // find control  LinkButton l1 = (LinkButton) gr1.FindControl("lb1"); ; Session["name"] = gr1.Cells[0].Text; Session["amu"] =  gr1.Cells[1].Text;  Response.Redirect("NextPage.aspx"); } 2. We have to call the Session in the page_load event of NextPage-  protected void Page_load(object sender, EventArgs e) { Label1.Text = (string) Session["name"]; Label2.Text = (string) Session["amu"]; }

  1. display all records of data base-   Query- select * from Chitransh_stu;  2. display the name whose age is lesser than 20- Query-   SELECT name FROM     Chitransh_stu WHERE  (age < 20);  3. display the marks of students with their names whose section is BCA- Query-  SELECT name, marks FROM     Chitransh_stu WHERE  (course = 'BCA'); 4. Delete a record from the table whose address is jabalpur- Query-   DELETE FROM Chitransh_stu WHERE  (address = 'jabalpur'); 5. Delete the records whose marks are greater than 60- Query-   DELETE FROM Chitransh_stu WHERE  (marks < 60); 6. Insert a new record in the table- Query-   INSERT INTO Chitransh_stu                   (roll, name, age, course, address, marks) VALUES (10, 'sidhharth', 34, 'mca', 'jabalpur', 89); 7.

1. Took File Upload control, Button, Image button control,  Label (First Page) [Browse your desired file > Click on Upload Button > Image will be shown in Image Button Control  ]  Inside the event of ImageButton QueryString is defined.  CODING- 2. When we click on it then the next page will be shown Image ,Using QueryString-  (Next Page) Image control will be used-  Inside page_load event we will call QueryString.

    Write a code for this-                                                                    1.Registration.aspx- Coding of SUBMIT button- using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class Registration : System.Web.UI.Page {     protected void Page_Load(object sender, EventArgs e)     {     }     protected void Button1_Click(object sender, EventArgs e)     {         Response.Redirect("Login.aspx?name=" +TextBox1.Text + "&email=" + TextBox2.Text + "&mobile=" +TextBox3.Text + "&pass=" +TextBox4.Text + "&city=" + DropDownList1.Text);      } } 2.
