Hi friend I am newer in ASP.NET 3.5, I want to show the value of the variable in Alert box so please give me suggestion for that. Here is my code.

public partial class WebForm1 : System.Web.UI.Page
    {
        int sum3;

        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            { 
                DataTable dTable = new DataTable("mainTable");

                DataColumn Name = new DataColumn("Name");
                dTable.Columns.Add(Name);

                DataColumn Marks = new DataColumn("Marks");
                dTable.Columns.Add(Marks);

                DataColumn Marks2 = new DataColumn("Marks2");
                dTable.Columns.Add(Marks2);

                DataColumn Total = new DataColumn("Total");
                dTable.Columns.Add(Total);

                int sum = 0;
                int sum2 = 0;

                DataRow dRow = null;
                for (int i = 0; i < 5; i++)
                {
                    dRow = dTable.NewRow();
                    dRow["Name"] = i + " - Sagar";
                    dRow["Marks"] = i;
                    sum += i;
                    dRow["Marks2"] = i + 5;
                    sum2 += i + 5;
                    dRow["Total"] = i + i + 5;
                    sum3 += i + i + 5;
                    dTable.Rows.Add(dRow);
                }

                Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "showAlert(" + sum3.ToString() + ");", true);

                //dRow = dTable.NewRow();
                //dRow["Name"] = "Total";
                //dRow["Marks"] = sum;
                //dRow["Marks2"] = sum2;
                //dRow["Total"] = sum3;
                //dTable.Rows.Add(dRow);

                aspDataGrid.DataSource = dTable;
                aspDataGrid.DataBind();
            }
        }

        protected void btn_Submit_Click(object sender, EventArgs e)
        {
            marks1.Text = "Total Marks : " + sum3.ToString();
            Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "showAlert(" + sum3.ToString() + ");", true);
        }
}

在此先感谢您.

Thanks in advance.

推荐答案

您可以尝试使用像会话一样使用会话...

在您的Page_Load事件中写入
Session ["sum3"] = sum3在For循环之后，然后您可以在
中编写此代码 按钮提交按钮

Page.ClientScript.RegisterStartupScript(this.GetType()，"alert"，"showAlert(" + Session ["sum3"] +);"，true);

You can try This Using Session Like...

In Your Page_Load Event write
Session["sum3"]=sum3 After For Loop And Then You Can write This Code in
Button Submit Button

Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "showAlert(" + Session["sum3"] + ");", true);
