When i click on my submit button it will save details into database
aspx.cs code for createuser page:
protected void btnSubmit_Click(object sender, EventArgs e)
{
using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["WebGallery"].ToString()))
{
con.Open();
SqlDataAdapter da = new SqlDataAdapter();
DataTable dt = new DataTable();
string strSQL = "SELECT * FROM NewUser WHERE UserName = '" + tbName.Text + "'";
da.SelectCommand = new SqlCommand(strSQL);
da.SelectCommand.Connection = con;
da.Fill(dt);
if (dt.Rows.Count > 0) // Means first name is already present
{
lblmsg.Text = "This user is already added!";
}
else if (dt.Rows.Count == 0)
{
lblmsg.Visible = false;
string username = tbName.Text;
string pwd=tbPassword.Text;
string Confirmpwd = tbConfirmPassword.Text;
string Email = tbEmailID.Text;
string department = ddlDepartment.SelectedValue;
using (SqlCommand cmd = con.CreateCommand())
{
cmd.CommandText = "Insert into NewUser(UserName,Password,ConfirmPassword,EmailID,DepartmentName)values('" + tbName.Text + "','" + tbPassword.Text + "','"+tbConfirmPassword.Text+"','" + tbEmailID.Text + "','" + ddlDepartment.SelectedValue + "')";
cmd.Parameters.AddWithValue("@FirstName", tbName.Text.Trim());
cmd.Parameters.AddWithValue("@LastName", tbPassword.Text.Trim());
cmd.Parameters.AddWithValue("@DomainID", tbConfirmPassword.Text.Trim());

推荐答案
Amitesh，
你可以试试2件事。第一个是快速而肮脏的方法。
1.设置会话变量Session [CallerPage]。将其设置为添加用户或编辑用户，具体取决于您从哪个模块启动页面。然后在page_Load方法中设置按钮文本。在Button Click事件中，您可以检查Session变量值并根据它们创建If / else块。
2.这个涉及使用查询字符串。每当您执行response.redirect时，都会向CreateUser页面添加一个查询字符串。传递参数以检查请求是来自创建模块还是编辑模块。检查请求的来源后，您可以更改上面第一个选项中提到的按钮的文本和功能。
Amitesh,
You can try 2 things. 1st one is the quick and dirty method.
1. Set a session variable Session["CallerPage"]. Set that to "Add user"or "Edit User" depending upon which module you are launching the page from. Then set the button text in the page_Load method. In the Button Click Event you can check the Session variable value and create your If/else block according to them.
2. This one involves using the Query String. Whenever you are doing response.redirect add a querystring to the CreateUser page. Pass the parameter to check if the request is coming from Create module or Edit module. After you check the origin of request you can change the text and functionality of button as mentioned in the 1st option above.
现在我做了一些更改，它正常工作我写下来希望它为需要它的人工作
创建用户页面::
now i made some change and it work i am writing down it hope it work for some one who need it
on create user page ::
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
if (!string.IsNullOrEmpty(Request.QueryString["buttonValue"]))
{
string btnValue = Request.QueryString["buttonValue"];
if (btnValue == "Update")
{
btnSubmit.Text = "Update";
}
else if (btnValue == "Submit")
{
btnSubmit.Text = "Submit";
}
else
{
Response.Write("error");
}
}
else
{
this.btnSubmit.Text = "Submit";
}
string ID = Request.QueryString["ID"];
cmd = new SqlCommand("Select * from NewUser where ID='" + ID + "'", con);
con.Open();
da = new SqlDataAdapter(cmd);
dt.Clear();
da.Fill(dt);
if (dt.Rows.Count > 0)
{
tbid.Text = ID;
tbName.Text = dt.Rows[0][1].ToString();
tbPassword.Text = dt.Rows[0][2].ToString();
tbConfirmPassword.Text = dt.Rows[0][3].ToString();
tbEmailID.Text = dt.Rows[0][4].ToString();
ddlDepartment.SelectedValue = dt.Rows[0][5].ToString();
}
}
con.Close();
}
并在搜索用户页面上对gridview超链接进行了一些更改
and on search user page made some change in gridview hyperlink
<asp:hyperlinkfield datanavigateurlfields="ID" headertext="Edit" xmlns:asp="#unknown">
DataNavigateUrlFormatString="~/CreateUser.aspx?ID={0}&buttonValue=Update"
NavigateUrl="~/CreateUser.aspx" Text="Edit" />
</asp:hyperlinkfield>
并且可以正常工作
and it work
