[英]How to Dynamically add Table rows
我试图在按钮单击时在表行中添加值。 它适用于数据库,但不适用于网页。 它会覆盖页面的最后一行。
如何在每次单击按钮时生成新行。
这是我的按钮点击代码-
protected void Page_Load(object sender, EventArgs e)
{
tblAdd.Visible = false;
Label1.Visible = false;
//Label2.Visible = false;
}
protected void btnSave_Click(object sender, EventArgs e)
{
int count = 1;
if (Page.IsValid)
{
TableRow NewRow1 = new TableRow();
//1st cell
TableCell NewCell1 = new TableCell();
//new checkbox
CheckBox newCheckBox1 = new CheckBox();
// adding lebel into cell
NewCell1.Controls.Add(newCheckBox1);
// adding cells to row
NewRow1.Cells.Add(NewCell1);
//2ed cell
TableCell NewCell2 = new TableCell();
Label newLabel1 = new Label();
count = count + 1;
newLabel1.Text = txtName.Text;
newLabel1.ID = "label" + count;
NewCell2.Controls.Add(newLabel1);
NewRow1.Cells.Add(NewCell2);
//adding row into table
tblLanguages.Rows.Add(NewRow1);
btnAdd.Visible = true;
btnDelete.Visible = true;
Label2.Visible = true;
Label2.Text = "Successfully Added";
add();
}
txtName.Text = "";
}
public int add()
{
string strcon = ConfigurationManager.ConnectionStrings["Dbconnection"].ConnectionString;
SqlConnection sqlConnection = new SqlConnection(strcon);
SqlCommand command = new SqlCommand("hrm_AddLanguages", sqlConnection);
command.CommandType = CommandType.StoredProcedure;
command.Parameters.Add("@Name", SqlDbType.VarChar).Value = txtName.Text;
command.Parameters.Add("@CreatedOn", SqlDbType.DateTime).Value = DateTime.Now;
command.Parameters.Add("@UpdatedOn", SqlDbType.DateTime).Value = DateTime.Now;
command.Parameters.Add("@CreatedBy", SqlDbType.BigInt).Value = 1;
command.Parameters.Add("@UpdatedBy", SqlDbType.BigInt).Value = 1;
command.Parameters.Add("@IsDeleted", SqlDbType.Bit).Value = 0;
sqlConnection.Open();
return command.ExecuteNonQuery();
}
请帮我。
