<blockquote class="quote"><div class="op">Quote:</div> protected void btnSave_Click(object sender, EventArgs e)
{
con.Open();
tran = con.BeginTransaction();
cmd.Transaction = tran;
string slno = null;
foreach (GridViewRow g1 in grvStudentDetails.Rows)
{
//string id = ((TextBox)g1.Cells[0].FindControl("txName")).Text;
string id = ((TextBox)g1.FindControl("TextBox1")).Text;
string name = (g1.FindControl("txAge") as TextBox).Text;
string price = (g1.FindControl("txtAddress") as TextBox).Text;
string description = (g1.FindControl("RBLGender") as Label).Text;
string query = "insert into SU_Seeker_Qualifications (Type,Join_Date,Graduated_Date,Univerisity) values(" + id + ",'" + name + "'," + price + ",'" + description + "')";
slno = id;
cmd.CommandText = query;
cmd.ExecuteNonQuery();
}
tran.Commit();
lblMessage.Text = "Records inserted successfully";
//}
con.Close();</blockquote>推荐答案
The easiest way to create and save data with DataGridView is to make a DataSet and build it by using Server Explorer to open your SQL database and add tables.
Visual Studio will generate all classes and methods needed.
You will need to learn about DataSets, TableAdapters etc.
After making the dataset, build your app and the DataSet controls will be available in your ToolBox when in designer view.
Then add your DataGridView and select the columns and link them to the dataset tables.
The designer will generate data binding and through them you can do CRUD with your data[^].
