我想定義在asp.net上的C＃中的GridView的嘗試捕獲，我已經使用了幾種方法，如在標籤或Java腳本顯示，但他們didn 「T工作， 感謝幫我 這裏是我的代碼嘗試捕獲不起作用在ASP.net中的GridView C＃
protected void AddNewSP(object sender, EventArgs e)
{
try
{
string Id = ((TextBox)GridView1.FooterRow.FindControl("txtId")).Text;
string PartName = ((TextBox)GridView1.FooterRow.FindControl("txtPartName")).Text;
string Coverage = ((TextBox)GridView1.FooterRow.FindControl("txtCoverage")).Text;
string SupplierName = ((TextBox)GridView1.FooterRow.FindControl("txtSupplierName")).Text;
string Status = ((TextBox)GridView1.FooterRow.FindControl("txtStatus")).Text;
SqlConnection con = new SqlConnection(strConnString);
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "insert into SupplySituation(Id, PartName, Coverage, SupplierName, Status) " +
"values(@Id, @PartName, @Coverage, @SupplierName, @Status);" +
"select Id, PartName, Coverage, SupplierName, Status from SupplySituation ORDER BY Id DESC";
cmd.Parameters.Add("@Id", SqlDbType.VarChar).Value = Id;
cmd.Parameters.Add("@PartName", SqlDbType.VarChar).Value = PartName;
cmd.Parameters.Add("@Coverage", SqlDbType.VarChar).Value = Coverage;
cmd.Parameters.Add("@SupplierName", SqlDbType.VarChar).Value = SupplierName;
cmd.Parameters.Add("@Status", SqlDbType.VarChar).Value = Status;
GridView1.DataSource = GetData(cmd);
GridView1.DataBind();
}
catch (Exception ex)
{
ScriptManager.RegisterClientScriptBlock(Page, Page.GetType(), Guid.NewGuid().ToString(), "alert('" + ex.Message.ToString() + "');", true);
}
}
private DataTable GetData(SqlCommand cmd)
{
DataTable dt = new DataTable();
SqlConnection con = new SqlConnection(strConnString);
SqlDataAdapter sda = new SqlDataAdapter();
cmd.CommandType = CommandType.Text;
cmd.Connection = con;
con.Open();
sda.SelectCommand = cmd;
sda.Fill(dt);
return dt;
}
其實是沒有任何錯誤或任何行動，當我點擊‘添加’有錯誤的數據沒有任何按鈕發生了，我除了顯示錯誤但沒有任何反應
我的前端代碼
