Question

我在textbox内创建了动态gridview，这是dropdown 所选索引更改时生成的，但现在我想保存textbox值在数据库中，但如何？

在那里，一行包含五个动态创建的文本框。现在，如何在每个提交按钮单击时获取这些textbox值行？

任何人都可以帮助我这个领域的新人所以指导我......谢谢

<asp:GridView ID="GridViewclass" runat="server"

您可以使用TextBox声明从GridView中读取((TextBox)row.FindControl("TextBox1")).Text值。我创建了一个Button来获取GridView到DataTable的价值。现在，您可以Insert将这些值Database转换为protected void Button1_Click(object sender, EventArgs e) { DataTable dt = new DataTable(); dt.Columns.Add(new DataColumn("RowNumber", typeof(string))); dt.Columns.Add(new DataColumn("Column1", typeof(string))); dt.Columns.Add(new DataColumn("Column2", typeof(string))); dt.Columns.Add(new DataColumn("Column3", typeof(string))); dt.Columns.Add(new DataColumn("Column4", typeof(string))); dt.Columns.Add(new DataColumn("Column5", typeof(string))); DataRow dr = null; foreach (GridViewRow row in GridViewclass.Rows) { dr = dt.NewRow(); dr["RowNumber"] = row.Cells[1].Text; dr["Column1"] = ((TextBox)row.FindControl("TextBox1")).Text; dr["Column2"] = ((TextBox)row.FindControl("TextBox2")).Text; dr["Column3"] = ((TextBox)row.FindControl("TextBox3")).Text; dr["Column4"] = ((TextBox)row.FindControl("TextBox4")).Text; dr["Column5"] = ((TextBox)row.FindControl("TextBox5")).Text; dt.Rows.Add(dr); } //this will insert data of dt into database BulkDataInsert(dt, "connectionString"); } void BulkDataInsert(DataTable dataTable, string connectionString) { try { SqlBulkCopy bulkCopy = new SqlBulkCopy(connectionString, SqlBulkCopyOptions.TableLock) { DestinationTableName = txtTableName.Text, BatchSize = 100000, BulkCopyTimeout = 360 }; bulkCopy.WriteToServer(dataTable); //Data Inserted Succesfull } catch (Exception ex) { //ex.Message) } }。请查看以下示例。

代码：

BulkDataInsert

我已经创建了一个方法DataTable，这会将完整的Database插入DataTable。您需要传递Database的{{1}}和连接字符串。
