此c#代码在wpf框架中运行良好。现在我需要asp.net中的这段代码。我使用的是GridView而不是DataGrid。我需要做什么改变？
这是我的c#代码：
DataRowView SelectedRowValue = (DataRowView)dataGrid1.SelectedValue;
byte[] ImageBytes = (byte[])SelectedRowValue.Row.ItemArray[1];
MySqlCommand cmd2 = new MySqlCommand("INSERT INTO Images (Image) VALUES (@ImageSource)", con);
cmd2.Parameters.Add("@ImageSource", MySqlDbType.Blob, ImageBytes.Length).Value = ImageBytes;
cmd2.ExecuteNonQuery();
您可以使用c#使用Grid_RowUpdating事件
protected void oGridView_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
GridViewRow row = (GridViewRow)GridView1.Rows[e.RowIndex];
Label lblID = (Label)row.FindControl("Label1");
TextBox txtImage = (TextBox)row.Cells[0].Controls[0];
//........
Then Update Command for MySQl which You are using//
MySqlCommand oMySqlCommand = connection.CreateCommand();
oMySqlCommand.CommandText = ""update detail set
Image='"+txtImage.Text+"'where id='"+userid+"'";
connection.Open();
command.ExecuteNonQuery();//.......etc//
GridView1.EditIndex = -1;
}
