下面的代码根据文本框文本在excel中搜索记录并将其绑定到数据网格。但如果我尝试搜索相同的值并再次绑定它,我得到错误" DataBinding在列表中找不到适合所有绑定的行。"任何想法如何重置绑定?我尝试将formattingEnables设置为true,但它没有工作。谢谢
OleDbConnection connExcel = new OleDbConnection(_econnect);
cmdExcel.Connection = connExcel;
connExcel.Open();
DataTable dt;
DataSet ds = new DataSet();
dt = connExcel.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
OleDbDataAdapter da = new OleDbDataAdapter();
string sheetname = "BadgeID$";
cmdExcel.CommandText = "select ID, Name, Dept from [" + sheetname + "] where ID in (" + sss +")";
da.SelectCommand = cmdExcel;
da.Fill(ds);
connExcel.Close();
bsdata .DataSource = ds.Tables [0]; //error here
Invoke(new MethodInvoker(() => textBox1.DataBindings.Add("Text", bsdata, "Name")));
Invoke(new MethodInvoker(() => textBox2.DataBindings.Add("Text", bsdata, "Dept")));
答案 0 :(得分:0)
为每个文本框
调用DataBindings.Clear()
