输入每行文本框中的值后我会点击保存按钮然后我想读取gridview1上的所有值然后我可以将记录逐个插入数据库。这是我的problem.like下面我正在尝试，但价值没有得到
protected void btnPayFee_Click（object sender，EventArgs e）
{
for（int i = 0;我< gridviewCandidateDetails.Rows.Count;我++）
{
标签Fee_type =（标签）gridviewCandidateDetails.Rows [I] .FindControl（ lblFee_Type）;
文本框txtamount = （文本框）gridviewCandidateDetails.Rows [I] .FindControl（ txtAmount）;
}
}
after entering the values in text box of each row i will click save button then i want to read all the values on the gridview1 then i can insert the records into database one by one.that was my problem.like below i am trying but value is not getting
protected void btnPayFee_Click(object sender, EventArgs e)
{
for (int i = 0; i < gridviewCandidateDetails.Rows.Count; i++)
{
Label Fee_type = (Label)gridviewCandidateDetails.Rows[i].FindControl("lblFee_Type");
TextBox txtamount = (TextBox)gridviewCandidateDetails.Rows[i].FindControl("txtAmount");
}
}
推荐答案
我认为你在IsPostBack之外的Page_Load事件中绑定GridView会让你绑定IsPostBack中的代码检查它是否可行。
i think you are binding GridView at Page_Load event outside of IsPostBack put you binding code in IsPostBack check it''ll work.
