    tb.Enabled = false;
    tb.Text = ViewState["IE_Vehiclecode"].ToString();
}
tb.ID = "txtbox" + i.ToString();
rfv.ID = "rfvvalid" + i.ToString();
rfv.ControlToValidate = tb.ID;
rfv.ErrorMessage = "*";
rfv.ForeColor = System.Drawing.Color.Red;
rfv.ValidationGroup = "required";
tb.Style.Add("Width", "120px");
tb.Style.Add("Height", "15px");
tb.Attributes.Add("runat", "Server");
//c.Controls.Clear();
//c.RowSpan
grdviewvechicleDetails.Controls.Add(tb);
c.Controls.Add(tb);
c.Controls.Add(rfv);
i++;

在提交按钮中单击我无法找到它显示为null的文本框ID

in submit button click i was not able the find the text box id it was showing as null

foreach (GridViewRow grv in grvInsuranceDetails.Rows)
            {
                int i = 0;
                   TextBox txt = (TextBox)grv.FindControl("txtbox1");
                    foreach (TableCell c in grv.Cells)
                    {
                        TextBox txt1 = (TextBox)c.FindControl("txtbox0");
                        string grdid = grvInsuranceDetails.Rows[grv.RowIndex].Cells[i].Text.ToString().TrimEnd();
                        i++;
                    }
            } 

有人可以帮我吗？



在此先感谢！

推荐答案

您是在回发时（以及点击事件触发之前）重新绑定GridView吗？如果不这样，动态添加的控件将不会成为控件树的一部分，并且FindControl将无法找到它们。

Are you rebinding the GridView on postback (and prior to the click event firing)? The dynamically added controls won't be a part of the control tree if you don't and FindControl won't be able to find them.
