Question

我使用了2个控件来编辑gridview里面。它显示错误“输入字符串格式不正确”

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                fill_grd();
                fill_gender();
            }    
        }  

        public void fill_gender()
        {
            con.Open();

            SqlCommand cmd = new SqlCommand("usp_Gender_get", con);
            cmd.CommandType = CommandType.StoredProcedure;
            SqlDataAdapter da = new SqlDataAdapter(cmd);
            DataSet ds = new DataSet();
            da.Fill(ds);
            if (ds.Tables[0].Rows.Count > 0)
            {
                radiolist.DataValueField = "Gid";
                radiolist.DataTextField = "Gname";
                radiolist.DataSource = ds;
                radiolist.DataBind();
            }

            con.Close();
        }

        public void fill_grd()
        {
            con.Open();

            SqlCommand cmd = new SqlCommand("usp_Login_get", con);
            cmd.CommandType = CommandType.StoredProcedure;
            SqlDataAdapter da = new SqlDataAdapter(cmd);
            DataSet ds = new DataSet();
            da.Fill(ds);
            if (ds.Tables[0].Rows.Count > 0)
            {
                grd.DataSource = ds;
                grd.DataBind();
            }
            else
            {

                grd.DataSource = null;
                grd.DataBind();
            }
            con.Close();
        }

        protected void grd_RowEditing(object sender, GridViewEditEventArgs e)
        {
            grd.EditIndex = e.NewEditIndex;
            fill_grd();
        }

        protected void grd_RowDeleting(object sender, GridViewDeleteEventArgs e)
        {
            int id = int.Parse(grd.DataKeys[e.RowIndex].Value.ToString());
            con.Open();
            SqlCommand cmd = new SqlCommand("usp_Login_delete", con);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.AddWithValue("@Lid", id);
            cmd.ExecuteNonQuery();
            con.Close();
            fill_grd();
        }

        protected void grd_RowUpdating(object sender, GridViewUpdateEventArgs e)
        {

            TextBox TB1 = (TextBox)grd.Rows[e.RowIndex].FindControl("edittxtname");
            RadioButtonList RBL1 = (RadioButtonList)grd.Rows[e.RowIndex].FindControl("editradiolist");

            int id = int.Parse(grd.DataKeys[e.RowIndex].Value.ToString());
            con.Open();
            SqlCommand cmd = new SqlCommand("usp_Login_update", con);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.AddWithValue("@Lid", id);
            cmd.Parameters.AddWithValue("@Name", TB1.Text);
            cmd.Parameters.AddWithValue("@Gender", RBL1.SelectedValue);
            cmd.ExecuteNonQuery();
            con.Close();
            grd.EditIndex = -1;
            fill_grd();
        }

        protected void grd_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
        {
            grd.EditIndex = -1;
            fill_grd();
        }

        protected void savebtn_Click(object sender, EventArgs e)
        {
            con.Open();

            SqlCommand cmd = new SqlCommand("usp_Login_insert", con);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.AddWithValue("@Name", txtname.Text);
            cmd.Parameters.AddWithValue("@Gender", int.Parse(radiolist.SelectedValue));
            cmd.ExecuteNonQuery();
            con.Close();
            fill_grd();
        }
    }
}

不确定您的错误发生在哪里以及您粘贴的代码与您的问题无关，但无论如何我都会尝试回答。

您需要检查单选按钮的数据类型，它可能不是bool或int。您似乎是从数据库中获得的结果设置数据类型，我猜您需要通过检查存储的procudure usp_Login_get以及为radiobutton列设置的数据类型来更改数据类型。

单选按钮的输入字符串格式不正确
