Below line of code not taken values from grid

string temp2 = grdView.Rows[i].Cells[3].Text;

protected void btnUpdae_Click(object sender, EventArgs e)
        {
            string connection = System.Configuration.ConfigurationManager.ConnectionStrings["QuestionnaireConnection"].ConnectionString;
            using (SqlConnection con = new SqlConnection(connection))
            {
                con.Open();

                if (grdView.Rows.Count > 0) //[here the row count is zero 
                {
                    foreach (GridViewRow row in grdView.Rows) //[if I have break point here I am not getting into the loop] 
                    {
                        for (int i = 0; i < grdView.Rows.Count; i++)
                        {
                            Question qs = new Question();
                            string name = Request.QueryString["UserName"];
                            string temp1 = grdView.Rows[i].Cells[0].Text;
                            string temp2 = grdView.Rows[i].Cells[3].Text;

                            SqlDataAdapter da;
                            da = new SqlDataAdapter("UPDATE Questionnaire_UserAnswers SET Comments='" + temp2 + "' WHERE Question_ID=" + temp1 + "", con);
                            DataSet ds = new DataSet();

                            da.Fill(ds);
                            grdView.DataSource = ds;
                        }

                        grdView.EditIndex = -1;
                        ShowGridBindData();
                        lblmessage.Visible = true;
                        lblmessage.Text = "Record Updated Successfully";
                    }
                }

推荐答案

使用数据键更好地获取网格值

gridview.DataKeys(e.RowIndex).Values(0).ToString()

use data keys is better to get grid values

gridview.DataKeys(e.RowIndex).Values(0).ToString()

这是查找控件和文本值的方法
在这里我们可以使用Dropdown或任何控件

GridviewRow行；

This is the way to find Control And Text value
here we can use Dropdown or any control

GridviewRow row;

string textBoxText = _
         ((TextBox)row.FindControl("TextBox1")).Text;

使用findbycontrol
如果您使用模板字段

use findbycontrol
if you use template fields
