HERE IS MY ASP.NET CODE
public partial class Admin : System.Web.UI.Page
{
SqlConnection con = new SqlConnection("server = yamma; uid = sa; pwd = /*-; database = rigo");
SqlCommand cmd;
SqlDataAdapter da = new SqlDataAdapter();
DataTable dt = new DataTable();
public static DataTable dtDefault = new DataTable();
public Int64 n;
protected void Page_Load(object sender, EventArgs e)
{
if(!Page.IsPostBack)
{
showdata();
//string EditID = Request.QueryString["EditId"];
}
}
public void showdata()
{
if (con.State == ConnectionState.Closed)
{
con.Open();
}
cmd = new SqlCommand("RigoSelect", con);
cmd.CommandType = CommandType.StoredProcedure;
da.SelectCommand = cmd;
da.Fill(dt);
da.Fill(dtDefault);
gvdetails.DataSource = dt;
gvdetails.DataBind();
}
protected void btnadd_Click(object sender, EventArgs e)
{
ListBox1.Items.Add(txtoption.Text); //to select data from textbox to listbox
}
protected void btndelete_Click(object sender, EventArgs e)
{
string remove = ListBox1.SelectedItem.Text;
ListBox1.Items.Remove(remove);
////clear all items in listbox
//listBox1.Items.Clear();
}
protected void btnselect_Click(object sender, EventArgs e)
{
txtcorrectoption.Text = ListBox1.SelectedItem.Text;
}
protected void gvdetails_RowCommand(object sender, GridViewCommandEventArgs e)
{
//private Int64 n;
//for(int i=0;i<=n;i++)
//{
int id = int.Parse(gvdetails.Rows[0].Cells[0].Text);
DataRow[] dr = null;
dr = dtDefault.Select("ID = '" + id + "'");
txtquestion.Text = dr[0]["question"].ToString();
txtoption.Text = dr[0]["options"].ToString();
//}
showdata();
}
protected void gvdetails_RowEditing(object sender, GridViewEditEventArgs e)
{
// when boundfied is exist in gridview then id can get....thisway
//int id = int.Parse(gvdetails.Rows[e.NewEditIndex].Cells[0].Text);
////Label lbl = (Label)gvdetails.Rows[e.NewEditIndex].Cells[0].FindControl("lblID");
////string id = lbl.Text.Trim();
////int EID = int.Parse(id);
//// Response.Redirect("Admin.aspx?EditId=" + id + "");
//DataRow[] dr = null;
//dr = dtDefault.Select("ID = '" + id + "'");
//txtquestion.Text = dr[0]["question"].ToString();
//txtoption.Text = dr[0]["options"].ToString();
//showdata();
}
}
}
My problem occurs here
protected void gvdetails_RowCommand(object sender, GridViewCommandEventArgs e)
{
//private Int64 n;
//for(int i=0;i<=n;i++)
//{
int id = int.Parse(gvdetails.Rows[0].Cells[0].Text);
DataRow[] dr = null;
dr = dtDefault.Select("ID = '" + id + "'");
txtquestion.Text = dr[0]["question"].ToString();
txtoption.Text = dr[0]["options"].ToString();
//}
showdata();
}
Here is my main problem occurs:
protected void gvdetails_RowCommand(object sender, GridViewCommandEventArgs e)
{
//private Int64 n;
//for(int i=0;i<=n;i++)
//{
int id = int.Parse(gvdetails.Rows[0].Cells[0].Text);
DataRow[] dr = null;
dr = dtDefault.Select("ID = '" + id + "'");
txtquestion.Text = dr[0]["question"].ToString();
txtoption.Text = dr[0]["options"].ToString();
//}
showdata();
}
When I click on any row that display only first row data. I want to get each row data by each clicking on respective textbox of grid row.
I have tried with commandfield but when try to add the data of option textbox (txtoption) in listbox with add button, it automatically display update, cancel option in gridview.

Here is a sample code for your reference. Hope this helps.
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName =="edit")
{
int i = Convert.ToInt32(e.CommandArgument);
YourTextBox1.Text = GridView1.Rows[i].Cells[0].Text;
YourTextBox2.Text = GridView1.Rows[i].Cells[1].Text;
}
}

In the gvdetails_RowCommand event, you're always accessing the first row in the GridView.
int id = int.Parse(gvdetails.Rows[0].Cells[0].Text);
See if this works instead (referencing the currently selected row):
int id = int.Parse(gvdetails.SelectedRow.Cells[0].Text);
