I have a few template fields (text boxes) in Grid View. After filling in data in the fields, when I click 'Submit' Button, the data disappears. Can any one kindly help me to resolve this?

Thanks

We'll need to see your code.

Here is the code:
protected void btnSubmit_Click(object sender, EventArgs e)
{
try
{

if (GridView1.Rows.Count != 0)
{
for (int i = 0; i < GridView1.Rows.Count; i++)
{
for (int x = 0; x < GridView1.Columns.Count; x ++)
{
if (x == 2)
{
TextBox tb1 = (TextBox)GridView1.Rows[i].FindControl("txtIntDt");
txtdt = tb1.Text.ToString();

}
else if (x == 4)
{
TextBox tb2 = (TextBox)GridView1.Rows[i].FindControl("txtITDt");
txtdt = tb2.Text.ToString();

}
else if (x == 6)
{
TextBox tb3 = (TextBox)GridView1.Rows[i].FindControl("txtBimsDt");
txtdt = tb3.Text.ToString();

}
else if (x == 8)
{
TextBox tb4 = (TextBox)GridView1.Rows[i].FindControl("txtQMDt");
txtdt = tb4.Text.ToString()
;
}
else if (x == 10)
{
TextBox tb5 = (TextBox)GridView1.Rows[i].FindControl("txt5Dt");
txtdt = tb5.Text.ToString();

}
else if (x == 12)
{
TextBox tb6 = (TextBox)GridView1.Rows[i].FindControl("txt6Dt");
txtdt = tb6.Text.ToString();

}
else if (x == 14)
{
TextBox tb7 = (TextBox)GridView1.Rows[i].FindControl("txtTTDt");
txtdt = tb7.Text.ToString();

}

if (txtdt != "")
{

----here i am updating the tables, but not happening because the value is always null---
}

}

}

Solution 1

Check your Page_Load method: I'm betting you clear the fields there.
Page_Load is called fro all page activities, including the postbacks caused by button clicks, so unless you check for a post back they will be cleared before the click event handler gets to run.

C#

protected void Page_Load(object sender, EventArgs e)
    {
    if (!IsPostBack)
        {
        // Handle the initial page setup.

on page load event I did manage that. As suggested I am binding data on every event, it works. Thanks.
