Solution 1

Attach a OnClick Event to the Button.
Inside OnClick Event, get the TextBox Text by txtYourTextBoxID.Text.
Update the DataSource of GridView by adding a new Row. If you are using DataTable, create a new DataRow for that DataTable.
Assign the DataTable to GridView DataSource.
Bind the GridView.

First of all, good attempt. Nice work.

Let me explain the issue in your code now.

The following line...

DataTable dt1 = new DataTable();

will always a new DataTable for you and you are assigning this to the GridView everytime Button is clicked, so the previous DataTable is lost. So, you need to update the existing DataSource.
We have to use ViewState or Session to store the existing DataTable. Take a look at the updated code.
It is tested and working fine.

protected void btnsubmit_Click(object sender, EventArgs e)
{
DataTable dt1 = null;

if (ViewState["GridDataTable"] != null)
{
dt1 = (DataTable)ViewState["GridDataTable"];
}
else
{
dt1 = new DataTable();
dt1.Columns.Add("filename");
}

DataRow dtrow = dt1.NewRow();

dtrow["filename"] = uploadFile.FileName.ToString();
dt1.Rows.Add(dtrow);

ViewState["GridDataTable"] = dt1;
grdfiledetails.DataSource = dt1;
grdfiledetails.DataBind();
}
