Not sure if I get it right but.. How did you bind the data on the gridview? If its from a query then you could've just added a parameter.

Solution 1

Using the "RowDataBound" of gridview event to achieve this.

C#

private void GridView_RowDataBound(Object sender, GridViewRowEventArgs e)
 {
    if (e.Row.Cells[2].Text == "") // if need to check the text box entries change the condition accordingly
        e.Row.Visible = false;
 }

Hi Try this code..

XML

<form id="form1" runat="server">
   Number 1:<asp:TextBox ID="txt1" runat="server"></asp:TextBox><br />
   Number 2:<asp:TextBox ID="txt2" runat="server"></asp:TextBox><br />
   Number 3:<asp:TextBox ID="txt3" runat="server"></asp:TextBox><br />
   <asp:Button ID="btnSubmit" runat="server" Text="Load Grid"
       onclick="btnSubmit_Click" /><br />
   <asp:GridView ID="gvNumbers" runat="server">
   </asp:GridView>
   </form>

C#

protected void btnSubmit_Click(object sender, EventArgs e)
       {
           List<int> numbersToHide = new List<int>();
           int number1, number2, number3;
           int.TryParse(txt1.Text, out number1);
           int.TryParse(txt2.Text, out number2);
           int.TryParse(txt3.Text, out number3);
           numbersToHide.Add(number1);
           numbersToHide.Add(number2);
           numbersToHide.Add(number3);

          var data =  Enumerable.Range(1, 100).Where(k => !numbersToHide.Contains(k)).ToList();
          gvNumbers.DataSource = data;
          gvNumbers.DataBind();

       }
