0	Hi, Use Required field validator for this instead of going for c# or JS <EditItemTemplate> <asp:TextBox ID="txtDate" Text='<%#Bind("Date") %>' runat="server"></asp:TextBox> <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="txtDate" ErrorMessage="Please enter EventDate"></asp:RequiredFieldValidator> </EditItemTemplate> Control to validate is Id of the respected textbox to which you want to validate.

Hi,

Use Required field validator for this instead of going for c# or JS

  <EditItemTemplate>

<asp:TextBox ID="txtDate" Text='<%#Bind("Date") %>' runat="server"></asp:TextBox>

        <asp:RequiredFieldValidator ID="RequiredFieldValidator2"   runat="server" ControlToValidate="txtDate" ErrorMessage="Please enter EventDate">*</asp:RequiredFieldValidator>

  </EditItemTemplate>

Control to validate is Id of the respected textbox to which you want to validate.

Thanks & Regards

hi sugi
here i am providing the code to validate two text-boxes with a condition that two must be filled you just use this code for the text-box of grid view template
In Aspx

<div>

    <asp:TextBox ID="TextBox1" runat="server" ></asp:TextBox>

     <asp:TextBox ID="TextBox2" runat="server" ></asp:TextBox>

     <asp:Button ID="button1" runat="server" OnClick="validate" />

    </div>

In code behind

 protected void validate(object sender, EventArgs e)

    {

        string name1 = TextBox1.Text;

        string name2 = TextBox2.Text;

        if (((string.IsNullOrEmpty(name1)) && (!string.IsNullOrEmpty(name2))) || ((!string.IsNullOrEmpty(name1)) && (string.IsNullOrEmpty(name2))))

        {

            Response.Write("Please fill the two boxes");

        }

        else

        {

            Response.Write("Thank You");

        }

    }

Thanks and Regards
