Enable/Disable Required field validator from cs page?

rated 0 times [ 8] [ 6] / answers: 1 / hits: 79567 / 11 Years ago, fri, april 5, 2013, 12:00:00

I have two TextBox and two Buttons in my page.

One is hidden and the other one is displayed.

When I click the Button1, it will save data of the two TextBox and will validate each TextBox by the RequiredFieldValidator.

Then when I click Button2, it will just hide itself (Button2) and will show the hidden TextBox.

Both TextBox has RequiredFieldValidator validating against Button1's Event click.

Now my issue is when I simply enter text to the 1st TextBox and click save, the button click is validating the required field for hidden field. I just want to validate the 2 textbox when it is showing.

How can I avoid this?

Well you can simple use the Enabled=false property of RequiredFieldValidator.

Your markup would look something like this based on your Question.

<asp:TextBox runat=server ID=tb1></asp:TextBox>

<asp:RequiredFieldValidator runat=server ID=rfv1 ControlToValidate=tb1 ErrorMessage=* ValidationGroup=gvSave>

</asp:RequiredFieldValidator>



<asp:TextBox runat=server ID=tb2 Visible=false></asp:TextBox>

<asp:RequiredFieldValidator runat=server ID=rfv2 ControlToValidate=tb2 ErrorMessage=* Enabled=false ValidationGroup=gvSave>

</asp:RequiredFieldValidator>



<asp:Button runat=server ID=btn1 Text=Save onclick=btn1_Click ValidationGroup=gvSave/>

<asp:Button runat=server ID=btn2 Text=Show onclick=btn2_Click />

And your codebehind like this:

protected void btn2_Click(object sender, EventArgs e)

{

    tb2.Visible = true;

    rfv2.Enabled = true; // Enables the second requiredfieldvalidator

}



protected void btn1_Click(object sender, EventArgs e)

{

  // your Saving code here

}
