It looks very simple, but becoming increasingly frustrating. I am working with a ASP.NET WebForm where I have the following code for ButtonClear
that clears the text that is entered in the TextBoxes
:
protected void ButtonClearAll_Click(object sender, EventArgs e)
{
TextBox1.Text = string.Empty;
TextBox2.Text = string.Empty;
TextBox3.Text = string.Empty;
TextBox4.Text = string.Empty;
}
Code in .aspx
file:
<asp:Button ID="ButtonClearAll" runat="server" Text="Clear" OnClick="ButtonClearAll_Click"/>
Problem: By clicking ButtonClearAll
once, the four TextBoxes
are clearing fine. But on subsequent click, the RequiredFieldValidators
of the 4 TextBoxes
are getting called and are validating the assigned TextBoxes
to print the appropriate error statements next to each TextBox
.
What to do?
By default any button, invoking any post-back, is going to invoke the validation first. You can disable validation for a particular button with the CausesValidation
property:
<asp:Button ID="ButtonClearAll" CausesValidation="false" ... />
