Submit form after clearing field

Posted on 2008-10-24
Last Modified: 2012-05-05

I have a form that has a search field on it.  When a person clicks search, the form is submitted and I am using the FormParameter in a Gridview to filter the records based on their entry into the field.  The default parameter for the FormParameter is %, so if the field is left blank and the form is submitted, all records are shown.

I have a second button called View All and when the user clicks on that, I want the field value to clear out then submit the form.

It is not working.  The first time I click the view all button, the form is sumbitted and the field is cleared out, but the gridview is still filtered.  The second time I click the view all button, I get the results I want, the form is sumbitted with the blank textbox and all records are shown.

How can I do this with one click of the view all button?  I thought maybe I could have javascript clear out the field, then submit, but I couldn't get that to work....

Sorry it took so long for me to test this.  I get the same behavior with this, I have to click the view all button twice...

Never mind, got it working.  I ended up using the following:

    public void Page_Load(Object sender, EventArgs E)
            clearButton.Attributes.Add("onClick", "Empty ();");

function Empty()
document.form1.searchTextBox.value = "";

Thanks for your help,
