and the following interface look
I wish to perform validation on the page only when the "add exhibit button" is clicked. so in my code behind, i used an "if(page.isvalid)" to check for page validation when the button is clicked. However any other button i click fires the validation as well... I presume its because every button click tries to load a page and that calls the validator to action. how do i allow work around the validation such that, only the " add exhibit button" triggers the page validation?

You need to set the ValidationGroup property on the button and the validator. That way you can control what validation takes place.
The ValidationGroup property is an arbitrary tag that you can add to your validators and buttons to group them into logical units. So in your case, I would do this:
For your validators that are relevant for the add exhibit action.
<asp:RequiredFieldValidator ID="RequiredFieldValidator4" ValidationGroup="AddExhibit" ...
For your button that triggers your add exhibit.
<asp:Button ID="addExhibitButton" ValidationGroup="AddExhibit"

OnTextChanged does not trigger after required attribute validation

I have an update Panel with some textbox and I'm trying to replace the requiredfieldvalidators by using the required attribute on the textboxes which makes everything much cleaner. Only first textbox has required for testing purposes.

Now the problem is that i Have this textbox txtNumComps that creates some dynamic textboxes for some input and does it OnTextChanged event and is doing it asynch. The problem is that when the validation from the required attribute fires, the OnTextChanged does not trigger, only triggers the 2nd i write something. I don't see what can cause this problem. if someone could help i'd appreciate.

colspan screwing up css asp.net table

I created a table to organize my items on a page. The page is an edit page for a property.
I used colspan to expand rows and put a textbox within rows and set the textbox wdith to 100%, However, the textbox width still only takes the space of 1 column not 3 columns like I expected here is the code
<table align="left" style="width: 100%; float: left" class="FormFormatTable">
<tr>
<td style="width: 10%; height: 60px">Alert Name</td>
<td colspan="3" style=" ">
<asp:TextBox CssClass="inputBoxes" ID="txtBox_alertName" runat="server"></asp:TextBox>

<td colspan="3" style="">
<asp:TextBox CssClass="inputBoxes" ID="txtBox_SubjectTitle3" runat="server"></asp:TextBox>
</td>
</tr>
</table>
css is simple just this
.inputBoxes {
width: 100%;
}
why is this?
a screenshot of my page on my computer

In you HTML
the Alert Name , Receipients ,Subject Title ,Alert Messsage ,Fields to Display in Details TextBoxs take 3 columns .
Notification Window take one columns because you don't set colspan
you must add colspan="3" to your td of notfication
<td colspan="3" style=" ">
<asp:TextBox CssClass="inputBoxes" ID="txtBox_NotificationWindow" runat="server"></asp:TextBox>
</td>

You have an extra quote in the following line (the cell definition that contains your ddl_Severity control).
<td style=" height: 60px"" >
Maybe remove this quote, and see if that fixes it.

Ajax Modal Popup not closing on TextChange event in IE

In my page, I have a text_change event that is fired and it goes to the database, looks up a value, then sets textbox and hidden field. After those fields are set, I display modal popup to validate the values returned. The issue is once the popup is displayed, it takes about 30 seconds before the close button is active. I have narrowed it down to the text_change event because I have several text_change events on the page which show a modal popup for validation and I get the same behavior for all of them. I do not get the same behavior when I trigger the validation summary on the page from a button_click event I am not sure why there is a delay and how to get past this issue.

Textfield clears after calendar control postback

I have 3 text fields on my page and one calendar control. After I fill in the 3 text boxes, then click a date on the calendar control, the bottom textfield clears out, losing its value. The other 2 text boxes have their values available and do not get cleared. The textboxes all have the same properties, but I can't figure out how to keep the value in the third textbox.

a link is shown on hover of linkbutton
javascript:webforms_DoPostbackWithOption:(NewPostBackoption("","false",true,"false"));

Do you have any validation controls inside application , check once by setting the Cause validation = false to link button control .

Some times your system has changed to old time(like one year back) also the link buttons won't redirect

There may be validation controls inside application , check once by setting the Cause validation = false to link button control .
