Web Forms :: Validate TextBox Before Submit Button
Oct 28, 2010
I have a textbox that I am "custom" validating to lookup in a table to see if the name exists. When I test it out, if it finds a duplicate, the validation results in an error message as I would expect. First is this only works if I add autopostback to my textbox and that I click elsewhere on the page. The other issue is that after I type a string in my textbox, I want it to validate such that if it returns an error, I don't want to submit the form until the validation is good.
How would I programatically set this up?

I created a web part called 'staff phone search'. There are two controls 'Button' and 'Textbox' in it. The web part is inherited from Webcontrols webpart class not from sharepoint web part.My problem is that if I fill the search keyword text box and click the button, the text box and the button disappear. However the webpart displays result properly. Subsequently I am not able to search again because the web part never shows the controls again. How can I keep the controls after the webpart is submitted?
My code can be found below.
public class WebPart1 : System.Web.UI.WebControls.WebParts.WebPart
{
TextBox _myTextBox;

This usercontrol doesnot have any buttons.
The user control is included inside a page. The page has other textboxes and a submit button.
How do i ensure the the forms in usercontrol is valid when i click the submit button outside on the page?

I have a page with multiple textboxes and each has a button associated with it. This works as a search 'hub', I suppose, where the user can search by ID, name etc. When entering a search term for e.g. name however, pressing enter 'clicks' the very first button on the page (ID search), causing an error if the associated textbox is empty (which it would be if someone meant to search by name). I have attempted to rectify this using JQuery, and have written the following:
$('input:text').click(function (e) {
e.preventDefault();
$(this).next('input:button').focus();
});
I'm simply using the click event so that I can monitor where focus is redirected, but eventually I would use .keypress. However, nothing happens upon clicking a textbox and I can't see for the life of me what is wrong with the JQuery. To elaborate on the problem, the .NET code used looks similar to the following throughout the page.
<tr>
<td style="width:100">Company ID</td>
<td style="margin-left:3px;">
<asp:TextBox ID="...TextBox" runat="server" Width="230px"></asp:TextBox>
</td>
<td>
<asp:Button CssClass="Button" ID="...NameSearch" Text="Search" runat="server" /></td></tr>
This is generating this (view source):
<td><input name="...TextBox" id="...TextBox" style="width: 230px;" type="text"/></td>
<td><input name="...NameSearch" class="Button" id="...NameSearch" onclick="javascript:__doPostBack('...NameSearch','')" type="button" value="Search"/></td>

I have a modalpopupextender with popupcontrolid set to a panel. I have a name textbox, label, submit button in the panel. When the submit button is clicked the name is validated using a function connecting to the DB. If It already exists the label should show "Already Exists". I have set the label text in the buttonclick event handler but the label is no set. The popup just closes. I want the label to be set and make the popup remain unclosed. How to achieve this functionality ?
<asp:ModalPopupExtender ID="ModalPopupExtender" runat="server"
TargetControlID="NewUserButton"
PopupControlID="NewUserPanel"
BackgroundCssClass="modalBackground"
OnOkScript="onOk()"
CancelControlID="CancelBtnNewUser"....

I have a form that looks like this :
[ enterdata: [______] ; more data: [_____] ; (SUBMITBUTTON) ]
[ Filter: [_______] ; (SUBMITBUTTON) ]
The top half has validators. I want to be able to type into the Filter textbox and press enter to fire it's submit button - but when I press enter, it validates the top half of the form also. I have all the controls in the top half on one ValidationGroup, and all of the controls on the bottom half in another.

Possible to use a link control to validate and submit a form? What would be the code to tie the click event of the link control to the submission functions? (I prefer link buttons much more than input buttons for styling across browsers.)

I have a databound Gridview (with a LINQ datasource). The gridview displays questions from the SQL DB to the user. I've inserted a radio button list into the gridview with 3 horizontal radio buttons with fixed values of 1,2,3 for the user to select. I have a question ID, a tempuserID, and AnswerValue columns set up in the database. It all works nicely.
After the user selects radio buttons, I would like for them to push a button to submit the QuestionID, the associated Radio Button Value (AnswerValue) and their tempUserID into the DB. How do I do this? I'm not sure what to do next and what VB/LINQ code to put in the code behind file in the button click event handler. I'm also not sure on what to use for the tempUserID, can I use the sessionID? I'm using VB and here's my code:

I know that I can htmlencode and decode server side with ASP.Net, but i've run into an issue if I want to work with some of my forms that should allow html tags when working out side of my companies network. The issue is with my companies firewall tests for cross site scripting attacks. So, now I need to encode/decode my text on the client side it would seem. What does the rest of the world use and/or do to overcome issues like this?
