I have a text box in which I want only digits (either decimal or whole numbers). I have applied Required Field Validator and Regular Expression Validator on it.I have an Image Button, by clicking on which, I want this validation to be performed. But when I build the code, and clicks on Image Button, these validators do not work and I am redirected to the server side method of Image Button and after completing the execution of server side method, control comes to these validators and client side validation executes.I am fed up by finding solutions on Google and unable to find any solution.Please tell me of anyone of you know the solution that why server side code is running first and client side validation is executing after server side code execution.
I am having an issue with a user control that contains a dropdown and a validator. I created a property for the "CausesValidation" property on the dropdown and set it to false. And yet the dropdown is still triggering the validator. I am having issues with this elsewhere as well including on my ModalPopup.
I have a couple of validators on a modal popup. They trigger properly for the controls on the modal. On the main page I have an updatepanel and can commit a save. When I commit a save and go back to the modal popup the validator error messages for both validators appear. Why is this happening and how can I stop it?
I have a web page that I am trying to use modal popup extender with aLink button as trigger (Code Below). When I execute the code and click on the link button (TargetId) the parameter for graying out the page below the popup works but I do not see the ModalPopup panel
I'm building a button in my code behind file and want to bind the click function to an existing click function of a different button. How do I handle this? I was hoping for something simple like:
Button b = new Button(); b.onClick = otherClickEvent();
but apparently that's not doable. Am I missing something here. I'm aware of OnClientClick, but that only deals with the JS side of things apparently.
I have a ListBox that contains userNames which is inputted by a user during run time. This number of items in the ListBox is dependent on the user's input. These userNames will then be used in a Lambda expression like this:
var vHandleResult = vHandleResult.Where(a => a.UserName.Contains("userName"));
This works fine when there is only 1 user in the ListBox but doesn't produce the correct results when there are multiple items in the listBox. I tried manually creating the expression which should be written as this:
I tried forming the "a.UserName.Contains("userName") expression as a string which is dependent on the number of the items (using foreach) and then just plug in the resulting string in the expression but it seems that it doesnt accept string as an expression.
I have a weird thing happening. I have two identical databases installed on one virtual machine but under two different instances of SQLServer. For some reason, periodically when saving from one it will save to the other instead. Using debug, I have verified that the connection string is correct and when the item saves, it still saves to the wrong database.I use session variable, and am of the belief that it might have something to do with it...and t hat when I go from one to the other it is still getting the connection string form the other for some reason.To make sure that it isn't a problem, I make sure that I completely close out one database before opening the other in a new IE window.I assume that when I completely close out an internet explorer window that it abandons all session states. Is that true?
I created a GridView in code with a DataTable as its data source which worked fine. I have now moved the GridView creation into a .ascx file to make it easier to format.
For some reason this has started triggering the HttpParseException: Databinding expressions are only supported on objects that have a DataBinding event. System.Web.UI.WebControls.HyperLinkField Original code: // Set up columns for datagrid var boundField = new HyperLinkField [code]...
I have confronted a problem of using MaskedEditExtender when try to restrict user to input a number mask with mask. User input of course has no problem. The problem is when the system get the value from database or somewhere (doing assignation), the textbox show the wrong value with the following mask setting: I am writing to contribute and share my solution: example:
textbox1: 1.1 (user input) by using the following mask: <asp:MaskedEditExtender ID="meeXML" runat="server" TargetControlID="textbox1" Mask="999.99" MessageValidatorTip="true" OnFocusCssClass="MaskedEditFocus" OnInvalidCssClass="MaskedEditError" MaskType="Number" InputDirection="RightToLeft" AcceptNegative="Left" ClearMaskOnLostFocus="True" ErrorTooltipEnabled="True"/> When the system get back the data, textbox1 will show: textbox1: 0.11 <- that is not the actual what I want: ========================================== the solution: ========================================== <asp:MaskedEditExtender ID="meeXML" runat="server" TargetControlID="textbox1" Mask="NNNNNNNNNNNN" MessageValidatorTip="true" OnFocusCssClass="MaskedEditFocus" OnInvalidCssClass="MaskedEditError" MaskType="Number" InputDirection="RightToLeft" AcceptNegative="Left" ClearMaskOnLostFocus="True" Filtered="." ErrorTooltipEnabled="True"/>
I have a page where I am using 2 update panels. The first update panel contains a form that has some validation tied to it. The second on has a simple form, but no validation. When I go to use the form in the second panel, the postback is halted by the validators in the first panel. Everything works as it should when I remove the validators.
Server Click event is not being triggered when I click on the "LookupButton". The weird part is that this code works on our Dev server, but not QA. If I get rid of "LookupValidationGroup", from the Lookup Button ValidationGroup property, the page does postback, but then my validators do not work. I could explicitly do the validation on the Server Side, but dont think I should need to.
No errors are being displayed. I also reinstalled .net 3.5 using aspnet_regiis -i command.
I am trying to update a database table(sql 2000 server) using a sqlCommand object. I have created a basic form and added asp.net validators to the text boxes.
I have also included an extra text box with id "UpdateStuID" which accepts a particular ID for retrieving values from the database into the other textboxes. It happens on click event of button "retrieveDeails" .
After retrieving details I have another button called "UpdateDetails" for updating the database values.
Now the problem I am facing here is that, The VALIDATORS fire up when I click on "retrieveDetails" after entering a valid ID. I guess this is because the validators fire up every time we connect to the database.
But here I am only retrieving values and later on updating them.
But because the validators fire up immediately after click on "retrieveDetails" no values are retrieved in the textboxes.
When I remove the validators everything works as expected. But I do need them when I click on "updateDetails" button.
So I want to know whether there is a way so that I can make the validators fire up only on the click of "updateDetails" button.
BTW I am using Required and RegularExpression validators.
I have a webform where I have validators and submit buttons.WhatI am looking for one of my button is1. When its clicked, if all the validators are satisfied, 2. If all the validators are ok, It should disable the button for postback so that user cannot click it again during its process ( means during postback )3. it should enable back after postback if possible otherwise I can do it from code behind at the end of my process,
I've had this problem for a while now, it seems to come and go (sometimes it happens, sometimes it doesn't) and I can't really figure out what's wrong.Basically my aspx code will sometimes format automatically, except not in the way I want it to. I always structure html and xml-like code as such:
This way I can quickly see which tags belong to which, and I think this is the usual way html is formatted, right? Anyway, suppose that I have this code in my aspx code window (don't mind that it's not aspx code, that's not the point), then sometimes VS will automatically format it to this:
Basically it seems to put all closing tags on the last line, leaving me sometimes (with many nested tags) with an extremely long line at the end, making it completely impossible to see the structure of my code. Here is an actual example. This is how I wrote my code:
I am working on an mvc application. Two tables each have their individual submit button. Table1 has default submit on enter key. How do I change the submit button based on textbox focus?
I have a text box and many buttons. When user is in some text box and presses the "enter" key then specific button click event is raised. I read on the internet that there are some problems with the "enter" key and I tried few solutions but still it always enters that button event (that button is the first button in the page).
I tried creating a button which does nothing and writing this in the page_load:
Button1 works fine, it causes the validator to work. Button2 works fine, it doesn't cause the validator to work because it's CauseValidation=false But, Button3 in Repeater1 items doesn't work as I want, it still fire the validation of the validator.
I am creating a page which contains an updatepanel.
In this update panel there is a grid view in which there is a button. on click of this button i m showing a dialog box which takes some inputs and submits data.
However this all is working very fine untill and unless I use some requiredfieldvalidators to validate the input.
when i use validators, these validators works very fine bt the submit button on popup does not work.
I had tried to use validation group but it still does not work at all.
I am trying to write some code where it sets the imageUrl of an ASP Image from the codebehind (on a timer), but it does not change it on my screen (its changing in debug view). I assume this is because I need to postback everytime I change the image. Problem is, I cant trigger the postback from CodeBehind so that it will change. How do I do that?

I am so used to win32 forms -- Just started again with ASP websites.
