I have some controls, textboxes, etc with RequiredFieldValidators attached. When they are visible from page load, they work fine.
However, I want to start them as invisible, and on a button click, make them visible. The onclick event sets the controls to visible, but the Validators won't fire.
I am trying to use a custom image for my textbox controls. In Photoshop I used an inner bevel. The only way I can find is to use the CssClass property and then use background-image in css. Problem is the text appears a few pixels to the top right in the box and is not very readable with the shadow. I need to center the text in the textbox. How can I do that?
View 3 RepliesI have some tables in my asp.net mvc application for layout purposes. Even though I usually use divs for most things, in some cases tables make most sense because they already have exactly the layout I'm after in these cases.
The only problem is, as far as I know the borders are supposed to be invisible unless you specify a width and style for the borders. But they aren't... They are rather vague, yes, but there are still light blue borders around each cell. What is that and how do I get rid of them? (Funny thing is I don't remember having seen this before when I used tables, which was a while ago).
I also tried specifically setting the border to 0px on both table and td, but that didn't work either...
I am developing one custom control. I dont want default web control property should be in my custom control.For example.[Code]....

View 3 RepliesI have a usercontrol which has a combobox inside it.
This UserControl is the inside an asp panel - and when the panel is visible, the dropdownlist within the control binds to its datasource and behaves itself.
When the panel visibility is set to false, the dropdownlist within the usercontrol is empty.
I have a User Control which consists of a TextBox with a few extras, but for purposes of this example just assuming it's a plain TextBox will be sufficient. I am calling this User Control from a Web Form and would like to be able to use a RequiredFieldValidator that basically would function the same as if I used it on a TextBox on the web form. How do I configure my User Control to handle this?
EDIT:
DatePicker.ascx
<asp:TextBox runat="server" ID="myControlTB">
DatePicker.ascx.cs
[ValidationProperty("Text")]
public partial class DatePicker : System.Web.UI.UserControl

I have a user control (form) inside a user control (grid) with a Validator in the form. A snippet from the code is below
<asp:tablerow>
<asp:tablecell HorizontalAlign="center" columnspan="2" >
<asp:ValidationSummary runat="server" id="ValidationSummary1" />
[code]...
This code is identical to code in another user control where the parent is not a user control and that page works fine, but on this page the Validator doesn't fire and the Foo_ItemCommand method fires instead. I tried searching Google and StackOverFlow but haven't been able to find anything that helps.
I bound the gridview having some fields(ID, StudName, City) and Display Button. When I click on the Disply button I approve the student and updation will happen.
Bu what happen the column ID is not in the sequence. Sometime it displays 1,2,3,4,5,6 ... next time it will display 7,8,9,10,11.... I want a sequence for the column ID. For that I used :
<%# Container.DataItemIndex+1 %>
and it is working fine.. But again I realize that these numbers are generating at runtime and i can't refer to that student. Also I don't want to display ID column on the grid view but I want to use on runtime generated column. [ i am using RowCommand for ID column ] How it is possible?
I am using VS2008. When I tried to implement AJAX to my application, I couldn't get the smart tag for the Required Field Validator in the webform. I need it to implement 'ValidatorCalloutExtender' (AJAX) control in my application.
View 1 RepliesI have a Gridview and I allow fullscreen editing. I have some RequiredFieldValidators in my Gridview and this works fine. But if the user clicks on a dropdownlist in the Gridview and chooses "Rejected", I want to turn off validation. But I am not sure how to do this. Here is my code in the SelectedIndexChanged event for the ddl:
Protected Sub ddlPOACKCodes_SelectedIndexChanged(ByVal
sender As
Object,
ByVal e
As System.EventArgs)
[Code].....
But I get an error on this line: rfv = gvPODetail.SelectedRow.FindControl("rfv11"). the error is:
Object reference not set to an instance of an object.
I am using the async file upload control to upload to a image file. I want the user to upload only jpg files. And for that I am checking the uploadedfile content type in server side, after the upload complets. I wanna check this, before upload starts. There is one javascript method
function startUpload(sender, args){}
but how to access the content type of the file selected by user.
As the title says, I wan't to run some code when the application starts. I have a vague idea that there is probably an event in the application life cycle but I am a bit unsure and could do with pointing in the right direction. So how do I make code run when the application starts?

All of a sudden my debugging is taking forever to start on localhost (several minutes). It also takes a long time to return to the vwd after I stop debugging.
I haven't done anything that I can think of that would change anything (it has worked in the past, although the slow stop may have been there for some time.
The only thing I did was to add another user to the membership db.
I think it's a problem with starting the localhost development server.
I'm not sure if the topic describes my problem very well but I am creating some HTML elements (textboxes) on the fly with jQuery and I never know how many I will create (it loops through a database). I then want to get all the elements in the code behind and perform some actions (insert them into another database).
I know I can use
string n = String.Format("{0}", Request.Form["hiddenField0"]).ToString();
To get the first textbox but what if Idon't know how many textboxes I have created and want them all? Their name starts with hiddenField plus an incrementing number.
Is there a way to loop through all elements that has a name that starts with a certain string?
I created a Virtual Application in IIS 7 to host my app so I could test it on other machines on the local network, since the development web server will not respond to requests from machines other than the local machine. I had to allow IIS to login as me to get into My Documents, and enabled ASP.NET impersonation through the IIS. That worked fine, but...
Now the ASP.NET Development Webserver won't serve anything at all. I hit debug in VS2008, the dev webserver starts up seemingly fine, but then the IDE launches Chrome and the browser just sits there twiddling its thumbs. It never fails, but never loads. Nothing.
There are no errors from ASP.NET Development Webserver or Visual Studio or Chrome that I can find. I even looked in the Event Log. Nothing.
What's the regular expression to check if a string starts with "mailto" or "ftp" or "joe" or...
Now I am using C# and code like this in a big if with many ors:
String.StartsWith("mailto:")
String.StartsWith("ftp")
It looks like a regex would be better for this. Or is there a C# way I am missing here?
