So I have my login and password txtboxes in the master page header, When I click on login button it should hide those boxes and display something else.But everytime I navigate to another content page they get visible again. What it the best solution to keep them hidden while the user is logged in?
I have a control in a content page that I want to find the width and left attributes of the style. I am trying to find this from Javascript code that exists on the Master Page. How do I do that?
In my application(ASP.NET 3.5) I have a User Control(ascx) that I have on a number of pages. Sometimes I need to reference certain label from the page ascx is on.
I am new to server controls. wanted to know what are the methods and events that has to be written or thought about. which is apartt from the ones inherited from composite controls.
I have a special requirement with regards to popping up a MsgBox in ASP.Net. There seems to be various solutions across the Internet using the Javascript confirm box, and passes the response to a hidden control, from which VB.Net can the read and further respond ...but the Javascript code is initialted by a button on the ASP.Net Form. I want to be able to pop-up a MsgBox in the middle of my VB code-behind using the Javascript trick, which passes the result to the hidden control, which can then be read by VB.Net .... the problem is that the page has not refreshed and the hidden control still contains the value from the previous Submit .... I'll attach my code. If anyone can come up with a solution, will you have achieved the impossible!
I recently came across the AsyncFileUpload control in the latest (3.0.40412) release of the ASP.Net Ajax Control Toolkit. There appears to be an issue when using it in a hidden control that is later revealed, such as a tag with

Server-side Code - [Code]....
I have a breakpoint on the UploadedComplete event but it never fires. However, if you take the AsyncFileUpload control out of the , making it visible at initial page render, the control works as expected.
I have a codebehind.vb for a master page from which I'm trying to find a hiddenfield in the content page. I was finding it like this without a hitch...
I used the script where the image array has static images.I want to convert it dynamically by finding my images names from index.aspx.cs files which are stored in hidden fields.
I want to split this hidden filed and assign it to imagearray.how can i do this
var mygallery2=new fadeSlideShow({ wrapperid: "fadeshow2", //ID of blank DIV on page to house Slideshow dimensions: [568, 313], //width/height of gallery in pixels. Should reflect dimensions of largest image imagearray: [ ["images/1.jpg", "", "", ""], ["images/2.jpg", "", "", ""], ["images/3.jpg"], ["images/4.jpg", "", "", ""] //<--no trailing comma after very last image element! ], displaymode: {type:'auto', pause:2500, cycles:0, wraparound:false}, persist: false, //remember last viewed slide and recall within same session? fadeduration: 500, //transition duration (milliseconds) descreveal: "always", togglerid: "fadeshow2toggler" })
I have placed a textbox, dropdownlist and command button in a section of my master page. The textbox, named txtsearch, will be used to input a search string. The dropdownlist, named ddlsearch, will be used to specify in which field to search in the table, either part name or NSN.
Questions:
What VB code do I use to save the value entered into txtsearch as a search string? How do I pass that value to my entitydatasource? How do I tell entitydatasource to search in either the part name or NSN field based on the value of ddlsearch?

I've created a bunch of asp:hiddenfields dynamically at runtime in an asp.net page.
My question is this:
How do I find those hidden fields?
I have an event attached to a control that fires a javascript function, and that's where I am attempting to use JQuery to find the hidden field associated with that control.
I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.
I've got two textboxes running server side and have their visibility turned off. I'm using a couple of ASP.NET controls which require the textboxes to exist. However, I am filling them from the code behind and would not like the user to see this. Can the user turn the visibility on and see the values entered in the text box? I tried using FireBug, and I couldn't seem to select the visibility option in order to edit it. However, I'm quite new to Firebug, so there may be another way? Or does running it server side mean that the client can't ever view the contents of the textbox?
I have a hidden field (hfUnsaved)in my child page . On keypress of my textbox i am setting the value into the hiddenfield using the following javascript function

On button click i am removing the value from hidden field as follows:

PreviousPage.Master.FindControl("[TestHiddenField]") but no .Value attribute and no luck in general.
i am using <input type="hidden" id="hiddenValue" name="hiddenValue" runat="server">
hidden control in my asp.net, and setting it value when page load, and when i clicked on a button then my server side code change hidden control value, and when i tried to access it value after another clicking of button then it showing me
first time value,
so why hidden control does not reset its value, how can i reset the hidden control value?
My Code
Page_Load(){ if(!Page.IspostBack){ hiddenValue.Value ="ABC"; } } ButtoClick1(){ hiddenValue.Value ="BAD"; } ButtoClick2(){ // it give me 'ABC' value, instead of 'BAD' string s = hiddenValue.Value; }
