MVC :: Adding Image To Asp:Content Control At Runtime?
Jun 7, 2010
I am converting a web forms site to MVC and there are a lot of pages all with an individual screenshot image on. Rather than have a separate page for each screenshot image, I though a better way to do this would be to have one page, and to pass the image details into a Controller method, and then set the src value of the <img> in my code. Does anybody know how to do this, and even if it is a good idea to be making reference to UI elements in my Controller code?
I am showing data from different databases in a web part. Would it be possible to dynamically add and remove that data including the layout that that <DIV> has and would I go about in doing this?
I'd like to add a control A (that exists on a page) to a Footer user control's panel. If I create the control A dynamically and add it, I don't have issues. But I would like to avoid adding this dynamically.So, I defined control A in the aspx page and in the code behind, I got reference to the footer's panel and did a Controls.Add() It works fine, but postbacks from this control has strange behavior (could be due to viewstate?) as it doesn't execute some code that is on the page with a !IsPostback condition
I have a hyper link control and I set the NavigateURL and the ImageURL property at runtime. I also need to set the class of the image tag that it generates but I cannot figure out how I can do that. The solution mentioned here [URL] does not work because the image url is hard coded.
I have have two radio button lists that need to be mutally exculisve, i.e when one is clicked the other one neesd to be cleared, my further problem is beause they are in a formview I had to add handlers to clear all the controls in the other list when the one is clicked and vice versa. here is the code below Now the code works but one of the testers found that if you click back and forth around twenty times you get the above java error:
Exception message: Maximum request length exceeded
my though here is the handler is being added to many times ? but even if I remove the handler after the process is complete I still get the same error.
to duplicate an already existing <div> with its existing controls multiple times on one form. I have a situation where I have a group of controls contained in one <div>, but the user might need to add more information in the same format so I would like to just have them click a button to add another component and the same set of controls will be duplicated below it.
In my Page_Load() event, I'm calling a Sub (in a module UserMenu.vb) that reads an XML file which has the user menu entries. The final menu should be an <ul> with several <li>, some of them with anidated <ul> within. As I understand, I may use a asp:Panel in my page to position a container for this elements I read and in this sub I try to add them using new BulletedList and new ListElement BList.Items.Add(LItem)), but when I get to Panel.Controls.Add(BList) it throws an error that says BList should be inserted in a Form. Why? Aren't they just <ul> and <li>? What other alternative I have to create <ul> and <li> in a specific part of my page?
i have an image and an imagebutton, they are inside a listview and get their imageurl from databinding, i would like to know, if maybe the databinding value is empty, instead of showing a big red x, is there anyway to maybe make it link to a default image when the value is empty instead?
I am creating a web application that displays URL to users in a GridView. The application has a code behind that will be doing the processing before it can return me a URL. This is done in a loop. So it looks something like :
[Code]....
What I wanted is to make the Gridview always update the rows everytime an item in the loop is done instead of waiting for the loop to finish.
For now, the application will only display the whole table until the code/loop finishes. I'm very much aware that this will happen because the web page is static in the first place. Does anybody know how to do this?
I have tried of using iframes(I thought of reloading the frame so the whole page wont reload again and a new GridView table would appear because of the code in Page_Load event because I tried placing the data in a separate static class and the GridView.aspx page will just retrieve the values upon every reload)
and I'm not sure how to implement AJAX/Javascript with this. Is Animation involved in this kind of situations?
i am developing a small website where on one page user selects an image [selected image id is passed to another page] and on the next page logo is selected which is passed onto next page [selected logoid is passed]..now in third web-page actual watermark happens where user can select the postion where watermarking is needed to do ...
the problem is the third webpage...here i know the imageid and logoid..but dont know how to select imagecontent and logocontent using both the ids....because as per my knowledge i think using sql-query i can select columns of only one table...
