I'm thinking there has to be an efficient and OO way to do this.
I have several textboxes on a data entry page. When I need to make a new entry, I have to clear the text field before making new entries and this has to be done for quite a number of textboxes and across several pages.
Is there a way to use the FindControl method to locate all textboxes on a page and clear their textfields probably using a loop of some sorts?
I have a Master Page as well as a standard Web Form aspx file. What if I wanted to dynamically modify the complete HTML markup in an aspx file (perhaps based on a conditional statement - perhaps in a specific content place holder), how would I go about doing this? Sorry I'm coming from a PHP background so this is why I'm asking such a simple question.
View 1 RepliesI'm doing some research on security and sitemaps in ASP.net and am unfortunately running short on time. I have not worked too much with ASP.net security so I'm not completely sure if I'm heading in the right direction.
Here is my problem:
I have a public website (i.e. on the internet) that will allow any user to sign up to. The website will be developed using ASP.net webforms. These users may create other users and assign these users different roles.
Different roles have different restrictions and the menu is displayed appropriately. For example, a user acting as an administrator can see all menu options. Whereas a limited user will only see some of these menu items.
There needs to be the ability for users on our end to modify what pages certain roles can access. For example, if Role1 can do task X, we would like to be able at some point modify Role1 to no longer do task X. This would be done using an application built in-house.
User types (roles) are to be saved in the database. User permissions (what pages each type can have access to) are also to be saved saved in the database.
Here is something I am thinking of doing:
Implement the authorization and authentication set up built in to ASP.net using the web.config fileUse Sitemaps to dynamically create menus/breadcrumbs from the database
I believe it is possible to do the second one using custom providers (please correct me if I'm wrong). But I am not entirely sure if it's possible to configure the web.config file dynamically.
I suppose this is really more of a yes/no answer but I would just like to make sure I'm not going in the wrong direction. I will be using VS2008 and .net 3.5 framework.
I m using multiple sitemaps in my website. The providers are defined in web.config file as:
[Code]....
[Code]....
Now I m trying to modify one of my xml file in memory to dynamically populate querystring but when I use
Dim currentNode
As
SiteMapNode =
SiteMap.CurrentNode.Clone(True)
I get Null in my currentNode and I cant point to the node.
Can I modify the properties of a content page control from an event fired from the master page?create a delegate and event on master page wire up the master page in the content page create the event handler (function) on the content page modify for example:
contents of the Text property of a textbox render a control visible (or hidden) etc...
I want to access the raw HTML code that my ASP.NET System.Web.UI.Page is about to render.
How can i do that? Is there a property or method like System.Web.UI.Page.HTML or something like that.
I know I could loop through the Controls List of the page and get access to all the Literal Controls etc, but I was wondering if there's a direct property or method that can return me the raw html, which I can modify just before rendering the page.
I have been trying to find out how I can allow a user to modify/update a page/pages on a web site. I understand there has to be site security with authentication and authorisation but what is there as a user interface for them easily to update a page?
View 4 RepliesWhen I create a new page in my ASP.NET application I have This code automatically generated:
<%@ Page MasterPageFile="~/Site.master" Language="C#" AutoEventWireup="true" CodeBehind="Rh_Acceuil.aspx.cs" Inherits="PAGODE.RESSHUM.Rh_Acceuil" %>
It's really usefull! But the inherits tag is made with project's directories (the file is in de RESSHUM directory) but I prefer to delete this part and have this:
...Inherits="PAGODE.Rh_Acceuil ...
But I have to do that manually each time..

I've a page main.aspx. This page has a button 'Settings'. When it is clicked, I load another aspx page settigns.aspx in a popup. Now in the settings.aspx i allow the users to add controls dynamically. For example the user can create 5 textboxes. When he saves it there, I need to get that controls to main.aspx.
So i need to move all the controls from one page to another page. I'm not able to think of a solution with user controls.
I created a master page and have several aspx page using it. Now I want to change each of the background image of the page that is using the master page. I used dreamweaver to change its background image but I get an error :
Only Content controls are allowed directly in a content page that contains Content control
How could I modify the background image of each of the content page??

I need to send email to client the product information along with how much grid is generated.

How do I add dynamic controls to such code? Also I need to change mail body as per certain conditions.
I am adding controls dynamically in my webpage.
I add them in onload method.
everything is working fine..
But I m a bit confused about how it works..
I have read in so many articles that all controls get their values from viewstate before load event. Then how my dynamically added controls get their values when i am adding them in OnLoad event ie after LoadPostData event.
I am working on a page where user controls are dynamically added to the page and refreshed with a timer in an updatepanel.
Since I already coded dynamic user control loading into the page, I would also like to implement *some* form of dynamic layout method for those controls. I was thinking coordinate values.
I have used Top and Left properties on panels before to achieve this functionality in my windows forms applications but since this is a web application things are different.
I realize I can do the whole "absolute positioning layout model" override in Visual Studio but as far as I know this only benefits me at design time. Is there a way to programatically trigger that behavior?
I looked at the silverlight Canvas and how you can pass offset values in with your controls. Something like that would be great, but this isn't Silverlight, lol. I also considered a web method to return globs of html tags to fill the area between these controls.
This is a page that would be reused over and over from client to client so this is why I would like to get this dynamic layout working. It would save me much effort later on.
So I was told the following would not be possible:
I have a aspx page that has a number of dropdowns. Each dropdown is set with either a class=leftcolumn or class=rightcolumn.
I need to assign an attribute:
propertyID.Attributes["nameOfAttribute"] = "false";
But instead of manually writing out each controlID and setting its attribute with the line above, I had hoped there was a way to go through and set the attribute on each control ID if it had class=leftcolumn.
This is something I know is possible to do through JQuery easily, but I need it on the code behind during load.
I'm working on an ASP.NET project in which the vast majority of the forms are generated dynamically at run time (form definitions are stored in a DB for customizability). Therefore, I have to dynamically create and add my controls to the Page every time OnLoad fires, regardless of IsPostBack. This has been working just fine and .NET takes care of managing ViewState for these controls.
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
RenderDynamicControls()
}
private void RenderDynamicControls(){
//1. call service layer to retrieve form definition
//2. create and add controls to page container
}
I have a new requirement in which if a user clicks on a given button (this button is created at design time) the page should be re-rendered in a slightly different way. So in addition to the code that executes in OnLoad (i.e. RenderDynamicControls()), I have this code:
protected void MyButton_Click(object sender, EventArgs e)
{
RenderDynamicControlsALittleDifferently() [code]
My question is, is this really the only way to accomplish what I'm after? It seems beyond hacky to effectively render the form twice simply to respond to a button click. I gather from my research that this is simply how the page-lifecycle works in ASP.NET: Namely, that OnLoad must fire on every Postback before child events are invoked. Still, it's worthwhile to check with the SO community before having to drink the kool-aid.
On a related note, once I get this feature completed, I'm planning on throwing an UpdatePanel on the page to perform the page updates via Ajax.
i have an array of buttons added to a panel control and need to reset them to their original values, is this possible pragmatically?
protected void Page_Load(object sender, EventArgs e)
{
RenderTable();
}

I am using jquery ajax method to get data from a web method and present data using DOM(similar to that of google search results).B'coz the data returned from the web method is huge I want to paginate the results.For that I need to create buttons corresponding to the page numbers based on the no. of records the web method retrieves from the database.So I have taken a div on the page.In the web method ,as soon as I can find the number of records obtained from the database,I want to create the buttons and add to this div and display 10 records per page.As far as I know, it is not possible to access anything that is placed on the asp.net page from Web method.In that case how do I paginate the results?
View 2 RepliesI am dynamically adding controls to a page with an updatepanel. The controls do trigger a post back but their events do not fire.
For example:
LinkButton link =
new
LinkButton();
link.Height = 45;
link.Width = 250;
link.Font.Underline =
link.Font.Bold =
link.ValidationGroup = "NoValidation";
link.Click += new
EventHandler(EventDoesNotFire);
I have set a break point on the Load_Page and in the EventDoesNotFire method. The Load_Page fires, but it never enters the EverDoesNotFire method.
Here is what I am trying to do.I have a drop down list along with a 'Add' button (which are always visible). There are some other 'Label', 'TextBox', 'Button' in the page (which is not visible on load). Depending on the user selection from the first dropdown (and when click on 'Add' button), I would like to dynamically set some of the Controls visible.
For example (as per below code): When User selects 'Email' ... Label3, TextBox3 and Button3 will be visible. Again when user will click Button3, all controls will be invisible. I was able to Show and Hide those controls as per user selection and button click.
What I would like to do is, rearrange the controls. For example, If user selects 'Email' and click 'Add' button (Button5), It would display 'Label3', 'TextBox3', 'Button3'. Then if user selects 'Name' from the dropdown and click 'Add' button again, it would display 'Label1', 'TextBox1', 'Button1' below the Email controls. As of now it is apperaing on sequence as listed in html (Name controls always come first when visible, then 'Phone', then 'Email'). I would like to display the controls as sequesnce as user selects.
And next is when we will click the Button3 (which will hide the email controls), All other controls below email controls should rearrange and come up.
I hope I was able to explain what I want to do. There might be a very easy way (may be there is already a toolkit I don't know about).
