Web Forms :: Setting Property For List Dynamically
Feb 25, 2011
How to set proprety for List dynamically. I have a WebPage class having properties. strNodeName is one of the property of this class which is the parameters of method. I want to set the string strTitle according to the parameter strNodeName i.e., set
strTitle = _list[i].Title.ToString();
I want Title to be the strNodeName.
Like if strNodeName = Author, then
strTitle = _list[i].Author.ToString();
if strNodeName = CoAuthor, then
strTitle = _list[i].CoAuthor.ToString(); 
Below is my code.

I have a user control in asp.net that i need to dynmically set properties for. The propety and property values are in a dictionary, for example:
Dictionary<string, string> propertyValues; Control c = Page.LoadControl("~/Control.ascx")
I can currently set the properties on the control using reflection, however, with .net 4 and the new dynamic keyword, is there an easier way to do it, for example, something like this:
I need to set a style property of an element to the value returned from a code-behind property. I have done this in the past, but it now seems everything I try fails. I get an error telling me that the literal is not formed correctly.These are some of the arrangements I have tried:
I am using a master page and web content forms in my project. I have a panel on my web content page which opens a popup window using window.open. When opening the popup window, I disable the panel on the web content form.
When I close the popup window, I want the panel to be enabled. I am trying to do this using javascript, but I am not sure how can I set the enable property of the panel to true using javascript.
I'm creating an quiz application which queries the database and extracts the questions and choices. I use dynamically created controls such as a checkbox list and fill the values dynamically. How do I do this? Right now I have these functions:
array_random_init(); this creates a 10 element integer array from 1-20 - extract_question(i): this extracts a question indexed at i in DB, I created the controls and set the appropriate text in this function. - validate_question(i); this is called by button_click and validates the question i according to DB.
I understand I have to recreate the controls in Page_init on postback, but what should it look like? Do I need to add "if IsPostBack" in page_init, or do I create the controls in page_init() and reset their properties in page_load when I use extract_question(i)? Also, I cannot seem to clear the selected boxes on postback, I added page directive "enableviewstate=false" but it doesn't work.
I'm trying to set the ImageUrl property after I've uploaded an image so that I can display the newly uploaded image, but for some reason it's not working.
If I navigate from the record I've just updated and then return back to that same record, the image then displays. It just doesn't display right after I've updated it. Basically what I'm doing is this:
Sub FormView1_OnItemUpdated(Sender As Object, e As FormViewUpdatedEventArgs)
Dim MyImage As Image MyImage = FormView1.FindControl("Image1") MyImage.ImageUrl = "image1.jpg"[code]....
I've left out the path intentionally because I'm pretty certain that the path I'm giving is correct... again, if I navigate away from the record and then return to it, the image displays. In addition, when I view the "Page Source" to view the resulting html, the src property of the image tag is blank . So, it's not a path issue... the issue is that its not setting the src at all which is why the image is not displaying.
I have two login control in the index page of my website,each of two different usertypes. there are two user types brands and creatives.the branded user will log in to brands bin(brandsbin.aspx) the Creative user will sign in to creativebin(creativebin.aspx) i am using forms authentication for signin. so i am confused here to to rediret to default path for each user types. how to set default page for each user types. in the web config file i have added like this
i have a setup.aspx page where in i select the theme with buttons so if i click on a button the theme should reflect in all of my pages of project.so how can i write the code do i need to call it in each page.how can i set the initial page to do so.
I want to set the selectedindex of ddlExceptionNumbers to a Session variable value. I set my debugger just passed the last line of this code segment, and it doesn't change the selectedindex, it's 0. Session["CurrentExceptionID"] has a non-zero positive value.
however everytime i reload the page,backcolor disappears.If i move it out from IsPostBack block ,it works fine but i want to load grid only when the page loads for first time(inside !Page.IsPostBack).
Is tehre anyway to set the HeaderText dynamically on a gridview? I'm trying the below, it kind of works, but the problem is on the initial load nothing shows up, but when I postback then the new text populates: grdvMyTest.HeaderRow.Cells[5].Text = GetTheCalculatedDate();
I've tried that in both Page_Load and grdMyTest_Load, but same thing happens in both. When the page initial loads the column header text is blank, when I click something causing a postback it pops up. I don't have a IsPostBack check around that line, so it should be running regradless. I'm guessing I'm doing it at the wrong event, either too eariler or too late.
Once the template is loaded and cast back to the TabHeader class, it's null. How can I load that control, set the properties, and use it as the template? Or is the only way to go about doing this to create a custom class?
In the datapager, is there any way to set the NextPageText and PreviousPageText properties dynamically so the NextPageText is set to the title of the the next story in the dataset?
I'm currently developing a localized control which works as a wrapper for the default ASP.NET Login control.
This is my .ascx file:
[Code]....
Problem is, I have to set dynamically from CodeBehind the LogoutText attribute. I tried basically two things:
1. Declaring the Asp:LoginStatus normally in the .designers.ascx.cs file and setting the LogouText attribute's value runtime like this:
[Code]....
... but this does not seem to work since the LoginStatus control is declared into a LoginView control.
2. Setting the value using late bounds, but this fails since to retrieve the loginstatus i have to do such thing:
[Code]....
... but this fails too because late bound removes early references, so i cannot logout the user anymore since the runtime finds a duplicated LoginStatus control and cannot understand which is the right one, or at least i guess so.
I tried to check if someone had the same problem in the past and i found a couple of reports stating that i cannot do such thing like setting attributes runtime for nested controls.
Maybe i'm just missing something, but before throwing everything and setting that attribute statically in the .ascx i would like to make sure.
I have created a user custom control, and what I would like to do is to pass it the text value from a label where I can carry out some other processing.
here's my situation - I've created some ActionFilterAttributes that I want to apply to a custom Controller class that my other controllers can inherit from. The problem is, I need to set a property on the attribute from the final inheriting controller. So I have something like this :
I am adding linkbutton dynamically (actually above snippet tells what I am actually doing, in reality TableRow and TableCell are added dynamiccally). My problem is, I am not setting height of linkbuttuon which will added dynamically. I have no idea what text I have to add to linkbutton.
What I want, after all the link buttons are added, iterate through each added lin button, get the height of each linkbutton, store the max height, then re-iterate throgh the link buttons and set the height of each link button to max height.
I have a ReportViewer control and the PDF download function is working fine. However, the table does not fit to the page of the PDF and part of it appear in 2nd page. I want to have that report fits into one single PDF page.
How can we set the page setting property when it compile the PDF file ?
I need to validate a textbox to ensure the submit date is older than Today. I wanted to use a CompareValidator to do that, but unfortunately the following code doesn't work:
