C# - How To Dynamically Retrieve All The Possible Attributes (variable Attributes) Values Of One Of The Xml Node
Aug 10, 2010I am using the following XML structure
<SERVERS>
<SERVER NAME="A1" ID="1"></SERVER>
<SERVER NAME="A2"></SERVER>
<SERVER NAME="A3" ID="3" Parent="XYZ"></SERVER>
<SERVER NAME="A4" ID="4"></SERVER>
<SERVER NAME="A5" Parent="abc" value="10"></SERVER>
<SERVER NAME="A6"></SERVER>
</SERVERS>
I am accessing this xml file by using LINQ to XML in asp.net by using C#. I am able to access all the attributes of an XML node by explicitly specifying the name of the attribute. I want to write query on this xml file which reads all the attribute values of the xml node (In our example the node is SERVER) dynamically means I want to write the query which can read the read the value of the attribute Name & ID from first node, only name from second row, Name, ID & Parent from the third row , Name & ID from the fourth row, Name, Parent & Value from the fifth row & only Name from the sixth row without modifying the existing code every time. Once I add one of the attribute ( for example if I add the attribute ID in the sixth row ) in the above xml file then I dont need to modify my LINQ to XML query. My query should dynamically fetch the total number of attributes & display their values. Is their any way to do this ?
C# - Dynamically Update Attributes Of ASP Controls Dynamically?
Sep 2, 2010In my aspx page, I have a number of drop down controls. I would like to update an attribute on each of the controls with "class=leftColumn" with the following line: 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 very easy with JQuery, BUT I need to do it with the code behind (C#) I was told this is not possible (i.e. to acquire a list of all the controls and then iterate through the list and give it the attribute or any other way. That manually setting each control like the above example is the only way in ASP.NET.
Removing Validation Attributes Conditionally?

{
var id = e.checked;
if (id)
{
$('.dd').attr('disabled', true);
}
else
{

}

dd is the class assigned to all the controls that i want to be disabled. what i have to do to remove the validation properties
Dynamically Access User Control Attributes?
Mar 18, 2010Im trying to create a "user control menu" where links to a page's usercontrols are placed at the top of the page. This will allow me to put several usercontrols on a page and allow the user to jump to that section of the page without scrolling so much. In order to do this, I put each usercontrol in a folder (usercontrols) and gave each control a Description property (<%@ Control Language="C#" Description = "Vehicles" .... %>).
My question is how can I access this description dynamically? I want to use this description as the link in my menu. So far, I have a foreach on my page that looks in the ControlCollection for a control that is of the ASP.usercontrols type. If it is I would assume that I could access its attributes and grab that description property. How can I do this? (Im also open to a better way to achieve my "user control menu", but maybe thats another question.) Should I use ((System.Web.UI.UserControl)mydynamiccontrol).Attributes.Keys?
Web Forms :: Maintaining Attributes Of Dynamically Created Controls?
Mar 1, 2011 have some code which dynamically generates a number of drop down lists to provide the user with different options. The items in these drop downlists contain a value which is a unique id for that particular combination of options and a text component which just plain text but not neccessarily unique. I then have assigned a handler to these dropdownlists which is called on selected index changed to perform the relevant actions based on what options are selected. The problem is to make the system perform the correct action I need the unique ID from selectedValue of the drop down box but when it posts back it appears the selectedValue has been replaced to match the text of the item.
Dim dynDdl = New DropDownList()
dynDdl.ID = "ddlOpts" & i
dynDdl.AutoPostBack = True
AddHandler dynDdl.SelectedIndexChanged, AddressOf dynDdl_selectedIndexChanged

Web Forms :: Dynamically Change Attributes - Add A Class To The Div If The Page Above Is Clicked Too
Feb 5, 2010I have a menu generated by my cms:

<div runat='server' id='menu2'>
<a href='default.aspx?subpageid=8'>rrr</a>

I would like to change the link that has been clicked, to class="active". I would like to add a class to the div if the page above is clicked too.
If (Len(Request.QueryString("pageid")) <> 0 and Request.QueryString("pageid") = 4) Then
menu & Request.QueryString("pageid") & .Attributes.Add("class", "active")
link & Request.QueryString("pageid") & .Attributes.Add("class", "activelink")
end if

MVC :: Dynamically Fill An Anchor Tag At Runtime?
Mar 31, 2011I want to create a mailto anchor tag at runtime. Is this possible? I've tried this:
[Code]....
Neither of these worked. I tried adding the "mailto:" in front of the {0}, but this just became part of the perceived URL. I read a post online about using data attributes to add the value as a property of a class, but I can't do that, as I'm stuck using .NET 3.5 for this project. I honestly didn't think this was going to be such a big deal. I just want to populate the email address of the anchor tag with a variable value.

AJAX :: Dynamically Creating Accordions At Runtime
Jan 21, 2011Newbie in using AJAX . Programming in C# and using SQL as a database. Here is my scenario. User selects a project and I want to display the subprojects related to that project. Here is the query I use to retrieve subprojects.
"SELECT SubProjectName,StartDate,Description FROM SubProject WHERE ProjectName'"+ddlProjectName.text+"';
Currently I store the results of the query in a Dataset. I want to get the SubProjectName in the Header of the Accordion and StartDate and Description values to the text box for each accordion. ( This is what I need to do in each accordian for each subproject)
<asp:AccordionPane ID="AccordionPane2" runat="server">
<Header>
<a href="" onclick="return false;" class="accordionLink">SubProject 1</a>
</Header>
<Content>
<table width="100%" cellpadding="0" cellspacing="0">
<tr>
<td class="td_left" colspan="2">
<asp:Label ID="Label1" runat="server" Text="Start Date"></asp:Label>
</td>
<td class="td_left" colspan="2">
<asp:TextBox ID="StartDate" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td class="td_left" colspan="2">
<asp:Label ID="Label2" runat="server" Text="Description"></asp:Label>
</td>
<td class="td_left" colspan="2">
<asp:TextBox ID="txtDecription" runat="server"></asp:TextBox>
</td>
</tr>
</table>
</Content>
</asp:AccordionPane>
How can I do this? Some code example would be great on how to creat the accordinas ,text boxes dynamically and fill the values.
Web Forms :: Creating Imagebutton Dynamically At Runtime?
Aug 5, 2010I have a requirement whereby one or more image buttons need to be created in a user control at runtime. The number of buttons is determined from a database where a user can add one or more rows that contain an image for each button, so if a user adds 3 images to a table, 3 image buttons are created. Ive used this code but I get an error at runtime
The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases.
[Code]....
this is the usercontrol aspx
[Code]....
I basically want one or more buttons to render within the div in the usercontrol. Ive only got the code written for one button at the moment while I test the rendering, eventually they will be rendered in a loop of records taken from a database. Whats the best way to do this ?

View 1 RepliesSecurity :: Dynamically Selecting Membership / Role Provider At Runtime?
Jul 28, 2010I'm building an application that will be used by a number of different schools who want completely separate databases so I've decided to have multiple connection strings and membership/role providers in my web.config file. In my code, I'm trying to set which connection string and provider to use at runtime for the correct database according to the logged in user.
I'm coming into a lot of bits in my code that previously worked fine, that now don't. For example, I used to use:
[Code]....
But now that I've changed it to this, it doesn't work anymore:
[Code]....
The compiler tells me that AddUserToRole is not a member of 'r'. I've had similar problems not just with Roles but Membership too, like with calling CreateUser.
I'd still like to be able to use all these methods that I was using before which are extremely handy. I just want to be able to set the membership/role provider at runtime rather than use the default one. Am I doing something wrong? Is there a simpler way to go about this?

MVC :: Load Partial Views Dynamically At Runtime Using Html.RenderPartial?
Jun 8, 2010The following link describes the relationships between a Partial View and its parent in terms of ViewData: [URL] In relation to the text: "A partial view enables you to define a view that will be rendered inside a parent view. Partial views are implemented as ASP.NET user controls (.ascx).
When a partial view is instantiated, it gets its own copy of the ViewDataDictionary object that is available to the parent view. The partial view therefore has access to the data of the parent view. However, if the partial view updates the data, those updates affect only the partial view's ViewData object. The parent view's data is not changed"
how the parent view can make use of the new data added or existing data changed and updated, by the partial views? My question is around how to load partial views dynamically at runtime using Html.RenderPartial(...) whilst having one version of the data used and updated by the parent view and it's children.
