C# - Change Classes Based On Html Without Using Javascript?
Jan 8, 2010
I am not sure if is it possible or not but I have to change some classes of <li> tag which I am getting from ascx file.Now the condition which li to change or no is based on html that I am producing with the help of xsl(written in code behind).I know i can do this with the help of Javascript. But what if I don't wanna use javascript and want to do it wth the help of code behind itself.Is this possible let me explain this with the example also
<li>A</li>
<li>B</li>
<li>C</li>
I am getting A,B,C from the user control using Datagrid for it. now In this user control I have xslt and from this xslt I am getting html A,B.... and I want to change classes of li tag of A and B to sth else now.Can I do it withot using javacript. I want to write sth in my codebehind to acheive this.
When someone requests a web form, I want to use Javascript to see what browser they use, and then point to the correct css files with Javascript. What is the simplest way to do that.
For example, in my header of the html form, I have a link that says:
I'm looking at some site code on an XHTML doctype and from what I'm seeing the framework is ASP.net. The IDs in the HTML has a "$" in there. For example:
From a W3C semantic point of view the "$" is not valid in an ID or Class. IDs and classes can only contain alpha numeric characters in an XHTML doctype.
Is the the "$" a ASP.net naming convention referencing a web control or template item?
My class names are this annoyingly bright-blue color and I can't figure out which display item class names would fall into under the fonts and colors option.
I would like to be able to render a view in ASP.NET MVC so that all css classes in the elements are rendered inline in the tags. The sole purpose of this is to have email clients recognise html, as I believe that style must be inline for it to be recognised in email messages.
Is there any facility in ASP.NET MVC (or ASP.NET) that allows this?
I am new to LINQ. when we drag tables we get a dbml file and designer file.
For example DataClasses1.dbml and DataClasses1.designer.cs.
Once we have them then we can start using our LINQ Queries.
In my company project I do not see this designer files and instead there are .tt files which were used as templates to greate ABC.generated.cs files. Is this same as designer class?
I am following the Nerd Dinner tutorial as I'm learning ASP.NET MVC, and I am currently on Step 3: Building the Model. One part of this section discusses how to integrate validation and business rule logic with the model classes. All this makes perfect sense. However, in the case of this source code, the author only validates one class: Dinner.
What I am wondering is, say I have multiple classes that need validation (Dinner, Guest, etc). It doesn't seem smart to me to repeatedly write these two methods in the partial class:
[code]....
This doesn't "feel" right, but I wanted to check with SO to get opinions of individuals smarter than me on this. I also tested it out, and it seems that the partial keyword on the OnValidate method is causing problems (understandably so). This doesn't seem possible to fix (but I could very well be wrong).
I don't know if this has to do with how FindControl works or how scope works. But my base class is having a hard time seeing the fields of child classes. Currently I'm planning have the derived class set a property in the base class, but there are a lot of derived classes, so that isn't a very attractive solution.
I have a GridView with an alternating Css style. The GridView has a column called tradeId. What I want to show is an alternating colour based on a change in the tradeId. Is this possible? It will make it easier on the eye to group trades together by colour. Here's the GridView code as it is right now:
i have radgrid in my asp.net web page with some columns and rows in each row i have some checkbox that they are in one column. so i have one checkbox in each row and column.
i want when the check box checked, write in header that checkbox(in that column) write the number and so in that row, write the diffrent number. i want it occure client-side.
do you think it would be difficult to write a framework where mvc compares last html it output to the current html we want to output, and instead of sending the entire html, figure out what has changed and generate js code that will do the updating as compared to previous html? (presuming nothing was manually changed on the client using js).
I think I need to drop in some escape characters, but I'm not quite sure where. Here is the javascript function I'm attempting to call:
function setData(associateValue, reviewDateValue) { var associate = document.getElementById("Associate"); var reviewDate = document.getElementById("ReviewDate"); associate.value = associateValue; reviewDate.value = reviewDateValue; }
Here is the asp .net mvc line where I'm attempting to create a Radio button with a click event that calls the above function and passes data from the model as javascript parameter values.
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('<%=item.Associate%>','<%=item.ReviewDate%>' )" } )%>
The above throws a bunch of compile issues and doesn't work. A call such as the following does call the javascript, but doesn't get the data from the model.
I'm curious as to what people consider better practice, between duplicating model structure in the view model and using a mapping tool to move data between the two, or aggregate the model inside the view model, i.e. have a property on the view model class that is a reference to the actual model. Which is considered a better approach in general?
1) I'm currently working for HR application with security roles
2) for that I created dynamic menu and set data source to sitemapprovider control with "AspNetSqlSiteMapProvider"
Now my client requirement is to change menu's based on drop down selection so that menus will be minimum and quite user friendly.for that I did following steps:-
Created Drop Down contains list of all Roles provided him in Master Page In Menu1_MenuItemDataBound event I grabbed the roles for that node and compared with role selected in drop down and deleted that node now what i need is on drop down_selected index change I want to recreate menu.
