MVC Html.textbox - How To Validate Numbers Only
Apr 12, 2010With the HTML helper, how would you enforce number only without submitting? I know it was done with regular expression if you had a textbox in classic ASP.NET

C# - Auto Generate Javascript To Update Client Html Compared To Previous Html?
Jan 16, 2010do 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).
View 2 RepliesForms Data Controls :: Repeater ItemTemplate - If Eval(field)=0 Then HTML Else HTML
Feb 20, 2010The following seems reasonable, but it returns an error:
<asp:Repeater ID="RepeaterF" runat="server" DataSourceID="DSF" >
<ItemTemplate>
<%
If Eval("Item_Batch") = 0 Then
%><tr><td></td><td colspan="2"></td><td></td></tr><%
Else %>........
Error: "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
I am finding it difficult to accept that the whole Repeater approach has any benefits over just creating a loop in code, iterating through a recordset, and building a html table into a variable, then dumping it to the page. This repeater is spawning pages of code and objects, and surely this is all using up server resources.

C# - Pass Model Values As Javascript Function Parameters From Inside Mvc Html Helper Such A Html.Radio?
Jul 20, 2010I 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.
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<% String functionCall = String.Format("setData('{0}','{1}')", Html.Encode(item.Associate), Html.Encode(item.ReviewDate )) ; %>
<%= Html.RadioButton("Selected", item.Selected, new { onClick=functionCall } )%>

Html.ActionLink() Gives An Empty Link When Use It Inside Html.RenderAction()?
Feb 18, 2010I have a Microsoft MVC project with an action "Foo" whose view ("Foo.aspx") contains the lines:
<%= Html.ActionLink("mylinktext1", "bar") %>
<%= Html.ActionLink<MyController>(x => x.Bar(), "mylinktext2") %>
When I hit this from a web browser or load it from an AJAX call, it properly returns:
<a href="/bar">mylinktext1</a>
<a href="/Bar">mylinktext2</a>
But when I call the action from another view like this:
<% Html.RenderAction<MyController>(x => x.Foo()); %>
Then the links are rendered without targets.
<a href="">mylinktext1</a>
<a href="">mylinktext2</a>
Why would this be happening, and how do I work around it?

View 1 RepliesHow To Replace Html Tag In Html Editor With Specific String
Feb 9, 2010anyone knows how to replace a html tag in a string with specific characters:
e.g.
string s1 = "<span style="italic">inluding <span style="bold">other</span> tags </span>";
string s2 = "<span style="italic">inluding </span><span style="bold">other tags </span>";
i want to replace "span" with "bold" to "bOpen" and "bClose" and to replace "span" with "italic" to "iOpen" and "iClose" in both c# and javascript.
i did use regular expression to do that: res = Regex.Replace(res, ".*?", replaceHtmlBold); but it cant match the nested tag and none-nested tag at the same time.

HTML Codes In Strongly Typed HTML Helpers
Jan 20, 2011So, I am having a hard time getting this to work. I am trying to add some typographic HTML codes to some labels I have strongly typed to my model.
<%: Html.LabelFor(m => m.Name) %>
I am using data annotations to customize the DisplayName of the property:
[DisplayName("Your friend’s name")]
public string Name { get; set; }
However the actual code is being displayed for the label:
Your friend’s name
I have also tried just using the old write method:
<%= Html.LabelFor(m => m.Name) %>
MVC: When To Use Custom HTML Helper Methods Vs Html.RenderAction
Feb 10, 2010It's a little unclear for me on when to use a custom helper method and when to use RenderAction and also when to simply use ViewData instead. Some of their functions overlap slightly.
For example, if I were to create a Category navigation bar, would I create a new helper method and place that in some partial view? I had initially though of doing this, but I read on some blog to use RenderAction instead.
Assume the list of categories is coming from some data source.
