I am new to MVC. why HTML helper methods are inside asp server tags?
for example <%=Html.Textbox("Textbox1")%>
are they equivalnet to asp.net web form server tags. Like in web forms we have
<asp:TextBox runat="server"></asp:TextBox>
If someone can kindly explain.
It'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.
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.
<%= 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 } )%>
I have a SharePoint web part that I wrote in C# which is used to display SQL Server data based on user selections. I pull the data with a DataReader, fill a DataSet with it, and set that DataSet as the DataSource in a GridView and add that control to my page:
GridView outputGrid = new GridView();
outputGrid.CssClass = "OutputGrid";
outputGrid.DataSource = flipped_ds1;
outputGrid.RowDataBound += outputGrid_RowDataBound;
outputGrid.DataBind();
Controls.Add(outputGrid);
This gives me a simple HTML table with a declared CSS class and that's about it. The only problem I'm facing is that line breaks in the data fields are not being rendered at all. I'm simply getting a block of text that ignores the breaks that are present in the database when it's rendered to HTML. In stepping through my code, I see that the newlines are coming in as text in the form of "". I tried a regex:
[code]....
I have to set image on the basis of fields value coming from db. I want it to achieve via. tags <%# %>. For example i have collection binded with grid. It has a Field called Online which is boolean. So if the value of Online is true then the green.png will be set as path of asp:image control else grey.png will be the path of the asp: image control.

View 2 RepliesI'm trying to insert some html 'div' tags inside a tabcontainer from server side. I haven't seen anything similar on the net. Here's the situation:
I have the following TabContainer on a form:

<cc1:TabPanel HeaderText="Person">

<div id="Test">

How can I acheive that? If it's not possible, what other alternatives do I have? The most important requirement for me is to allow the user to remove the data by clicking on it.

I'm trying to develope a collapsible panel control with designer.
I have the following two classes:
[Code]....
and this one:
[Code]....
In fact, the designer class is a copy of a sample class in MSDN and I only tried to customize it to work for me. I'm not sure if all methods are necessary or not.
I have the following two questions:
1- When I use this contrl in design mode, I can add or delete controls to it, in the html view, tags are not updated. so when I close the page and open it again, all changes are lost.
2- I have added this control to the same asp.net project that is using this control. Isn't there any way to have this controil in tool box?
I have to break a HTML content string in to multiple lines. And each line should have some fixed characters, 50 or 60 Also I don't want to break the word..or html tags...

<p><em>"Text goes <font color=red>Hello world</font> Text goes here and Text goes here Text goes here 1976."</em> </p>
How can I acheive this in C#?
I was wondering if it's possible to render an Html Helper in a View inside a codeblock. So instead of:

And have this render. Of course as it is, it wont render, so is there a way to programically decide if a textbox can be added without having to have a million delimiters in the page to accomplish this?
I am trying to create 2 Html helpers but that use the String Type as in MVC 2.
1. Html.FileFor Would render something like: <input type="file"
2. Html.Buttom and Html.Submit that would render <input type="button" or <input type="submit" In this case I suppose it makes no sense to have the For.
I know how to do (2) unless there would be something more than rendering the help and defining the Html attributes. However (1) I don't know how to do it
Can we set an id attribute as I would for something like a table column via: for an html dropdown list element that is created with a helper such as:
<% for (int i = 0; i < Model.Trx.TransactionHolidayCityCollection.Count; i++)
{%>
<%= i > 0 ? "," : "" %>
<%= DropDownData.HolidayDays().ToList().Find(item => item.Value == Model.Trx.TransactionHolidayCityCollection[i].HolidayCityID.Value.ToString()).Text %>
<%} %>
How can I remove all html tags and script tags? consider also short tags like unclosed tags
<script>blah...</script>
<body> aaa<b>bbb</body>
This should return aaa bbb.
notice that all the contents inside the script tag is ignored.
Is there a way to retrieve the client side ID for a model property similar to how the helpers like LabelFor etc generate the ID? For example, I have a model with a DateOfBirth property. I want to hook up that field to a jQuery DatePicker. Normally, I would hook up the date picker like this:
[Code]....
This works fine but hard codes the DateOfBirth property name. Ideally, I would like to use this:

Is this already available out of the box somewhere? I just created an extension method on the HtmlHelper class that does exactly this, but I wondered if there was already something built-in so I don't have to reinvent and test the wheel.
