I need a for below code
<HTML>
<Head>
</Head>
<Body>
<div id="div1" runat="server"> My Name is Guvera </div>
</Body>
</HTML>
In the above HTML i need to take a string "My Name is Guvera" using Asp.Net code.
In a C# codebehind, i am calling a web service that returns an HTML blob that i need to stick in an IFRAME. I suppose that i can write it to a temporary file and point the IFRAME src to that, but is there a way to either (a) write the string to the IFRAME directly, (b) point the IFRAME src to the string somehow (maybe with streams), or (c) some other way? I want to avoid writing this string to a file.

How can I get/retrieve html link (<a> tag) in my codebehind?
I have this link in the body of my website:
<a class="link1" id="link1" href="home.aspx>Test</a>
In my codebehind (Page_Load) I want to add a (Css)Class to it.
Is there a way of selecting returned values from a call to an sql database in the code behind? For example assume that I used the following to select values from a table called Products;
SELECT Price, Qty, Numbersold FROM Products
How can I now get the returned values e.g. Price in the c# codebehind and display it in a textbox? I know that in the asp markup that I can use EVAL and Bind statements to do this for example I can do Eval("Price") but is there a way of getting any of the selected values (Price, Qty or Numbersold) in the codebehind?
I know that I can use three separate select statements and make three separate calls to return each value and then do something like the following
Price = Convert.ToInt32(myCommand.ExecuteScalar());
I'm trying to create a table with Listview and one of the fields I'm using is supposed to show a hyperlink to a more detailed view of the data shown, how I want to do that is by using FindControl on the ID of that item and then changing the value into a hyperlink of the detailed view page with a querystring attached, the problem is that I have no idea how to re-insert that data back into the listview field, which looks something like this:
<ItemTemplate>
<td>
<asp:Label ID="ViewLinkLabel" runat="server"
Text='[insert Link Here]' />
</td>
</ItemTemplate>
I'm still an amateur in ASP.net, and if any of this seems too convoluted when there's a much easier to do this that I don't know about.
i would like to load a banner on to the page based on the registration count we have in the DB. if the registration count is >70, i will have to load banner2 on to the page. i am doing like this On the webForm.aspx
<img src="images/banner1.jpg"
runat="server"
id="imgs"/>
in the code behind
protected void Page_Load(object sender,
EventArgs e){
if (!Page.IsPostBack)
{
if(isSessionOneFilled())
{
imgs.Src = "images/banner2.jpg";
}
}
}
The above code works. is it Good Programming to load html files from codebehind? is there any alternative way? how does this impact when internet speed is slow?
I have an asp.net page where i have the below markup.Basically this markup is generated from codebehind by reading records from a table and looping thru them.For each record in table,there will be a div block. Basically this form is to read/show settings for a user.The settings entries are stored in a table.
<div id='divContainer' runat='server'>
<div id='div1' runat='server'>
<table>
<tr>
<th>Name</th>
<td><input type='text' id='txtName1' value='something' /></td>
</tr>
</table>
</div>
<div id='div2' runat='server'>
<table>
<tr>
<th>Domain name</th>
<td><input type='text' id='txtName2' value='something' /></td>
</tr>
</table>
</div>
<div id='div3' runat='server'>
<table>
<tr>
<th>URL</th>
<td><input type='text' id='txtName3' value='something' /></td>
</tr>
</table>
</div>
<div id='div4' runat='server'>
<table>
<tr>
<th>Some other value is enabled ?</th>
<td><input type='checkbox' id='chk4' /></td>
</tr>
</table>
</div>
</div>
The id's of each input element will be unique. Now in codebehind i want to read the values of each input elment to save the changes user made.How can i read the elements here ? Since the mark up is generated in codebehind as a string and appended the the INNER HTML of the external div,I cant read values like we do for a control which we drag and drop in the IDE.
I'm interested to hear from other developers their opinion on an approach that I typically take. I have a web application, asp.net 2.0, c#.
What I usually do to write out drop downs, tables, input controls, etc. is in the code behind use StringBuilder and write out something like sb.Append("
I don't find myself using to many .net controls as I typically write out the html in the code behind. When I want to use jQuery or call JavaScript I just put that function call in my sb.Append tag like sb.Append("td...onblur='fnCallJS()'.
I've gotten pretty comfortable with this approach. For data access I use EntitySpaces.
I'm just kind of curious if this sort of approach is horribly wrong, ok depending on the context, good, time to learn 3.0, etc. I'm interested in learning and was just looking for some input.
Edit
After reading the comments here it sounds like I should take a look at MVC. I've not done that yet. The only hesitancy in doing so is that the existing project is just that, existing. There is a lot of code already done the way I explained and it is hard to imagine what would be involved in changing it, advantages of doing so, and just learning what that would take.
The other thing I'm taking away from the comments is that my code behind should really not include much of the sb.Append code, whereas now it is filled with it in numerous functions. To me it is not messy but that is because I know what each function does and can look at it and see, oh that writes out x, y, and z.
It's not uncommon for me to just have a div on the .aspx part and then build up the .innerHtml of that with the StringBuilder in the code behind.
i have this string:
string foo = "<p>temp</p>";
how can i show it on my page without using Response.Write(foo)
I want to reset all the fields and values in codebehind on buttonclick.
View 5 RepliesI have a span control which I am filling using Jquery. At the page load I want this span say id1 to be invisible and depending on some conditions I am making it visible via jquery itself.
When I make id1 runat = server and try to access id1 from codebehing, then I get an error in Jquery.
Hence I need a way to make id1 invisble at the load time itself.
I have already set id1 = invisble in HTML, But still I see this control on the page till the time jquery fills the entire data.
in my proj i have a grid view which consists of name and droppown list as shown below:
<asp:GridView ID="gvJobs" runat="server" AllowPaging="true" AllowSorting="true" AutoGenerateColumns="False" OnRowDataBound="gvJob_RowDataBound" OnRowCommand="gvJobs_RowCommand" >
<Columns>
<asp:TemplateField HeaderText="Jobs" SortExpression="name" HeaderStyle-HorizontalAlign="Left">

when i click the dropdown list it is postbacking(since i made auto postback=true). on that time i am unable to get the selected value from dropdown list.
I have a Sidemenu item in my ASP.NET application like below. There are two types of users in my application (Associates, Managers).When ever Associate Login then I have to disable Manager link. I am not able find visible property in codebehind since it is a HTML control. So need your support how to handle this
<ul>
<li><a href="Associate.aspx?val=Tests&index=0" id="lnkAssociates">Associate</a></li>
<li><a href="Manager.aspx id="lnkManager">Manager</a></li>

I'm using VS 2008 and can't seem to get intellisense to reconise Public variables declared in my codebehind.I start a new ASP.NET Web Application project, named something other than "WebApplication1". In my default.aspx.vb codebehind, I declare, say, "Public MyValue As Integer = 10", at the class level of course.Then, in my default.aspx page, within the body tag, I type "<%= myvalue %>"No mater what I try, it refuses to recognise "myvalue" as a valid variable name, however the code DOES compile and runs perfectly. Everything else seems to work fine.
View 3 RepliesI added some javascript to fill in a dropdown and it works wonderfully. However, when I try to access the value in codebehind to submit the data, the value shows as null. (string strValue = ddlName.SelectedValue;).

I would like to store some business flags (like: isFavorite, isOnLive etc.) per an html table row that won't be visible to user.
In practice, I have a simple ADO.Net DataTable on my code-behind which is used as a data-source for a asp.Net GridView control.
This table contains some business flags on its 0th, 1st, 2nd columns.
I need to store those columns on the rendered HTML of the grid-view -so that I can reach them via JavaScript- but I do not want them to be visible.
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 } )%>
is this right? i am trying to display value in input box dynamically?
can anyone advice me is this corect approach? but still I am getting here only + + in input box?
I have static html paypal buynow button that works great, but it's static.
[Code]....
But it is possible to change the values for the hidden inputs from .net codebehind code? I found this post which takes a different approach of sending these hidden fields instead as a query string to paypal. Not sure I like that though as would this not possiby explose some of those fields like the return page?
http://www.makaistudio.com/mksBlog/post/ASPNet-and-Paypal-buy-now-button-Offer-discount-at-checkout-in-code-behind.aspx
Basically what id like to do change the important parts of the button and info I'm sending to make it dynamic.I know I can do something like this in the markup, but that would mean having to fetch data mulitple times was hoping I could somehow adderss the field values directly in the codebehind. Or possibly dynaically generate and insert the entire changing input type fields from the codebehind
<input type="hidden" name="invoice" value="<%= getinvoice()%>">
Possible to add them with something like this: myform.Attirbutes.Add (???). If so how do I contruct these input types in .net?As far as return logic security, I've tested that it's solid, i just need to automate the button process so I don't have to create a buy now page and button for each product.

I have written a ajax function that I will check the result of a div tag to see if I want to hide the partial view and show the result. The result depends on what is coming back from the controller and the html(result variable). It should only go to the else statement if the return html string does not contain a div tag with id "valRegno". I do not know how I can find the div tag and check if it is there or not. The "result" htmls are nice and show me the details I am intrested but I can not extract it from the html string.
Here is the code I have come up with:
