Assign Label To A Text Value Returned From A C# Method?
Aug 9, 2010
I have several labels in my application, and I need to manipulate every single one of them. So, I thought the easiest way would be to simply call the manipulating C# method from the aspx page when needed, but oh, I was wrong. I have spent a couple of hours now trying to figure out how to do this, but I have not come to a solution ..
protected string ManipulateLabel(string label)
{
return label+" some value";
}
I do not wish to assign each label to value directly from code behind (normally I would do it like this but this time there are so many labels that need a manipulated value that it simply would be too hard updating the application in the future).
When using the code behind, the application simply prints "<%= ManipulateLabel("Information") %>" on the page, which is not what I want :( Also, if I use:
public static string Greet(string name) { string greeting = "welcome "; // is it possible to pass this value to a label outside this static method? string concat = string.Concat(greeting, name); //error Label1.text = concat; //I want to return only the name return name; }
As you can see in the comments, I want to retain only the name as the return value, however I want to be able to take out the value of the concat variable to asign it to a label, but when i try the compiler refuses, can it be done? Is there a work around?
I have a label in aspx page. I am trying to assign text to that label according to my search criteria. My problem is if i put that label (lblMsge) inside I am unable to assign the text from code behind. if i put that label outside the tr its working fine but the display is not proper. I tried by putting that label in div tags also.Here is my code.

i am using JQuery UI Autocomplete with asp.net textbox.AutoComplete works right.but how can i assign selected ID of returned Data to an hiddenField?My server Side Function returned list of objects that contains (this is an example) :
public List<Employee> GetEmployeeList() { List<Employee> empList = new List<Employee>(); empList.Add(new Employee() { ID = 1, Email = "Mary@somemail.com" }); empList.Add(new Employee() { ID = 2, Email = "John@somemail.com" }); empList.Add(new Employee() { ID = 3, Email = "Amber@somemail.com" }); empList.Add(new Employee() { ID = 4, Email = "Kathy@somemail.com" }); empList.Add(new Employee() { ID = 5, Email = "Lena@somemail.com" }); empList.Add(new Employee() { ID = 6, Email = "Susanne@somemail.com" }); empList.Add(new Employee() { ID = 7, Email = "Johnjim@somemail.com" }); empList.Add(new Employee() { ID = 8, Email = "Jonay@somemail.com" }); empList.Add(new Employee() { ID = 9, Email = "Robert@somemail.com" }); empList.Add(new Employee() { ID = 10, Email = "Krishna@somemail.com" }); return empList; } and this is ASPX Code : <form id="form1" runat="server"> <div class="demo"> <div class="ui-widget"> <label for="tbAuto"> Enter Email: </label> <asp:TextBox ID="tbAuto" class="tb" runat="server"> </asp:TextBox> </div> </div> <asp:TextBox ID="TextBox1" runat="server"> </asp:TextBox> <asp:Label runat="server" ID="lbl" Text=""></asp:Label> <asp:HiddenField runat="server" ID="hidid" /> <asp:Button ID="Button1" runat="server" Text="Button" /> </form>
here is my jquery Code :
<script type="text/javascript"> $(function () { $(".tb").autocomplete({ select: function( event, ui ) { // now assign the id of the selected element into your hidden field $("#<%= hidid.ClientID %>").val( ui.item.ID ); }, source: function (request, response) { $.ajax({ url: "Default.aspx/FetchEmailList", data: "{ 'mail': '" + request.term + "' }", dataType: "json", type: "POST", contentType: "application/json; charset=utf-8", dataFilter: function (data) { return data; }, success: function (data) { response($.map(data.d, function (item) { return { value: item.Email } } ) ) } , error: function (XMLHttpRequest, textStatus, errorThrown) { alert(textStatus); alert(errorThrown); } }); }, minLength: 1 }); }); </script>
And this is My WEb Method Side Code :
<WebMethod()> _ Public Shared Function FetchEmailList(ByVal mail As String) As List(Of Employee) Dim emp = New Employee() Dim fetchEmail = emp.GetEmployeeList() Return fetchEmail End Function
Anyone have this problem. When you write a ex. label name or label text in the properties window, it look like its updating the text before you actually are finish. This make you type over what you allready wrote. Its not a big problem,
It is working correctly...But It is not showing error message.So how to show the error message that is returned from the above condition ValidateField()...If the condition not satisfied i want to show a error message like length should be greater than or equal to minimum length and so on ..

I am trying to develop the single page in asp.net web mobile application as code behind c#. I have took the Mobile select list control on page.It has items, 1,2,3,4,5,6,7,8...20. I want it should be assign the selected value of select control to mobile label control situated on page (Mobile Form). As per i know I have to code this on OnSelectIndexChanged Event at code behind. ok? but nothing like this happening. I have written the method (Event) on code behind. I don't want to write javscript or on .aspx code ( not want any client code). I want to conduct functionality on code behind. How should I can achieve this.? As I found Select List control of Mobile toolkit not generates the server side event. What I have to do?
I have an entry page that contains a datalist. I also have an ascx user control page that when it runs on page load, renders an html table template which contains category information from an SQL self referencing table. When the SQL query run on page load, it bind the results to a datalist called dlCategory, and repeats for all rows that have no value in a field in this SQL table called ParentCategoryCode. The SQL table is called ServiceRequestCategories and basically consists of CategoryCode, CategoryTitle, and CategoryDescription, and may or may not have a ParentCategoryCode associated with it.
Records without a ParentCategoryCode are top level categories, and anything that has a ParentCategoryCode are second or third level categories. The way I have the data set up, it ends up being 4 rows that are returned and rendered as 4 html tables. Each one of these is tied to the user control, and each user control runs another datalist, and shows all CategoryTitle values for each Category that has a ParentCategoryCode (second level categories). This works when you click on a LinkButton for any CategoryTitle. This all works fine.
My question is, how can I use an SQL select query to plug the value of the CategoryTitle into a label called lblCategoryBreadCrumb on my main entry page? Here is my code, but it does not seem to work.

For a web application developed on ASP.NET, we are finding that for user control files (ascx) we are returning long strings as a result of method calls. These are embedded in the ascx pages using the special tags <% %>When performing memory dump analysis for the application, we find that many of those strings are not being garbage collected. Also, the ascx pages are compiled to temporary DLLs and they are held in memory. Is this responsible for causing the long strings to remain in memory and not be garbage collected ?
in my asp.net+vb+access web i am having a page in which i am counting and displying the numbers in text boxes/labels. it works fine.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim connectString As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & _ "Data Source=C:webWing.mdb" Dim con As OleDbConnection = New OleDbConnection(connectString)
[Code].....
i want to amend the value with the value of the text boxes that i had tried manually it works fine.
I have Template fields configured for Gridview. The gridview is using an objectdatabsource to bind itself. I have the gridview configured to use Templatefields which then contain tables to display the information. This works fine.
My question is, is it possible to change the text of the label if certain criteria is reached. If "NumberOfDwellings" is 1 then change the label to read, "1 Dwelling". Where-as if NumberOfDwellings has more than one then it's "3 Dwellings".
I have been messing about with this for hours surely this should be an easy task ....... I have a stored procedured that creates a invoice on a Quotetable one of the parameters is a output parameter Invoice Number this is passed to a label. (Label1) This works great.
I then need to add items to the invoice on a item table so my next stored procedure should take the value of Label1 and update the foreign key quotenumber on the itemtable with the value from label1.
On the aspx page I have a small section for a gridview which shows the current quote with however many items on it using the control
[Code]....
On the ASP page the control for @Quotenumber = Label1 but I get the following error
'Conversion failed when converting the nvarchar value 'Label' to data type int.'
