Example site: [UL] In the left hand part of the page(refine result pane), how can I produce links/list like that? What control is used in that?? I know it has to use the data queried on the first page.
I have a web page that loads in user-defined text from a database field into a label. This text may or may not contain HTML links (standard <a href> tags). I need a way to enumerate through the links and enable/disable certain links based on whether or not the person viewing the page is logged in or not (via a session variable).The html tags include a runat=server attribute and the text is standard formatted HTML. Since the text is being loaded into a label straight from the database, the links aren't loaded into the controls collection for the form - so, I'm not able to reference the links that way.
I want to know which code or technique is used to write the code written below in url which is "3rhgf6v4zbos16x" what is this and how it can be generated in asp.net?
Let's say I passed a couple of querystring to populate my datalist on another page. Then I want to filter/refine that datalist further by clicking on links( which are dynamically created depending on the data on the datalist) and when clicked will pass another querystring to create a new refined datalist.
Example: I clicked on a link that redirects to [URL], a datalist will be produced on another page. Then there is are link on the same page that go to [URL], [URL], then another datalist will be produced. how to code these links, what I have in mind is link (4), link (10). The numbers represent how many records it will display if that link is clicked.
I Have this code in my page, and I want that every NavigateUrl display another page like : simple.aspx? id=1, simple.aspx?id=2, ...
Where id = c Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Dim c As Integer = 0 While c < 5 Dim Label1 As New Label() Dim ltr As New Literal() Dim link As New HyperLink() link.NavigateUrl = "simple.aspx" link.BackColor = Drawing.Color.Aqua Label1.Text = c.ToString() ltr.Text = "<br/>" PlaceHolder1.Controls.Add(Label1) PlaceHolder1.Controls.Add(link) PlaceHolder1.Controls.Add(ltr) c += 1 End While End Sub
Not sure if the derived page is actually relevant to the problem here, but ran into an interesting gotcha on some code I'm working through at the moment.
I have a custom masterpage class, which derives from System.Web.UI.MasterPage so that it can be extended with additional useful properties. The page that that uses this masterpage has a declaration at the top (note the Page Title being set).
<%@ Page Language="C#" MasterPageFile="~/MasterPages/Landing.master" AutoEventWireup="true" CodeFile="Index.aspx.cs" Inherits="Index" Title="Welcome to the site" %>
In addition, the master page has stylesheet references in the head which are pulled from a CDN that is defined in a config file.
Now the example above obviously doesn't work, because the runat attribute in the head container means that the codeblock in the the link is static text, and renders as is, in the resulting html.
If I remove the runat attribute from head, the CDN works, but now I notice that the Title is no longer being set. If I debug, and try to access Page.Title in the Immediate Window, I get an exception:
// Using the Title property of Page requires a header control on the page. (e.g. <head runat="server" />).
So, is there a way to get the Page Title from the declaration, put my own title placeholder in the head and set it from the master page code-behind, or, is there a better way to dynamically set the CDN domain for the stylesheets? The only way I think I can do that is to build the entire html link tag(s) and append it to the header control, but I thought there might be a more elegant solution, so I'm asking here first.
I'm trying to do just as the title of this thread says:
I have a dropdownlist and to pick a client, and if there is no assignments (a different table) with that client in it I want the page to produce an error messagebox instead of going to the postbackURL.What would be the easiest way to do this?
I currently have a gridview that is displaying tabular data from an sqldatasource that looks something like this:
[code]....
Since I have an unpredictable number of categories coming from the database, I would like to continue to use a single datasource with only one query to the database. There is no editing, it is simply for display purposes. What's the simplest way?
I have a dropdown box control, populated by an Access data source, and linked to a form control which renders an appropriate record detail when a selection is made. All works as intended. My issue is that each rendering of the page shows the dropdown box carrying the link to the first record, with the detail portion of the page already complete with the information for that record.
I'd much prefer that the dropdown box would carry some text, like "Click to select..." leaving the detail part of the page empty at the first iteration of the page, allowing the user to pick the first record. I can't seem to find any way around this problem with the control or the data, unless I add a record at the top of the file that carries the text.
I need to produce a simple graphic which is a simple rectangle (bar) with a variable portion filled in to denote a percentage.
What is the best way to achieve this? I had a look at the .net charting tools but the nearest I could find to what I needed was the barchart which didn't quite seem to meet my needs for a single value.
I want to output some dynamic data from an ASP.NET website to Excel. I found that the easiest way which does not require to use Excel XML or to install Excel on server machine is to output data as a table and specify application/vnd.ms-excel type
I am trying to create a custom datasource control. I have been following this article to the letter (I think...). I have a skeleton / basic implementation of my datasource, however when I declare it in the markup and try to statically bind it to a gridview, I receive the following error:
The DataSourceID of 'grdVw' must be the ID of a control of type IDataSource
This seems extremely strange to me, since my datasource inherits from DataSourceControl, which in turn implements IDataSource. Even if I explicitly implement IDataSource in my custom datasource, it makes no difference. My Markup is:
Public Class DataBrokerDataSource Inherits DataSourceControl Implements IDataSource 'Have tried with this statement included AND excluded = same result Protected Overrides Function GetView(ByVal viewName As String) As System.Web.UI.DataSourceView Implements IDataSource.GetView 'Code here End Function Protected Overrides Function GetViewNames() As System.Collections.ICollection Implements IDataSource.GetViewNames 'Code here End Function End Class
Looking at the stack trace shows that the error originates at: System.Web.UI.WebControls.DataBoundControl.GetDataSource().
I have examined this method in reflector (see below), looking at this (based on the error message that I am getting) it appears to me as though the FindControl part is succeeding but that the source = control as IDataSource; leaves source as a null value, i.e. the conversion fails - But Why?
protected virtual IDataSource GetDataSource() { if ((!base.DesignMode && this._currentDataSourceValid) && (this._currentDataSource != null)) { return this._currentDataSource; } IDataSource source = null; string dataSourceID = this.DataSourceID; if (dataSourceID.Length != 0) { Control control = DataBoundControlHelper.FindControl(this, dataSourceID); if (control == null) { throw new HttpException(SR.GetString("DataControl_DataSourceDoesntExist", new object[] { this.ID, dataSourceID })); } source = control as IDataSource; if (source == null) { throw new HttpException(SR.GetString("DataControl_DataSourceIDMustBeDataControl", new object[] { this.ID, dataSourceID })); } } return source; }
All ASP.Net client validation messages can be shown as an alert by setting the ShowMessageBox="True" property on the ValidationSummary control. This works fine for anything that happens on the client.
For the custom validators that validate server-side I had assumed that what would happen is that when the page is returned to the browser, ASP.Net would inject some javascript to show the alert box. However this isnt the case.
If you had relied on the message box to show detail and just have a * next to the erroneous field (as per my clients req's) then it wont work as intended. Does anyone have a solution for doing this? What I want is a way to possibly override the ValidationSummary control to inject javascript onto the page or something like this.
I've written a ASP.NET app that I hope to sell to businesses, I could host the trial but it's designed to connect to the customers data so customers will certainly want to install it to do a successful evaluation.
I've never produced anything commercial before so I'm looking for advice on how best to limit the trial, a 30 day trial seems most common, do you simply rely on the clock of the PC/Server they install it on? keep in mind this is ASP.NET app so will be installed on their web server.
I have a C# project in Visual Studio that produces an aspx page. The code I am editing is in default.asp.cs. When I build the project a file default.aspx is produced. This file looks something like this:
When I make my web request most of this page comes back. But I want the page to return only plain text and not any of this HTML. How do I configure things so that nothing is returned except what I add via Response.Write calls in default.aspx.cs?
I have a hardtime to consume this web service as Web Reference or Service Reference: [URL] I'm using VS2010 and when I consume it as Web Reference, I can't use its method because in the reference.cs, it has these errrors:
// CODEGEN: The operation binding 'getStationCharacteristicSummary' from namespace '[URL]was ignored. The encoding '' is not supported.
If i consume it as WCF, then each time I call the service, it complained the encoding error. May someone try to consume it and help me with this.
I have a dynamic Table which contain 8 rows and 8 Colums
Table t = new Table(); TableRow rr = new TableRow(); TableCell cc = new TableCell(); and in the each Cell CC I add a dynamic Button(Or Linkbtn) LinkButton LB1 = new LinkButton(); LB1.Text = "AM"; LB1.ID ="Link1"; cc.Controls.Add(LB1); rr.Cells.Add(cc); LB1.Click += new EventHandler(LB1_Click); t.Rows.Add(rr);
i have a table with 8 rows , 8 colums and each cell contain a LinkButton (which diffrent in IDs) I want to add Lable in the same cell of this LinkBtn(LB1) which it clicked but I cann't What shoud I write here?
