Dec 19, 2010I have created a asp.net webpage for viewing daily downloaded newspaper, saved as a pdf file in a selected folder (~/NEWS/{0}) within the web root directory. Also i have a SQL datasource linked, where the news table has two columns viz: date and filename.
I want to create a tiled listview where the date text is visible on the hyperlink. on clicking the hyperlink, the file name is retreived for the corresponding date and the pdf file opens in a fresh page.
I have tried going to the item template in listview and replacing the label control with a hyperlink control, but then not able to successfully proceed ahead.
Forms Data Controls :: Dropdownlist Bound To Sqldatasource Adds Items Instead Of Replacing On Change?
Aug 26, 2010I have a series of dropdownlists on webform in ASP 4.0. The first drop down is filled upon load, and then when a user selects a value from that list, it populates the second dropdown. To accomplish this, I have a SQLdatasource with a parametersource of the first drop-down list control. This works great, except when a user changes their selection from the first drop down. It performs the query, but then adds the list of items to the ones that were already there from the previous selection, instead of replacing it with the new data. Here is the code:

Do I need to do something on selectedindexchanged to somehow "clear out" the previous datasource? I can't find anything about this online, although one person seemed to suggest it was related to using a master page. (which I am using).

Forms Data Controls :: How To Push Down Outer ListView From Nested ListView Control
Mar 13, 2011I have anested ListView control. I also implemented a jQuery to automatically expand the TextBox control inside of the nested ListView Insert Template. The problem is, when the Textbox expand, the outer ListView control is not; therefore, the Textbox control expands underneath the buttons of the outer listView control. How do I expand the outer ListView control as the nested ListView textbox is automatically expand? One great example is in Facebook where if I add a response comment, it'll automatically push any comments below mine down. If nested Listview control is not the best way to do this, what are my options?

Forms Data Controls :: Datalist Control Bound To List Of Objects?
Mar 17, 2010How can I bind a datalist control with a list of objects. I have a list of objects that contain a name, desc, and url for menu commands that I am trying to show in a DataList. I am getting the list from a WCF service so I have a list called something like menuList which consists of a List<MenuCommands>. I then do a menuDataList.DataSource = menuList and then a menuList.DataBind but nothing is happening. What am I missing here? I need to use a DataList because I need the commands to be selectable.

Forms Data Controls :: Reset Data Bound User Control Shown With Ajax Pop - Up Extender
Nov 1, 2010I have a web form, and an "add vendor" button. Click the button, a modal dialog pops up (ajax:ModalPopupExtender). User selects one of two radio buttons which shows a data bound asp:View in an update panel - this view is data bound to a single row and must be populated by the user. However I also want to provide a cancel button which should close the modal dialog and reset the bound view.
However what is happening is that the ModalExtender closes, but when the "add vendor" button is presented again, it's still bound to the same data. Do I need to clear my data source? How so I reset the forms/views so that when the 'add vendor' button is clicked again the form is presented as it should be (IE the 2 select options, picking one re-binds the asp:View)?

Forms Data Controls :: Using Event For Data Bound Control Vs Data Source?
Jan 1, 2011I've been using the Item Inserted event for my data controls, such as details view. I'm wondering if there are advantages to doing this with the data sources instead of the data control. There is a lot of overlap in the events provided by these two types of controls. Are there advantages to using the events raised by the data source instead of the ones raised by the data control itself. Should I be using the events raised by the data source instead of the control used to enter the data?

Mar 24, 2010I need to develop a custom data-bound control which will contain, few text-boxes, drop-down lists, labels, and other standard web-server controls. And, I want to be able to load this control from a web page on button click.

Also, the data in the child control should retain their value on postback. What approach should i follow?

View 3 RepliesForms Data Controls :: Giving The Panel Control A Dynamically Bound Value (3 Way Nested Gridview)?
Jan 5, 2010I have a 3 level deep nested gridview. The expansion/contraction of each record was originally done with javascript. There were html <div> tags around each gridview. Since these were HTML div tags I could give them IDs that were dynamically bound to record ID value within the database. I then had onclick buttons that passed in a bound record ID value that coresponded to the appropriate div tag that needed to be expanded (e.g. display: inline (show it) or if it is already inline then display: none).
This worked beautifuly. Unfortunatley I wanted to be able to do in-girdview editing of the child records. When expands a parent record and clicks to edit a child record the OnRowEdit event fires which automatically generates a postback and resets the variables within the JavaScript. THEREFORE THE ENTIRE GRIDVIEW STATE BECOMES CONTRACTED.
So finally I decided to change the div tags to <asp: Panel> and the onclick images to .net clickable images (all .net objects no framework). This works because the state is remembered within each postback. However, the problem I'm having is I can't dynamically bind ID's for panel since this is not allowed. HOW CAN I GIVE THE PANEL <% Bind("id") %>. THAT I CAN REFER TO SO I CAN OPEN THE APPROPRIATE PANEL.

Type Of Data In GridView / Listview Bound - Template And Auto Generated Fields
Aug 18, 2010Background: I'm populating lots of asp.net c# GridViews and ListViews from a database and subsequently users may export them to Excel. I want export as native Excel (not html). I can't use office automation, and I'm using JET which works fine. I have no control over users' machines. Question: When doing the export, you have to tell Jet what type each field is, in my case "text" (varchar) or "numeric" (double). The difference is that if you export a numeric column, the users can sum the data in Excel, where as strings are exported with a leading apostrophe and so are not much use in arithmetic.
Currently I parse the first data row of the Grid/ListView, check if each value is numeric or text, and assign a type to the column accordingly. That works, except for when I have something in the first column which looks numeric but in fact is a text string. I don't want to parse every row in order to be sure I have the correct data type as some of these exports are quite large. When I load the Grid/ListView from the database, the database certainly knows what type each field is. So my question is... how do I extract the type of the database item behind a a Grid/ListView item? I could explicitly code it as an attribute on the item, but that's duplicating information I already have, if only I can get to it. I know that where I have a DataTable then I can get the underlying type from that, but mostly I don't have tables handy, just the Grid/ListView. Note that Jet will throw if you try to insert an empty string into a nullable numeric column. The way to do this is to omit that column name from the insert statement, or output a zero.

View 7 RepliesDataSource Controls :: Sorting A ListView Bound To LinqDataSource Based On Child Object?
Jul 22, 2010This was a pretty disappointing moment - when databinding, using Eval("Contact.LastName") would work. It nicely evaluates the related Linq object's member LastName. If the "Contact" object is null, no error is thrown... instead the field is simply null.
However, the same does not hold for sorting - if there exists a null entry (this object does not have a Contact) then the LinqDataSource throws a NullReferenceException. This means that, if you ever have nulls on your foreign-key objects, you can't use sorting headers in the ListView.
This makes the feature moderately useless - I have to roll my own properties for every single field I'd ever want to sort on. That's insane.
