Forms Data Controls :: Reset Data Bound User Control Shown With Ajax Pop - Up Extender
Nov 1, 2010
I 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)?
Is it possible to use the ajax calendar extender with the listview control specifically within the edit tags . .Net is not throwing any errors but the extender is not working.
What is the best way to create a data bound ASP.NET user control? I have a user control that contains a drop down list and three label controls. I would like to data bind the drop down list, and have the label controls display different properties of the data source. I have Googled for an example of IDataSource and User Control, but cannot find any good information. This must be a common use of a user control?
I'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?
I have a ListView control that only displays one record at a time. I have a LinqDataSource that can return one or more records. I have a function that determines the number of records and returns a psuedo random number between 1 and the number of records returned. When the page first loads, I want to display a random record. After that, I want the datapager to move the user normally through the records.
In my Page Load Event, if Page.IsPostBack is false, I get the random number. Let's say for simplicity I have 15 records and the randon number generated is 6. How do I tell the LinqDataSource to display the record at index 6?
I 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. When the user enters any data to any of its child controls, i should be able to save, and also retrieve when the data-bound control is loaded again. Also, the data in the child control should retain their value on postback. What approach should i follow?
How can i reset ajax mdal popup extender.. If user first open the modalpopup on the button click then do some events in popup and after closing the popup if user next time opens the popup i want it t to be refershed and same as i have created..

How 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.
I have a masked edit extender extending a text box. I enter the date 01/01/0001 then change a selection on a drop down list inside the same update panel with the autopostback property set to true. The date is changed to 01/01/1910.
I have a situation where I currently have a HyperLinkColumn control that I would like to modify to have a Label or simple text appear in the same column as the hyperlink. I tried setting this in the ItemCreated event but encountered the following error message
I 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.
I am quite new to asp.net. I would like to ask for some advice on how this scenario can be achieved. Here is the problem:
I have a 5 gridviews on my page. In each gridview, I have two important columns. They are SellerID and BuyerID. Because I already have too many gridviews on the page, I want to load a webuser control with a modalPopupExtender when either SellerID or BuyerID is clicked. That is to say if a user select a SellerID, the details information about that SellerID should be loaded with DetailView from the user control and if the buyerID is click, the details information about that buyer should be loaded with another detailview from the user control as well.
My problem is I do not know how to get the Selected Value from the gridView since the DetailView is in the WebUserControl. One more thing, both SellerID and BuyerID are in the same GridView, so how can we distinguish when a user select a SellerID or vice versa.
i am new to asp.net and need some help with writing a user control that fits the following specification:
i have a list of properties. each property is a string triplet (type, name, value). TYPE can be "boolean", "string", "int" with VALUE taking appropriate values.
so a list of properties would look like: {("boolean", "isMember", "true"), ("int", "age", "39")} .
i need to display the list of properties in a table with a corresponding control for each value type
("boolean" in a CheckBox, "string" "int" in a TextBox)
and be able to to edit the values. I wrote a small control that displays a single property. It puts the NAME in a Label and depending on the TYPE inserts
the value in a TextBox or CheckBox and then puts that in a PlaceHolder. I could afterwards display the list in a table when a button is clicked.
I would like to know how i could display data from an itemtemplate or any other form views/data-bound controls without having it render in tables? i know theres control adaptors, but is this reliable and will it work with asp.net 3.5?
I have to display data in following format in asp.net. Please suggest me the best suited control for the same. Any help with code, rather than just the control names
I have an issue with gridview and ascx's inside. Into the item template I'm dynamically loading ascx files depending on the row hiddenfield value. Ascx control is then "opened" in panel with modalpopup extender. The issue is ascx control with ceratin programming logic behind does not postback in this scenario.
