AJAX :: Creating Static Datas For Every Row To A Dynamic Datalist?
Jan 4, 2010
I have created a data list, which displays the details of 3 students in a horizontal manner. I have retrieved the data's for the data-list dynamically.And it displays as shown below

...Like this. But I want to make a header for every row as shown below.
I must create a few DataLists programmatically. All of them will share the same ItemTemplate. Is it possible to define this ItemTemplate in .aspx file, using wizard etc, and then create DataList programmatically and assign this template? There is information in the internet how to define both ItemTemplate and DataList programmatically, but I want to define the ItemTemplate statically and only DataList programmatically and then assign the template to it.
The problem that I encounter is that ItemTemplate tag only works inside some control tag. It looks like it is impossible to define an ItemTemplate (like e.g. resource in Silverlight) not associated with any DataList, using the wizard and design tools, and then reference this template in code during runtime.
I want to create dynamic datalist control with item template in a for loop.
Example: In my database, I have 20 Categories and 100 products. Each categories have some products. Now I want to show 20 categories all together in my page and it is not specific that categories will remain same. It can be increase or decrease. I am taking CategoryID with for loop and now I want to bind datalist according to the count of for loop.
As a workaround for the fact that asp:Checkboxes don't have values, I am attempting to dynamically create the ID's of checkboxes in a DataList so that it inserts the primary keys into the control ID. This is surprisingly difficult.
I have placed a PlaceHolder in my DataList ItemTemplate, then in the ItemCreated I create the checkboxes using string.Format("Checkbox{0}", DataBinder(e.Item.DataItem, "ID")). The problem is that this only works in a non-postback condition, as on postback the DataItem is null. And of course ItemDataBound isn't called on PostBack so that won't work either.
I can't seem to find a good way to handle this short of if (IsPostback) dataList.Bind(), which i don't think is a good way to do it.
I have a panel with two static buttons. A "Ok" button and a "Cancel" button". Depending on ther client actions, one or more controls will be added to the panel. Is there a way I can add the dynamic controls above the static ones?
I make one datalist and put data in it and add one button for selection. When you click the button and you can select the necessary data.
The following is my code:
Protected Sub ImageButton20_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton20.Click Dim myConnection As SqlConnection Dim myCommand As SqlDataAdapter ' Create a connection to the "pubs" SQL database located on the ' local computer. myConnection = New SqlConnection("server=localhost;" _ & "database=pubs;Trusted_Connection=Yes") ' Connect to the SQL database using a SQL SELECT query to get all ' the data from the "Titles" table. myCommand = New SqlDataAdapter("SELECT * FROM Product Photos WHERE Product Name= FOOD ", myConnection) ' Create and fill a DataSet. Dim ds As DataSet = New DataSet() myCommand.Fill(ds) ' Bind MyDataList to the DataSet. MyDataList is the ID for ' the DataList control in the HTML section of the page. DataList1.DataSource = ds DataList1.DataBind() End Sub
Here is what I have done so far. I have a datalist to show notifications. The datalist is bound to an sqldatasource.
I have tried to use a collapsible panel extender in the datalist to hide or show message, but the designer could not render the datalist because of the collapsible panel control. It gives an error "Unknown server tag asp:CollapsiblePanelExtender"
I have datalist menu, when I click on each menuitems a new Dynamic Ajax tab is created. my problem is : if I click on a menu item for several times, dynamic tab is created for several times too,however I want to create my tab just one time. and if I click again on menu item the previous tab that was created before is shown. here is my code to create tabs:
I did some research after posting. All I found was simple examples for no-layer architectures, like connecting to a database from your aspx page, so, in a corporate environment, it is unnaceptable.
I need to call a server-side method (using ASP.NET Ajax) in a 3-layer architecture.
For example, my Default.aspx contains a method LoadProducts().
[Code]....
[Code]....
This cannot change. There is no way to convert Business and Data layers to static.
How can I call the LoadProducts() method using ASP.NET Ajax?
when we declared as static then we will not create the object to call the static method. then my doubt is how is call the static constructor after creating the object?can you explain cleary?
I am creating a static variable and adding to session.This variable has value that is user specific. Now I am getting a problem with this users are complaining that they are getting values that should be another users. It's like a mix up with session. Could this be because of static variable declaration?
I am using jQuery to call PageMethods. For certain operations, the current user credentials must be validated and for other operations, I need to call other static methods. Here is some sample code:
Sample #1
[WebMethod] public static void PostComment(string comment) { UserAuth auth = new UserAuth(); if (auth.isAuthenticated) { //Post comment here... } }
Sample #2
[WebMethod] public static string GetComment(int commentId) { commentDto comment = //get comment data from the database... string friendlyDate = ConvertFriendlyDate(comment.commentDate); return friendlyDate + " " + comment.text; } public static string ConvertFriendlyDate(DateTime commentDate) { string friendlyDate = //call static utility method to convert date to friendly format return friendlyDate; }
Will I be safe using these kinds of operations? Am I better to drop page methods and just call a separate ASPX page for my AJAX requests?
I have been struggling with this now for about two weeks, Within my site that functions as a directory, there are some simple Categories that appear to the user ashttp://www.mysite.com/subcat.aspx?catid=1 in the browser address bar.

I have to show progress bar in datalist and having following scenario:
I am collecting response for the questions For each answer, total no of responses and their respective Percentage(%) is calculated
Now I have to show this % progress in progress bar
means if a answer have 100% response then progress bar show 100% (100% filled) if it have 50% response then only half of progress bar is filled (50% filled)and so on. response is calculated upto one decimal places(like it can be 33.3% or whatever)and respective % have to be shown in progress bar
So I have to create progress bar dynamically for each response %
How to display % in progress bar, I am using asp.net 2.0 with C#..
I need to build a form that shows data is the following format:
M(1 Nov), T(4 Nov), S(7 Nov) etc user 1 yes/no yes/no yes/no yes/no user 2 yes/no yes/no yes/no yes/no
The yes/no will be represented by a check box and there will be Monday, Thursday and Sunday columns for each occurrence within the month - dynamically worked out. I was planning on using Anonymous Type's as explained here to represent the data. Is this a sound approach? My problem is how to display this using a GridView or DataList control. If the data structure is dynamic, how can I configure the GridView/DataList control to bind to the data?
