Forms Data Controls :: Databinding To Standard Web Server Controls?
Nov 29, 2010
I want to create a form that will update an existing database record based on a querystring value passed to the page say UserId.
Rather then using data-bound controls such as the FormView, DetailsView, etc, I would like to use textbox controls, a dropdownlist and a checkboxlist to accomplish this alone. Is this possible? How do I go about binding the data from the database to these controls when the page is loaded and what data source should I create?
I have created my database in SQL Server 2005 Enterprise Edition and now planning to tranfer this databse to another server, But this other server is SQL Server Standard Edition, So if i try to attach my database which is created in Enterprise Edition will get sucesully connected to Standard Version ? or i will get any error message or i am doing something wrong ? This situation is fine or Version should be kept same ?
I have SQL Server Standard 2008 installed on my machine, alongside Visual Studio 2008.
My current hosting provider (not a huge fan) requires me to access my db's remotely via SQL Server Management Utility. To date, I've been doing it by connecting remotely in VS2008. Their troubleshooting documentation/steps, though, are for the SQL Server Management Express 2008, and i'm having a lot of connectivity issues with them.
I followed the steps here: [URL] to "add additional features to an existing installation" - but when I did so, the setup wizard indicated that the Management Tools-Basic were already installed.
I need to add multiple gridviews to a page displaying different data but of the same structure - the data has a lot of columns and I need it formatting quite tightly - is there a way of creating a template gridview in design mode and then somehow using that however many time I need to in the page as a template.
I do have the following code for for a GridViewd that display pictures that are stored in a file. I am using AutoNumber(GUID) from the database to name the pictures before I stored them to the file. I can save up to 4 pictures using the same AutoNumber but adding these ending to it, Pic1, Pic2, Pic3 ,,,,etc.
The problem that I am having is that after I get the AutoNumber from the database, I want to display a standard picture on the GridView field if there is not particular picture associiated to this record in file. The name of the standard picture is located in the same file under the name of NoPicture.gif. How can I do this? So far this is my GridView code and it is working fine:
I have a gridview in which I have two drop downs. One is populated with values that are static, so I have a regular sub that does that in the code behind. I tried to add code for databinding the other ddl to a datatable. I cannot get this to work. It just comes up empty. My asp code is fine, and the datatable definately has data in it - just nothing gets populated.
One other thing - the code for the static ddl has worked fine, but when I add this other block (either to the same sub as that, or dow the rowdatabound event) the static one doesn't work either.
Inside my repeater I'm calling an extension method like so:
[Code]....
he above is giving me an "Object not set to an instance of a object" exception inside the extension method. If I comment the above expression out, it works fine, and the items are binded wtih no problems.
im trying to use dynamic object in a databinding tag , it gives me error that the property does not exists even though i can see all the properties there in the vs debug mode
here is what im trying to do:
C#:
my method signature:
public static dynamic MyMethod()
ASPX:
in control itemtemplate:
<%# MyMethod().SomeProperty %>
if also trite the other way:
C#:
public static object MyMethod()
ASPX:
<%# ((dymanic)MyMethod() ).SomeProperty%>
But i dont know why it cant resolve the properties , even though i can see them when the databinder control throws an exception (its working fine outside the databinder tag (ie normal aspx tags <% %>)
I have a GV & a FV both linked to same sqldatasource.
When a GV row is clicked, the FV becomes available for editing the row but the GV as a result is reduced to only that row. I want to GV to remain showing all rows. I am using GV selected_index event to invoke "SqlDataSource1.SelectCommand=
I've created a templated user control by following the example on the microsoft support pages. I won't post it all but the important part of the CS file looks as follows:
[Code]....
I'm not sure if the whole _CurrentDataItem business is required, I don't think so.The problem I've got, is that I've tried nesting it inside a FormView control so I can use it to display a record from a database. My ASPX looks like this:
[Code]....
Now, the bound properties (TitleText and TitleSubText) bind correctly, but the nested / template content is blank when the page loads. I'm not sure if this is something to do with the order in which everything is loaded or because I'm missing some code in the SimpleTemplate to get it to bind (etc.).
I have a forms view with an EditItemTemplate. I would like to populate the EditItemTemplate using the code behind vs. mixing the data in the UI as so:
text='<%#Bind("Question") %>'
At what point do I do this? I thought it would be on FormView_DataBinding, but there is no e.item.dataitem like other databound controls. My issue is that I need to check criteria of the data prior so I know which inputs to make visible, to set properties of controls within the EditItemTemplate, and manipulate the data prior to binding (less of an issue as I can always just tweak the data prior to binding, but it doesn't solve my other problems).
I am having issues with databinding a textbox within a tab within a gridview. The textbox displays the data information properly; however when I try to edit a row in my gridview anything I type within that textbox is not saved in the database. Also my other fields for my gridview are editable, I am only having issues with this textbox within a tab. Here is the code:
I have a custom DataControlField class that works fine but when I try to use <%# Eval('???') %> with it I get an error."Databinding expressions are only supported on objects that have a DataBinding event. SharedG.ImageLinkButtonField does not have a DataBinding event."I can't get this to work,the DataControlField dosen't seem to have a DataBinding event to override or anything.I could use a normal templatefield itemtemplate etc.with eval but I don't want to rewrite this all the time. [Code]....
I was wondering what would be the best pratice to databind a gridview programmatically.Normally i put my databind code in the page_load() but is there a way to reduce the number of times the databind method is called?I mean... the page_load() method seem to be called a lots of times when doing callbacks with the grid.
I am trying to create a Gridview in which I can update the Project Officer name in the Gridview from a DropDownList.
The Project Officer DDL comes from a seperate query (SqlProjectOfficerName) as the other information (SqlDataSource1)... as you can see below.
When I select EDIT, the DDL appears and I can select from the list of Project Officers, but when I select UPDATE, the name of the Project Officer doesnot change.
review the code below and assist as appropriate to write the Project Officer's name back to the table.
I have a very simple form that contains a FormView Control Bound with a SqlDataSource, The DefaultMode of the FormView control is "Insert". I noticed that when I run the page for the first time, the databinsing and databound events of the FormView Control occurs after the PreRender Event of the page ! I know very well the life cycle of a page, but I dont know when the data binding occurs in the life cycle of a page and if it can differ from a control to another.
Is there an article or a tutorial explaining all those things.
i have an Gridview with BoundFiled, for the bound field headertext alo coming from the table, but i dont know how to bind the headertext and data. i have used below code
My problem is that I have a different format table for each section in my form. And I would like to bind data to these tables. A repeater I don't think is going to work. It would be great if I can do it like this:
[Code]....
Where the "+ 1" is the next record from that datasource --which is bound in code behind. Is there anyway, I can accomplish this without resorting to dynamically created tables.
I have a asp:repeater control which I am using to display a photo and the Name. So for this I have to execute SQL query and unfortunately I dont have the control of the database - table design. So the photo comes from one table and the Name comes from another table. I wrote 2 sql queries to get both these information created 2 sqldatareader. So now I have to bind the repeater control to both of these reader. But I know it does not work. Is there any other way I can do this? I even tried to nest a repeater control inside another. But that does not work anyway.
