Web Forms :: Possible To DataBind A Controls ID?
Apr 29, 2010
I have been attempting to Databind a control's ID inside of a datalist all day.
Does anyone know if that is possible?
I need to databind a LinkButton's ID, but have run into this error:
<dx:ASPxHyperLink ID='<%#Eval("name") %>' runat="server" Text='<%#Eval("Text") %>' />
Parser Error Message:
The ID property of a control can only be set using the ID attribute in the tag and a simple value. Example: <asp:Button runat="server" id="Button1" />
I can use any html control that will allow me to display databound text and databound ID

i'm opening a new window and passing on to it variables in a querystring, the values are loaded into a function that is filling my dataset and then filling my Gridview. after i press the button field in my grid to delete an item, the databind doesn't show the updated grid but remains the same. i've noticed that if i navigate back and refresh i see it correctly. in FF btw no problem.
the code:
this is used to open the new window

I hava a Gridview connected to an objectDataSource. I only want the gridview to databind when a button is clicked. My problem is that the gridview-ObjectDatasource databinds everytime the page does a postback.

I have worked a lot with gridviews, etc, but I am relatively new to Repeaters and I have a page that uses a Repeater to display records from a SQL Database. By default the date in the SQL field is 01/01/1900. I need to format the dateSHAWSTART & dateSHAWEND in my repeater so that if the date is 01/01/1900 that the fields should be blank. Here is my VB Code Behind:

Has anyone been succesfull databing the InsertTemplate of a ListView to an SQL datasource?
My ListView is databound to a SQLDataSource however the InsertTemplate needs to be initialized to the last entry/record on the database
So I can create a second datasource to grab the last record from the database but how do I bind it to the InsertTemplate?

How do you databind from an AccessDataSource to a Label Control on page_load? I know you can use eval, but how do you associate your eval statement with the correct data source control?

I am not sure if I'm in the right forum but I try anyway.I am making a webproject where I have a database with tables Product, ProductDetails.In my pageLoad event I am retrieving the information from these tabels in two lists: productList and productDetailsList.
Now what I would like to do is to databind these lists in code behind to my ListView. I know how to do this if I only have one list but in my case i have two and in my listView i have fields whose information is in productList list and others in the productDetails list.
Is there a way to achieve this?
Here is some code where I am databinding one List to ListView:

I'm working on a project where I have to create a page that displays the "health" of a system. I run a query and display the results in a gridview with a red or green icon next to it. This works fine when the page is first loaded. My problem is that I have a thread that runs a query every 30 minutes and rebinds the gridview but the gridview never refreshes even though the data has changed. How do I get the gridview to display the new results? The databound event never fires a second time even though I can clearly see that I have received new data. I assume I am missing something simple but I just don't know what. What am I doing wrong?

I'm trying to bind an array to a radiobuttonlist following the example from this link: [URL] The main difference is that I am creating my array from a database... the array seems to be populated just fine, I can create a label from any cell of the array, but I just can't make a radio button list from the array.
[Code]....
I get the error on the last line there and can't figure out why. EDIT: fixed the pasted code.

So I have a GridView and several events that can be triggered (such as filtering and inserting a new record) to manipulate the GridView. I want to make sure that I'm not calling DataBind on Page_Load, especially since I might have to call it again when certain events fire. Is there a way I can make it so I only have to call DataBind once on the GridView after Page_Load and anything else has fired? Like some event that will absolutely fire last where I can put my DataBind?
The reason I need to do this is because the DataSource for the GridView is set programmatically from a DataView when the page is loaded, so DataBind needs to run every time. Just, hopefully, not multiple times each time...

I have a gridview positioning issue that may have been answered elsewhere, but I couldn't seem to find a similar post...
I have a webforms app containing a paged gridview (e.g., 200 records - 50 rows and 4 pages).
When the user clicks on a button in a specific row, another web page is launched to process that button click. When the user closes that page to return to the main gridview, the databind event is rerun and the page redisplays the gridview starting at the top. However, I want to have the previous position maintained (like an html bookmark), so that the grid will automatically be scrolled to the the previously clicked gridview page and item.
Setting attributes such as "MaintainScrollPositionOnPostback" do nothing in this case.

My data-binding problem is this: I have a user control that contains a DataList, withing the user control I have an array of objects that are binded to the data list. This works fine and the datalist displays exactly what I want. I have also set up an event that changes the background color of one of the controls on a click. So when the click event happens through a bubble event I change the controls backcolor and then try to call the DataList.DataBind(). This does not work when all the controls Page_Load happens my binded object from the Array is now null. All the examples I have found in code that seem to work have you recreating the data source before calling the DataBind function in the PostBackEvent asp.net step. I don't understand why this is or how I'm suppose to resolve my situation since my datasource in my user control can't easily be recreated. I hope I explained this well I have included a test program that sort of duplicates the issue I'm having. If you run this code you will not get the data list to display at all on a click event. But if you call the BindList function it will work correctly.

I am have a page with a couple of dropdowns which serve as criteria for a select SPROC. Once a selection is made in a drop down a panel is shown which contains gridview whose rows have been returned by the select SPROC.If you close the panel and change the drop down selection and then redsplay your panel the data from your prior selection is still displayed in the gridview,
unless you page to the next group of records.

Getting the following sql timeout on a page System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
GridView1.DataBind();
While I know I need to review the actual Stored Procedure used, can someone point me to a quick fix to increase the timeout on the databind.
Below is my datasource

I have a repeater which does quite expensive processing when it is populated. It gets the info from a web service which is itself a federated search service and will take 15 to 20 seconds to return results.
In each repeater item/alternatingitem, i have 3 imagebuttons doing some actions (saving in session some ID's, updating some custom collections...) , the problem is when clicking on one of the buttons, the repeater will trigger the command and then databind again, which takes quite some time to process again..

I have spent most of my time writing ASP.Net web pages, using VS 2005. I am now developing some client function for Windows, so I'm relatively less expert in VB.In my Windows program I have defined a DataGridView and linked this to a data table (within a tableadaptor). Now I want to populate it: on a web page's code-behind I would write Gridview.databind(). What is the equivalent with a DataGridView.

I've this table Table1(ID , LinkURL , LinkText )
I would like LinkText to display as a link. And when you click it takes the value from LinkURL and directs you to another page.
This is the code:
<asp:GridView id="GridView1" runat="server"></asp:GridView>
And this is the code-behind:
