Forms Data Controls :: How To Dyamically Bind ObjectDataSource To New Datasource
Sep 23, 2010
Before i talk about my situation or problem let me tell you all that i'm new to ObjectDataSource, ListView.
i've following controls
Three LinkButtonOne ObjectDataSource Control (which is binded to custom Business object) . Paging is enabledListView (This is binded with ObjectDataSource Control)
Requirements:
By default ObjectDataSource should be bounded to DataSource A, thus the user should see on page load the default data from DataSource A.When user Clicks on respective LinkButton, the ObjectDataSource should now be binded to new DataSource B, thus the user should now see data in ListView from DataSource B. The same should happen with LinkButton C respecctively
I've created a query in the table adapter for retrieving customer name based on the first letter. The query is executed fine, and the output is the customer name and ID. A Customer BLL accesses this query, and sends the results to an objectdatasource. This control is configured to use this customer-by-letter query. However for some reason, this objectdatasource does not bind the name and ID, but instead all the other fields produced by the main query in the table adapter (i.e. name, address, phone, etc....).
I'm probably not configuring something correctly, but I'm not sure what.
I am using objectdatasource to bind datagrid,i m using select method of objectdatasource and manage paging (page size 10) and command event also,i have define MaximumRowsParameterName and StartRowIndexParameterName but now problem is when i am trying to delete 11th record from second page and again bind same grid than i coudn't fine rest of 10 records and get no records found.
I successfully bind ListView DataSourceID to ObjectDataSource but it binds only initially on Page_Load event. When I want to bind another data through a Button_Click event, the new data doesn't bind.
aspx code:
[Code]....
Codebehind:
[Code]....
On Page_Load, I get result:
A1 <hr /> T1 A2 <hr /> T2 A3 <hr /> T3
When I Button1_Click, nothing happens, no error, no any more results and _airLineData is 53 records, not 3 records (A1T1 to A3T3) I want the binding to be with DataSourceID to ObjectDataSource (not through DataSource property and control.DataBind() method)
I have an ObjectDataSource with a number of parameters. These parameters are binded in my FormView EditItemTemplate and the ItemTemplate. My Stored Procedure column names in my ItemTemplate are different to the Bind properties used in the EditItemTemplate. This is obviously throwing an exception when I update a record.
Instead of using Bind("Columne Name") in my EditItemTemplate how do I use a ControlParameter to reference a TextBox in the EditItemTemplate?
I may be wrong but I'm trying to use the PropertyName=Controls but i do not know how to reference the Textbox in the EditItemTemplate.
Created button in the rowdatabound event grid show the button fine, but on clicking it dont fire the delete button event :(. How to resolve it. Rows and columns of grid are created dynamically.
Button btnDelete = new Button(); btnDelete.Text = "X"; btnDelete.EnableViewState = true; btnDelete.Command += new CommandEventHandler(btnDelete_Command);//Add this to every cell. e.Row.Cells[4].Controls.Add(btnDelete); void btnDelete_Command(object sender, CommandEventArgs e) Response.Write(e.CommandArgument); }
I have connected listview by using datasourceid that means by using "sqldatasource1" now i want to change value of listview at run time according to search so for that i am using datasource at codebehind. but it give an error
"listview have already bind with datasourceid you can not bind it with datasource"
I have a webpage that uses a formview. The formview gets the data from the objectdatasource which connects to a query in a table adapter.
I wanted to add a hyperlink in the page right below the formview that will "hyperlink" to another page passing parameters. Those parameters are values from the formview.
Can I just access the parameters of objectdatasource from outside the formview as follows?(it isn't working)?:
<asp:HyperLink ID="HyperLink215" NavigateUrl='<%# Eval("VIN", "Contact.aspx?Subject={0}") %>' runat="server">Contact Us Regarding This Vehicle</asp:HyperLink>
If not, can I access those parameters in codebehind and do a redirect from there? How do I access the data of objectdatasource from codebehind? If I can do that, I could just put a button. Then in the button's click even, I could do the redirect.
I am trying to bind a DataTable into a ObjectDataSource. This ObjectDataSource data will be used to bind into my LocalReport in ReportViewer. I have already successfully binded my data into the DataTable. My problem now is how do i bind the data in my DataTable into the ObjectDataSource so that it can be used in my report?

I have this list of names where I want the location underneath each name but nothing is showing up. Is it not actually possible to bind the repeater's datasource to the items in the datalist because nothing is really selected in the datalist - it's just all there?
i would like to sort a listview. i don't have a datasourceID. i bind the datasource manually. i think of using jquery(tablesorter) but i don't know how to use it.
I have the following structure 3 Dropdown Boxes, the 2nd and 3rd dependant on the 1st and when I change the first combo the pages refreshes with error I am assuming it's happening when posting back. I have nothing in my code behind file for this page so far.
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
This is a very Basic application that I am creating using Visual Basic and ASP.Net 3.5. Am using a SQL Datasource have searched for this error some of the answers seem extremely complex and I can't figure them out, surely a simple tasks like this has to be easy to bind back to the database from several drop down lists.

I am really having a hard time trying to write something from scratch I created a 'Person' Class.Public Class Person

I am trying to select data with Linq and bind to a DDL. The custid field allows duplicates in this table, but I only want unique values in the ddl. I tried the following code:
[Code]....
The use of "Select Customer.CustID", with or without the Distinct, causes this runtime error. CustID is a valid field in the table, and it shows up in intellinsense and compiles. If I just Select Customer, the error goes away, but Distinct doesn't know to look for distinct custid's.
DataBinding: 'System.String' does not contain a property with the name 'CustID'.
Im working on app that queries another website, and pulls back an xml, I then populate a result panel with ImageButton(s), and time in a click event, when the image is click I want to popup a div box using the jquery ui, that will show more information, about the picture clicked on. however whenever id this this seems to wipe out my results panel(Panel Control) and the div box never appears and as far as I can tell the imagebutton click event never fires. I've tried doing this two ways one with an update panel and again without, I would appreciate any help on this.Im wondering if I'm doing to much long on my search button click, Im wonder if I should just let the post pack handle populating the result panel and ditch the update panel.(and yes my div tag is set to runat server)I'm also up for suggestions maybe there is a better way to do this, I thought creating hidden div tags for each item, and then running javascript for when the image is clicked and showing it that way, However that seems stupid, in my opinion it seems to make more sense to make my div control once and then update the labels inside it on each image click and then show or hide it.
I have a button, which when presses populates a grid with data. If I add an ObjectDataSource, and bind the grid to it, it will populate the grid when the page loads. But I need to populate the grid only if the button is pressed, because it is a lengthy operation.
