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.
View 1 RepliesBefore 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 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.
I have a dropdownlist that's being populated from a SQL datasource. I would also like to have a tooltip for each dropdownlist list item on mouse over. I found the example below which adds a title attribute for each list item using the listitem text as a tooltip but I want to make the title/tooltip value another field in the database. In other words,
item.Attributes.Add("title", someotherdatabasefield);
The end result would be something like this where the text for 'title' comes from the database
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True">
<asp:ListItem Text="CompanyName1" Value="1" title="a really great company" />
<asp:ListItem Text="CompanyName2" Value="2" title="a really bad company" />
</asp:DropDownList>

I have been trying some things and got stuck in problem.
I created a Gridview and SQLDataSource in designer and a on Button event executed the following Code
GridView1.DataSourceId="SQLDataSource";
It worked Fine and populated the Grid View.
But when i Decided to PRogramatically Create SQLDataSource ANd populate the Gridview by the following code
SqlDataSource fd = new SqlDataSource();
fd.ConnectionString = "<%$ ConnectionStrings:ConnectionString %>";
fd.SelectCommand="select * from [Department]";
GridView1.DataSourceID = "fd";
it didnt work. And Gave the following Error
The DataSourceID of '' must be the ID of a control of type IDataSource...
i am facing a minor problem but can't find out its syntaxi have listview, and inside the template i have 2 labels, in design time i bind 1 label to one column thatis 'type' and depending upon this type i want to bind other labels to different columnsif type is question than 2 label will have to show data of question columnif type is job than 2 label will have to show data of job, so on........how to accomplish this,in databinding event handler i can check the value of typebut i want to know the syntax of binding 2 label in run time, with different fields using EVAL
View 3 RepliesI am using Visual Web Developer (VWD)and I dragged in i.e created a Gridview. In the codebehind of the page, I will like to declare an sqldatasource and get data from a database using the sqldatasource and then bind the sqldatasource to the Gridview. PS: I know how to drag-in an sqldatasource and attach it to the gridview using VWD but this time, I want to do this declaratively in the codebehind.
View 3 RepliesI am now trying to bind data from SqlDataSource into a textbox, but the problem that I face is that my DataSource only return a single row. So i don't place my textbox inside any DataView or listview.
Below is my datasource:

So can I possibly bind the data into the textbox?

View 1 RepliesI have downloaded the ajax control tool kit but i cant make the combobox display data from the db.
From what i read from online resources , it seems my syntax is correct...but data is not displayed!
Here some markup from my page
<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="asp" %>
<asp:ComboBox ID="Supplier" runat="server" style="margin-left: 57px; display: inline;"
Width="245px" DataSourceID="dsSuppliers" DataTextField="SupplierName"
DataValueField="ID" MaxLength="0" AutoCompleteMode="SuggestAppend"></asp:ComboBox>
<asp:SqlDataSource ID="dsSuppliers" runat="server"
ConnectionString="<%$ ConnectionStrings:unrafpl %>"
SelectCommand="SELECT [ID], [SupplierName] FROM [tblSuppliers]">
</asp:SqlDataSource>
how can i access the my sqldatasource selected datasource for modification and adding for example new datacolumns before binding??where is the best place to perform these modifications ?i guess SqlDataSource1_Selected is the right place, but i don't know how ?
View 1 RepliesI'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.

View 2 RepliesI 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.
View 1 RepliesI have a GridView, I bind it to ObjectDataSource. ObjectDataSource takes data from a database's table. Each row in table has unique ID.
I have a button in each row of GridView that should remove this row from database. My ObjectDataSource returns Object, this returned object contains ID (and some other information, like name, user etc.) however I do not show this ID on my grid.
how can I get these ID after user chooses to delete row, I need to know what I should remove.
i have a sqldatasource which will return 1 field (1 row) for an ID. I need to get that result and display it on a textbox. I would do it using a stored procedure (this was already made) but i was thinking sqldatasource is easier. Is there a way to bind that result onto my textbox?

I'm looking for the easiest way to bind data from a SqlDataSource to textboxes dropped in Visual Studio 2008.
For example, I have 4 textboxes currently that have Address, City, State, Zip. I also have a SqlDataSource on the page fetching the ID of the record and selecting those 4 fields based on ID.
How am I able to quickly bind each box to those particular fields selected? I would think this would be really straight forward - but seems it's not. Seems like the answer is funneled towards having to create a GridView or some type of control.
Should i use dataset in code behind or SqlDataSource on the form designer to fill or bind a DropDownList in my asp.net page I am currently using SqlDatasource on the form and i bind the control to MySqlDatasource because i find it is very easy and to much faster but somebody told me to use dataset from code behind because of security and performance
