In the code behind I have a function that returns a List(Of SomeClass):
rptRepeater.DataSource = SomeFunction(SomeVariable)
rptRepeater.DataBind()
<%#Databinder.Eval(Container.DataItem, "Parameter1")%>
I have to set a LinkButton's OnClientClick attribute but I don't know what this value is until the LinkButton is bound to. I'm trying to set the value when the repeater binds, but I can't workout how to get the 'boundItem/dataContext' value.
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<asp:LinkButton Text="HelloWorld" ID="Hyper1" runat="server" OnDataBinding="Repeater1_DataBinding" >
</asp:LinkButton>
</ItemTemplate>
</asp:Repeater>
protected void Page_Load(object sender, EventArgs e)
{
var list = new List<TestObject>();
list.Add(new TestObject() {TestValue = "testing1"});
list.Add(new TestObject() { TestValue = "testing2" });
list.Add(new TestObject() { TestValue = "testing3" });
this.Repeater1.DataSource = list;
this.Repeater1.DataBind();
}
public void Repeater1_DataBinding(object sender, EventArgs e)
{
var link = sender as HyperLink;
//link.DataItem ???
}
Is there anyway to find out what the current rows bound item is?
I have an ASP.NET page that has a code-behind method that is defined as follows:
[code]....
Essentially, when the TicketStatusID is bound, I want to call back to GetStatusColor and display the result of the method instead of the actual ID. How do I do this in a Repeater?
I had a web application that was binding a IDataReader to a repeater control. I converted the project from 3.5(2.0) to 4.0 and then I received the error:
An invalid data source is being used for rptData. A valid data source must implement either IListSource or IEnumerable.
So, I used a datatable instead and the binding worked. So it seems that they have removed this functionality with .NET 4.0.
I have what's bound to be a stupid question, so I'll apologize for what I think should be an obvious answer my brain just can't see. My problem is very simple. I have a Repeater control bound to a SqlDataSource. The ItemTemplate in this case is one complicated beast, and rendering can take a loong time if too many records are returned; so I need to maintain tight control over how many records are brought back from the data source.
Is there not some way of either stopping the creation of subsequent RepeaterItems once a certain count has been reached, or cancelling the bind if more than a certain number of records are returned? I know I can grab the record count from the AffectedRows property in the Selected event of the DataSource, but I've encountered a brain-lock on how to stop/inhibit the binding (or RepeaterItem creation beyond x records).
I'm happy with either aborting the binding altogether if the record count is too high (displaying no records), or simply stopping it after X records are returned; at this point, I'm not picky. Either way would work, and it seems I ought to be able to readily figure out either one, but my brain has simply gone into neutral.
I have a GridView with an image button in a TemplateField in the last column.
I would like to pass the GridView row values (Bound Field Values - a record) to a JavaScript function to create another html table of selected records in ClientSide (like jCart-A shopping cart).
I would like to know how to pass all GridView column values to the javascript when the image at the end of the respective row is clicked.
how can i use cursor in this function ?
ALTER FUNCTION [dbo].[GetCatIDChilds]

@CatID [code].....
My GridView is bound to a certain DataSource. Each row only shows 4 of the 8 possible items. Lets say we have name, adress, phone, fax, email, country, province and age. The GridView would only show name, email, country and age, but I want to access the province and adress bound to a row.
I got a custom GridView, with an onclick event which updates an panel (through AJAX) which shows additional information about the selected row.
i think this maybe an easy one...I have a Gridview, bound to a dataSource with this query:select userid, name, phone from usersI need to change the content of the Name cell to a link, like so:<a href="http://www.domain.com/page.aspx?userid=12345">User's Name</a>
so OnRowDataBound i'm doing this:
e.Row.Cells[1].Text = "<a href="http://www.domain.com/page.aspx?userid=" + e.Row.Cell[0].Text + "">" + e.Row.Cells[1].Text + "</a>";
It all works fine this way. My problem is that i don't want to display the UserId column in the Gridview, but when i attribute it (asp attribute or server-side) Visible="false" to the BoundField UserId, i can't capture it's value to build the Name Cell.
I have the following code that I wasnt to alter the Dataset before it is bound to the dropdown list.

I know the question has already been posted here but we didn't get to an real solution.I have bound my ListView to an SqlDataSource and I want to write some text in a control present in the view created in the LayoutTemplate depending on some properties of the rows returned.Obviously, I'm using the ItemDataBound event to feed my items but this is not the point.
The spontaneous solution was to bind the ListView.DataBound event and access the raw datasource (a DataTable?) and do the required calculations.I inspected the Items property and, despite it was not empty, the related DataItem property was null.The only work-around I can come to is to execute the calculations in the ItemDataBound event and accumulate the result in some private fields. But it's really ugly to see and makes harder to get some of the required values.
How do I bound a Label to a datasource and its field?I got set up the datasource to a gridview, but don't know how to bind a label to the same datasource.
View 8 RepliesI have a Gridview that displays some data I am pulling from a SQL Server database. The stored procedure that runs the query accepts a table valued parameter. I am unable to find a way to pass this structure to an asp:SQLDatasource so I have been manually creating the datatable and then binding my Gridview to it. The DataType I am using in the code-behind to pass into the stored procedure is a System.Data.SqlDbType.Structured type.
Each Gridview row has an asp:LinkButton with a CommandArgument value that looks like
<%# Eval("PartNumber").ToString() + "|" + Eval("ID").ToString() %>
Each LinkButton calls back to a function in my code behind that accepts the CommandArgs, does some work, and redirects the user to another page.
Since I am manually binding the Gridview to the Datasource when the number of records exceeds my paging size and the user changes pages or sorts the Gridview, the CommandArgument value changes to the wrong row and I get bad data back from the CommandArgument. how to pass a System.Data.SqlDbType.Structured type into an asp:SQLDataSource but if that is not possible how I can work around this?
I have a code behind page with two functions that return two counts (iCount and iCount2). In my repeater table I can display the results of the functions just fine, but now I need to do some conditional logic based on the results of the functions, eg:If iCount =>3 AND iCount2 =>1 Then
View 6 RepliesI have a GridView populated by an ObjectDataSource. I also have several DropDownLists filtering the ObjectDataSource. I found a link providing a way to export a DataSet (or DataTable) to Excel here:
http://msmvps.com/blogs/deborahk/archive/2009/07/23/writing-data-from-a-datatable-to-excel.aspx
ow I can ensure that filters applied to the ObjectDataSource when the method is called are applied. In short, how can I ensure what the UI is displaying is what the file will include when exported?
I've done things like
<%# somefunction("string") %>
before in my asp code, calling some public function in the codebehind. But now I'm trying to do this from within a repeater item. The message I receive from the compiler is: "The name 'somefunction' does not exist in the current context." Error 97 The name 'getclass' does not exist in the current context 169
I'm looking to write some script that checks that: The current user of whom is logged in has the correct authority credentials. NB: Script in C# before I continue. To give a bit more background. The SQL DB Table for AdminUsers has a field 'Authority' this is linked to another table (Authority) which has the values/different levels of authority in them. Thus, if aN admin user whose Authority level is just listed as 'user', for example, in the database and wants to edit information that requires 'Supeuser' authority level - it cannot be performed and is redirected to another page. In detail, my particular page, the operation is being done via a ASP Button within a ASP Repeater. Of each record that occurs there is the button that, once pressed, updates the field in the database (in this case for a Guestbook table which has a 'Moderated' field of 'bit/bool' data type, changing it from false to true (or 0/1)). To allow that entry to be displayed on the front-end for public viewing. All this can onyl happen on the basis of, as previously stated, their authority is of the appropriate level. Here is what my attempt was. The outcome of which simply redirects to the 'Unauthorised' page, despite the user logged in having the correct authority credentials.

I have a FormView bound to LinqDataSource, that is intended to allow editing of a single product's details, that is selected from a GridView. The LDS has a Where parameter set to point to the GridView control (i.e. a ControlParameter).
View 1 RepliesThis was a pretty disappointing moment - when databinding, using Eval("Contact.LastName") would work. It nicely evaluates the related Linq object's member LastName. If the "Contact" object is null, no error is thrown... instead the field is simply null.
However, the same does not hold for sorting - if there exists a null entry (this object does not have a Contact) then the LinqDataSource throws a NullReferenceException. This means that, if you ever have nulls on your foreign-key objects, you can't use sorting headers in the ListView.
This makes the feature moderately useless - I have to roll my own properties for every single field I'd ever want to sort on. That's insane.
I am collecting user roles into a single dimension string array.
I have a repeater that its source set to that array. The repeater template includes list of checkboxes for the values in the array.The checkbox text is set to: Text='<%# Container.DataItem %>'
All is good till this point.
But I am trying to call a javascript function triggered by clickign a checkbox and pass it the container.dataitem, but the javascript doesn't seem to be reading the value and either complain about string not being in correct format or that treats the container.dataitem as a liter. This is the trial that didn't work (I tried many different things too):
DetermineVal(<%# DataBinder.Eval(Container.DataItem) %>);
determineval is my javascript function
Can I do that with a single dimension array?

there is a statement like " select t.f1, (select ta.f2 from ta where t.fk1=ta.fk1) from t inner join ta on t.fk1=ta.fk1 "? In SQL 2005, this will get the message "The multi-part identifier "t.fk1" could not be bound.".beacuse the result will contains duplicate data from table ta in one row.
