Forms Data Controls :: Accessing Data Generated By A Repeater?
Apr 22, 2010
I have a repeater that dynamically generates the sum of integers upon a button click (a random number gets stored in an sql database). The sum works fine and I get the appropriate output, however I would like to grab the sum and put it back into my C# code so that I can perform operations with it (it's the accumalated score of a game of blackjack so want to check if they are bust etc.) Here is my code:
<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1" >
<ItemTemplate>
<label runat="server" > <%# DataBinder.Eval(Container.DataItem,"a") %> </label>
</ItemTemplate>
</asp:Repeater>
How do i grab the DataItem "a" and put it back into my code?

I have a gridview which has autogenerate Columns Property "TRUE", and i'm dynamically binding this gridview with columns with sql database dataset. there is no data in sql but i am successful in showing blank gridview on form, now i want textboxes in gridview attached with each column, so i wrote code in RowDataBound which generates textbox automatically and assigns ID to each textbox, nw i want to insert that data from textbox to database but i'm not getting text which is entered in those textboxes, as i am accessing that textboxes using findcontrol and passing the id like gridview1_ctl03_text0. but i''m not getting any value from textbox?
In short i want to access auto generated textbox (with out any id predefined ) values from footer of gridview

I have a user control that displays a shopping cart in an ecommerce application.
The main cart display is a repeater that renders as a html table. In one of those table columns, there is another repeater to display people associated with the products int he cart (it's a repeater in case there is a line item >1 with multiple people).
I've added an ImageButton that I want to use to change the person associated with the item. At first, when I'd click on it I was getting this error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
So as an experiment I disabled EventValidation on the page (not the control it's self) and now I do not get an error, but I also do not ever hit the breakpoint I set in the innermost repeater's ItemCommand event.
So I wonder how I might do this without disabling EventValidation, because this control will show up on multiple pages and we don't want to edit them all. Also, I'll need to know not only the repeater containing the control's row that the event came from but also the row index of the repeater containg this one. Is this possible?

I'm so confused I wasn't even sure what to make the title so that it would make sense.
Here is what I have:
[code]...
I have links at the top of the page that are the letters A-Z. What I want to do is click on one of the letters, then show only the div IDs that start with that letter. I can't figure out how to do this since I'm dynamically creating the ID names. I had it set up nicely with Javascript and CSS, but the function call was inside the repeater. The layout is changed now, and I don't understand how to make the div ID available outside the repeater.

what changed do I need to make to my code for it to achieve what I'm after.
At the moment I am getting a "cannot cast to type" error message with the below code.
I have also tried calling the ItemDataBound method in with the parent repeater tags and had no errors but when I clicked on the button it would just move back to the top of the page and would not hide or show any data. Also I have made the div style to none but the first record still shows its child but the rest don't.

I have a many to many table in my database called PeopleLanguage
PeopleId, pk and Languags pk each go to the own table People and Language
I know make a method call with my objectdatasource GetPeopleByLanguageId
This returns the languages that the selected person speaks and has a select
query also to lanaguageTable to get LanguageName.
I now print out the results in a datalist that is binding to LanguageName.
What i want to do is show the languages in a horizontal format with a comma after each one.
At the moment if there are 3 languages it shows each one on a seperate line / if I make it horizontal
layout I still dont get a comma. Perhaps I can use a repeater?

Am using datalist to create a kinsd of message board, in the back end am having two tables one for the parent comment , and other for the child comments
The data source is extracted by LINQ to SQL with the load option , so I get everthing when I debug on the code behind , and I can see all the fields each parent comment and the child comments.
the problem is with binding the data on the disply for example all the parent table fildes can be rendred without any problems:
<%# DataBinder.Eval(Container.DataItem, "comment1Parent") %>; "showing me the orginal post"
Problem here:
<%# DataBinder.Eval(Container.DataItem, "Childcomment") %> is not rendred and I got this error msg:
DataBinding: 'DataAccessLayer.Comment' does not contain a property with the name 'childComment'.
In the debug I navigate to the childComment and this is its HTML visualisar:
new System.Linq.SystemCore_EnumerableDebugView<DataAccessLayer.Comment>(((ASP.usercontrols_comments_ascx)this).Comments)).Items[0]._comments_Replies.entities.items[0].childComment
I tried
<%# DataBinder.Eval(Container.DataItem, "_comments_Replies.childcomment")
Same as above error came to me.

I have a repeater control bound to a dataset. Within that repeater I have several further controls one of which is a dropdownlist. I trap the OnSelectedIndexChanged event of that dropdownlist because I want to recalculate some figures presented on the same row within the repeater.
How do I reference other controls which are on the same row of the repeater as the dropdownlist ? Is there an index property or other mechanism whereby I can identify the "current" row?
