Forms Data Controls :: Button Within Repeater Does Not Work?
Jan 19, 2010
I have a repeater, and within it I have a button that shows up for each data entry. I would like it so that when I click the button, a certain action takes place, however this does not work. When I click the button nothing happens at all (the page just refreshes), however as soon as I move the button outside of the repeater, it then works.I used to get this error when when I pressed the button:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration"
But I then disabled event validation...when I disabled it I didn't get the error anymore, but the button remained useless.
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 presentation to the CFO in two hours. I can't get a nested repeater control to work right, something to do with teh placement of the <table> tags I think.The first repeater first section works fine, then the child repeater shows the first child section right, but the next section of the parent repeater loses all the formatting applied at the parent table. I've tried vaious permutations of where to place the closing table tag of the outer and the inner and get different results, but never the right results.
when i am trying to use a repeater to display data in a wizard control, everything seems worked as expected before i change the value of wizard's DisplaySideBar, here is my demo code:Test.aspx:

Test.aspx.cs:

guys who intrest on this you can copy this code and test it on your pc, when we click the link button in repeater's item will do nothing at the first time but it will work when we click it again.i have debug this and found that when the page is not in post back, the linkbutton's id will be "MainWizard_rpMain_ctl01 _lbEdit" in prerender method but after render it will change to "MainWizard_rpMain_ctl04 _lbEdit", but when page have been post back, the clientid will be correct as "MainWizard_rpMain_ctl01_lbEdit" and then event can be fired correctly.i thought this is a bug of .net framework, when i set the value of wizard's DisplaySideBar, it will ask to re-create controls but repeater haven't clean the item's count and then recreate item will use wrong item index, i hope this message can be post to .net framework team and they can find out what's the matter on it.
I actually need a little help here I'm using LINQ and displaying some data through a Repeater, with everything working fine. The scenario is: for example, user "Daniel" has 2 songs; on my Linqdatasource I'm selecting "songName" (name of the file name to put it on my mediaplayer, to populate the mediaurl) and the "plainName" (the name which the user inserted as the name of the song). So I'm just gathering 2 strings. My .aspx code:
[Code]....
I have a LINQ Table "Vote" (userID, songID, vote -> float)... and I want to rate each song (at the moment there are 2 songs... and the limit will be 3 per user), via the button "rateSong"... I'm not expecting you to give me the code to perform the specific rating, but how will I get to the specific button event? Is it in the Repeater1_ItemCommand?
[Code]....
I've searched for a few posts on this forum, but none of them helped
I'm having some real problems trying to do this. In simple, a table shows a list of rooms with details of the room in each column, extracted from a database. The there is a button in the repeater, which is supposed to tell me what I clicked on in a new label. However the OnItemCommand just doesn't seem to be working.
[Code]....
Right now I'm just trying to get it to work, so that when I press the button, it causes the label to say "It works". But it just doesn't want to work.
I have a repeater that iterates over a datasource, and each detail of the datasource has a type of control or entry method, I have an enum to represent the type of control
[Code]....
And I have this in the repeater's ItemCreated event:

This is the aspx file:

The problem comes when ENTRY_METHOD.FLEXI_SELECT is selected, because this will maps into a gridview and it need to be able to add, insert or delete items inside the gridview. Every time that I add an CommandField button with ShowSelectButton in true, it makes a postback an reloads the items inside the whole repeater, not only the gridview. This behavior is correct? How can I do to add a repeater that has inside a gridview that has select button and does not fires the repeater's OnItemCreated?
i have a repeater that displays data from a SQL Server Database. I also want to display an int from the database for the specific item and allow the user to add 1 to the value of that int by clicking a button (almost like a pole). It would work similiar to a 'like' button on Facebook.e.g.
I want to present a list of delivery options to end users which will be in 3 columns - service description, radio button (to select) and then the price of the service. Also I want to auto postback when the user selects a service from the appropriate radio button - e.g. :

I have set this up using a repeater control and stand alone radio button, plus literals to display the text elements all within a tabular structure which looks OK. I have actually overcome the issue where by default you can select all radio buttons using the prescribed javascript fixes I found when searching. This way offers me control over the formatting which is important.
However it does not seem that intuitive to pickup the selected value of the radio button this way, especially with the auto postback - I am having issues trying to access the selected radio button to interpret what the user wants.
It would seem much more appropriate for a RadioButtonList but I can't work out how to override the default formatting, and also how to insert extra table columns for the price etc to keep it all nicely formatted.
So either I need to crack the interpretation of the current setup or to find out is there a way to hijack the default setup of the RadioButtonList?
I got this problem that I'm trying to repeat an imagebutton inside a repeater so I can add an command argument to it... But the image butten fails and I can at the most get it to write "Subit Querry" att the fields where I'm trying to get the images to appear. I havent that much usefull code for this after trashing the most in frustrations. but this is what I got.
[Code]....
So what I'm trying to do is put a Imagebutton around my <%#Eval ("img_name") %> so I can get the src from my DB.
I am using Repeater control. In DataBound event I am preparing output of item and everything works ok. But now I need to add a command button to item. I cannot add button to item template in designer (some project specifications do not allow it). I create new button at DataBound, set unique ID, command name and argument and bind it to command event and, thenm place it to Item controls container. It is not working as command button.
I've adde a WebUserControl inside Repeater control. My WebUserControl consists of basically three controls: a CheckBox, a HyperLink, and some Label control. Plz have a look:
[Code]....
I've some Buttons outside the Repeater control. Now I want to select individual row through CheckBox and process it on Button (outside Repeater) Click.
i have a repeater with a button in the footer template which i want to be able to update any of the items that are added (update quantites/totals/delete the item).
however the 'UpdateOrderDetails' event never fires when the button is clicked.
I have a simple GridView with AutoGenerateColumns,Edit and DeleteButton = true
It's data source is a DataTable dynamically generated.
Since i don't want to use object data source, i just catched Delete event and deleted rows from datatable and made a new databind. It works.
I tried to use also AutoGenerateEdit button, but when i click on Edit command field, nothing happes. So i decided to handle by myself edit events, and changed datagrid in this way:
