Forms Data Controls :: Show / Hide A Div In A Nested Repeater By Clicking On A Button Inside Parent Repeater?
Nov 12, 2010
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.
the output I am getting at the moment, is my parent data displays along with my child data. However when I click on the button to toggle the views i am getting a "cannot cast type error"I have also tried to put the itemdatabound event in my parent repeater tag, that worked but when I click on the buttons it just keeps moving to the top of the page and won't hide or show any of the child data except for the first child of the first parent.
<%@Page Language="VB" EnableEventValidation="false"%> <%@Import Namespace="System.Data" %> <%@Import Namespace="System.Data.OleDb" %> <script runat="server"> Dim ds As DataSet, divdtls, btnview, repeat Sub ItemDataBound [code]...
I am using a repeater to build a custom table. However, I can't figure out how to make the table show subtotal if the next rows tour does not match the previous rows.
Something similar to that.
row1 tour1 row2 tour 1 tour1 subtotal row3 tour2 row4 tour2 subtotal total
[code].....
but this shows all the data in the nested repeater not the ones that match the parentrepeater fields for example tour,theme,dep7 should match in the child repeater
I have set up an asp repeater to go through and display a list of people based on input parameters. Within that repeater I have a repeater that displays specific details about each person. No problem so far.
However, my requirement is that I only display the names, with a plus/minus sign to the left of the name. Clicking on the plus sign will expand that person's information to show the details. Clicking the minus sign will collapse the detail info.
I have a panel set up within my primary repeater that encompasses the secondary repeater.
I am using a repeater control and i want to use one more repeater control inside the existing repeater control .
Like this:
<asp:Repeater ID="Repeater1" runat="server"> <HeaderTemplate> </HeaderTemplate> <ItemTemplate> <!-- start child repeater --> Here I want to use one repater control <!-- end child repeater --> </ItemTemplate> </asp:Repeater>
I'm having a problem trying to retrieve a dropdownlist value that is located within a nested repeater. Basically I'm trying to create a shopping cart that allows the user to select a shipping method and the shipping method is contained in the repeater. So my page structure looks something like this.
Gridview
[Code]....
To me this should work, but the problem I'm facing is that there are no repeater items. The Items.Count property in the repeater is 0. I am not calling DataBind on the Gridview nor the Repeater before this code is reached (this code is the first thing that happens in my button click event) and my binding is done inside a !IsPostBack statement in my page load. I've made sure databinding is not occurring by setting breakpoints on the code that databinds both the gridview and repeater.
It seems to me like the nested repeater is losing it's viewstate or something on a postback. If that's the case, how can I get the selected value of that dropdown control inside a nested repeater?
I'm trying to hide a row in my repeater footer like so:
[Code]....
When it tries to hide the row i'm getting 'System.NullReferenceException: Object reference not set to an instance of an object.' Does anybody know how I can get araound this?
I added a (Read More...) Div to my repeater's item template, that doesn't contain any information.
I want to add a text button or an anchor to my item template..when it's clicked it should call a javascript method that writes information to the Div and it will take the content to write as a parameter, the content will be passed as an Eval method, for example it will eval("education")...and when it's clicked again it will hide the Div
I tried various and near approaches but it all worked outside the repeater and item template tags, but if I placed the identical code to the repeater and my javascript to the head tag it won't function!
I don't want to post my code, because I'm sure it's an easy and essential trick for any developer...so I was hoping for an original example not an edit to my test code(beginners logic)
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 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. :
[code]....
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.
