C# - Hide/Show Panels Inside The Repeater Item Template Using JavaScript?
Nov 29, 2010
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'm displaying summary and details customer info in each repeater row - inside the repeater .
The summary stuff is it's own div: (id="divHistory_Summary). The details stuff in it's own div:
(id="divHistory_details" )
The details div is hidden by default with inline style: display: none;
[code]....
I don't have the jquery.js file in the head of my app, so I hope it's ok to call the script right here. This app has many nested master pages, and didn't know which one to put the call to jquery file.
The page loads, repeater populates, the details stuff is hidden. When clicking the summary div, nothing happens - the details stuff won't show.
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 two asp.net buttons inside a template (Expand and Collapse) I want to implement a simple client side javascript function to hide the expand button after press it and show the collapse button and vice versa.
I tried OnClientClick event but I didn't know how to get the sender button and the second button from javascipt because they're in a template and their IDs will be generated.
I tried also to change their visibility from the code behind in the server (by Visible property) but the problems is the event handler will be fired after the postback and the changes will not be applied in the client.
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.

i'm using a repeater with an hyperlink and i'm displaying some data from a table x and when the link is clicked i want to add some from the displayed data in another table y..I used a datasource for selecting information , should i use another datasource for the insert command or what to do ..
I wish to add a sub to vb file that changes the display value of several asp:panels located in a Formview Item Template. My only question is what is the proper event to run this in. (databound, item created etc...) If it matters this formview appears in a Gridview Item Template.
I am using a repater whose item template is having a dropdownlist. Now i want to access that dropdownlist from a button click event. Here is the code iam using :
I am using aspnet menu control and i want to hide the item initially on page load and show the item after an event is trigger say button lick event Can any one give me an example?
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 have written a web usercontrol (ascx). Inside, there is a Panel that I want to show/hide on click of a hyperlink inside the usercontrol.
Normally, this is easy just by doing something like this (the onclick attribute is added to the hyperlink on prerender):
var PanelToShow = document.getElementById('<%=PanelInvoiceHasBeenCreated.ClientID %>'); if (PanelToHide != null) { PanelToHide.style.display = 'none'; }
but because the ascx control is held within the gridview, the above will assess all the controls (of which there are many in the gridview) with the name 'PanelInvoiceHasBeenCreated'. The only time it will work is when there is 1 row in the gridview. Currently, with my existing code, if I click the hyperlink in any row, it shows/hides the panel in the bottom row of the gridview!
Therefore, my question is how do I get the actual, unique ID I need to show/hide on the correct control in the correct row?
Here is a perplexing issue I have not seen a good answer to on StackOverflow, although there a couple stabs at it... I have a situation where I'd like to do this:
<asp:Repeater ID="MyRepeater" runat="server" OnItemDataBound="MyRepeater_ItemDataBound"> <ItemTemplate> <li id="id?"> All the other stuff </li> </ItemTemplate> </asp:Repeater>
is how do I get the ID of my <li> elements to be id1, id2, id3, etc., based on the ItemIndex they are bound to? So far the most... er..."elegant" solution I've come up with is to replace the <li> with an asp:Literal and dump the <li...>' text. But that just feels... so wrong. And no, I'm not using ASP.NET 4.0, which I've read will provide this functionality.
I know how to use a simple If statement wrapped in the <%# tags to hide something, but I don't know how to do it in a repeater when I need to access Container.DataItem, as in I need the dataItem currently being 'repeated'
eg
if (CurrentValidationMessage.Link != "") { show a hyperlink } Markup: <asp:Repeater ID="repValidationResults" runat="server"> <HeaderTemplate> </HeaderTemplate> <ItemTemplate> <a href='<%# ((MttImportValidationMessage)Container.DataItem).EditLink %>'> Link to erroneous Milestone </a> <%# ((MttImportValidationMessage)Container.DataItem).Message %> <br /> </ItemTemplate> </asp: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 have a gridview that I want to show a dropdownlist (for, let's say, column1) when it has a certain value, and I want to change that same column into a label when it has a certain value. Is this possible with gridview? if so, how?
I am using VS2008.I am binding dynamic datatable to gridview. I have few dropdowns and textboxes in gridview. I have dropdownlist(ddlTrCodeNw_)in gridview foooter template. Based on the selection of Trcode value few controls will be enabled,disabled,visible,hide. in gridview.
<asp:GridView ID="gvAPPost" runat="server" Width="100%" ShowFooter="true" AllowPaging="true" AutoGenerateColumns="false" onrowcommand="gvAPPost_RowCommand" onrowdatabound="gvAPPost_RowDataBound" > <Columns> <asp:TemplateField HeaderText="Discount %" Visible="false"> <FooterTemplate> <asp:TextBox ID="txtDiscountPerNw" runat="server" Width="40px" Enabled="false" Visible="false" ></asp:TextBox > </FooterTemplate> <ItemTemplate> <asp:TextBox ID="txtDiscountPer" runat="server" Width="40px" Enabled="false" Visible="false"></asp:TextBox > </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> Intially I set TemplateField HeaderText also Visible="false". so i have written the condition in ddlTrCodeNw_SelectedIndexChanged. Now when if(ddlTrCodeNw.SelectedValue=="24") { txtDepstNw.Enabled = true; txtDepstIncNw.Enabled = true; txtCrdtNw.Enabled = false; txtCrdtIncNw.Enabled = false; lblDiscTrcodeNw.Visible = true; // I want to show this TemplateField HeaderText also when i need. }
I can I show TemplateField HeaderText also whenever i need.
I am trying to get the index of the DataItem from the DataTable and insert that into the repeater. I tried this solution: [URL] but that does not give me what I want. that solution only gives me the location of the item within the Repeater, but I want the location of the item within its source DataTable. The reason for this is because I want to number my search results, and if I use the above solution then the numbers reset on pagination.
I am trying to inject inside repeaters items, the problem is that the row is generated in a wrong location. If you try this simple example, you will see that the rown is generated under label '2' as it should be generated under label '1'. Why does it happen? And how to fix that?
I have an aspx form containing many individual controls like and one repeater control. The repeater control items are basically having dropdowns, textboxes etc. next to each other. My problem is I can set the tab index of each individual element easily but I don't know how to set the tab index of the first element in of the first repeater item. That is why first I need to click the item and then the Tab index inside the repeater control works fine. Do you know how can I fix this? Should I handle this on the server side? or jQuery etc?
