So as the footer is writing programmatically, I would like to hide the FooterTemplate for somebody who use the custom repeater.. I was thinking [PersistenceMode(PersistenceMode.InnerDefaultProperty)] will do that but apparently not..
I have a nested repeater which displays a food menu - e.g.
Sub Heading - Food 1 - Food 2 - Button 1
Another Heading - Food 1 - Food 2 - Button 2
etc. etc.
What I have is a series of buttons inside the itemtemplate of the parent repeater (button 1 and button 2) which, when clicked, i need to somehow add a new blank textbox to below food 2 in whichever section it is clicked
I am having trouble doing this. See my code snippet below:
[Code]....
When I run this though, I receive an error of "object reference not set to an instance of object..."
Do I need to actually find a control within the footertemplate itself?
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 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'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.
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?
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 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 repeater control having columns in it.When I bind the control to a data source then some of the columns become empty when there is no data associated with it.I want to hide the column if there is no data associated with it.I was trying to implement a solution given in this thread:
[URL]
However,I am not sure how to write the logic for hiding and showing the placeholder.I have written some code for the same but that clearly doesn't work.The following is the .aspx as well as the code behind which I am using:
I have a label in a footertemplate of a gridviewcolumn. I want to put a calculated value (total of the rowvalues) in this label in javascript. I can access all the textboxes in my Itemtemplates, but I don't know how to find my label in my foortertemplates.
- I have a GridView , I want add a row FooterTemplate to add a new record in GridView . But I want to validate TextBoxs in FooterTemplate. My language I using is C# , Web Form .
I am placing a dropdown list in the footer of a DataGrid like this:
[Code]....
In my code behind file, in the myDDL_OnLoad event handler, I call to the database, populate a SqlDataReader, and set the DDL's datasource to that datareader. I define what data columns should be used for the DataValueField and DataTextField of the dropdownlist. Then I call the DropDownList's DataBind() method. Everything works without error. But, when the dropdownlist is displayed, it has blank lines in it.
By that, I mean if 8 records are loaded into the dropdownlist, it will expand to a size appropriate for 8 rows but, it will be empty. there is no text in it.
Has anyone seen this type of behavior before? This dropdownlist is in the footer of a dynamically loaded ajax update panel so, it is difficult to see the source code to see what values are in the html element rendered to represent the dropdown.
I have two dropdowns in the footertemplate of my gridview inside a usercontrol.
I also have a button "btnADD" inside the footer template. I am using the footertemplate to add a new row to the grid.
What do I do to validate on Button_click event for 'btnAdd' if a value is selected in the dropdown other than "select.." which I dynamically add in rowdatabound event?
I have this javascript function that I wanted to implement, but it gets called in the Page_load event rather than the button click event and gives an error.
The javascript function that I need to call is this: ( I created a method to return a string to use it in regards to RegisterClientScriptBlock, but do not know exactly how to use it)
