C# - Page Still Refreshes After Wrapping The Repeater In An Update Panel
Dec 2, 2010
I've two SqlDataSources and two Repeaters, each repeater contains one hyperlink (i also tried using web server button and anchors). The hyperlinks fetch from the database some values and in the NavigationUrl property I use a string.Format method to create a parameterized url, to pass for the browser, then second repeater is populated according to the value passed in the url which is originally passed by the first repeater's hyperlink. this is my sample code : [URL]
I have an update panel on my page. Within that is a repeater which has a user control in it. Inside the user control I allow an update to the datasource of the repeater. I am able to successfully save the data to the database but when I call the .Update method of the update panel, the user control is blank. If I proceed to refresh the page, the data appears with the changes I made. why the data is disappearing when I call the .Update method?
Instead of binding my generic List, I would like to bind my LINQ collection instead. Only problem here is that the generic nature of the LINQ object means that DataSource cannot check and display the properties defined in MyDataStructure. How can I bind my LINQ query output to myRepeater?
I've got my repeater generating a list of links that need to appear in a certain order. Meaning I need my list to appear like so
-Item1 -Item4 -Item2 -Item5 -Item3
Every solution I've found involves knowing whats going to be in your list and setting classes where the list should break. My issue is that it could be anywhere from 1 to 18 items. So my question is, is there a good, simple way to vertically wrap a list that's being dynamically generated using an ASP.NET repeater control?
I am querying the SQL database table and returning the result on the webform with a repeater, but I need to display one record at a time and refresh with an update panel and timer to iterate through the rows of the table one at a time at a fixed interval.
Is there another solution to be able to display one record at a time using c# in the webform, but then cycke through the other records one at a time using a timer control and updatepanel?
I have two update panels on my page. One of them contains a list of users which is retrieved from the database. When I click a search button (which is outside of the update panel) the users are retrieved from SQL server and displayed in a repeater inside this update panel. Each of the users has a button next to them to 'Edit'. The seconds update panel contains all of the fields for a user. Textboxes, checkboxes and what not.
My plan is to click the search button as you normally would, and then when you click the 'Edit' button on a user, the second update panel fills with their details. This works except that when I do this the first update panel is updated again and because it hasn't searched for any users it goes blank.
So what I did was set both the update panels to conditional, and then call the first panels update at the end of the search code in the search button click event. So that worked, but now the repeater inside the first update panel is not firing the Item_Command event, so I can't get the details for a user. How can I resolve this so that the repeater button works inside the conditional update panel?
I have a web page devoloped in visual studio 2008.I have 4 dropdowns and a repeater in the page.based on the selection(search criteria) from the dropdowns the repeater value will change and one dropdown selection will bind values to the other dropdown also.Since the page is causing a lot of postback we decided to implement ajax here.I am yet to learn ajax.which ajax control replace dropdowns?
i have already server side code written on all dropdowns.Please give me a good solution which i can implement in less time and reuse my code.One more update: i have a master page used in the project.I am using update panel of ajax which does not work if i use master page.(That means all the dropdown controls and repeater i put it in update panel.But still page postback occurs.)In a normal page(without master page) it works?
I have a bit of a strange problem and wondering if anyone can help.I have an update panel that has a timer set as the AsyncPostBackTrigger. In the repeater I have a few buttons which have on click events.The on click of these buttons does not appear to fire until the timer has ticked. My code is as follows:
I have a user control, that has an update panel and update progress control in it.
I use this user control in more than 1 location on the same page.... problem is, when ucA posts back, I see the update progress control for both ucA and ucB. I assume this is because it is a user control and the update panel and progress are named the same?
Either way - how do I make it so that the update progress only displays for the proper user control?
I've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.
Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.
This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.
I have a repeater that has a delete button in it.When the delete button is clicked the panel updates and returns, then the row is deleted.So the deleted row stays in the repeater until i navigate away and then come back to the page. I commented out the update panel and all is good except i really want the update panel as the flicker is not pritt
Im implementing a simple form with ajax to warn the user if email has been used or not for registration, and it looks to be working fine with IE but mozilla does a full page postback and refreshes the whole page.
I already tried changing to updatemode to conditional, all the triggers are set as async, etc but mozilla keeps doing the same, Im sure it is a known problem I may not be the first one facing this problem so i guess there is a simple workaround for this.
I have a form, with an update panel and the EnablePartialRendering set to true on the page. Here's my problem, the page size with every AsyncPostBack gets larger, even if my code makes no changes to the markup. It also, never stops... it just keeps growing about 3-4K with every AsyncPostBack. If EnablePartialRendering is set to false, full postbacks do not cause the page size to grow like that. It's like it's sending resources and then never getting rid of them out of the page even though they're not being used because an updated copy has come down.
1.) Is it supposed to work like that?
2.) If it's not, what can I do to not have 4K added to the page size everytime an AsyncPostBack occurs (not again, full PostBacks do not have that same behavior).
3.) This behavior happens whether I compress the ViewState or not (I am using ViewState compression). However, the ViewState size is NOT growing... it's the size of the content in the page that is (I'm monitoring the ViewState size/the Page Size closely).
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 one update panel inside updatepanel i have one dropdownlist .When i change dropdownlist value so as per value button1 which is out of updatepanel not visible =true or false as per dropdownlist value.
I have a created a form using a user control. One of the dropdownlists in the form is populated after the user makes a specific selection from another dropdownlist...i.e. a dependent dropdown list. This is triggered using the SelectedIndexChanged event handler on the controllling dropdownlist.
The dependent dropdownlist gets populated correctly, but when I choose one of the options and go to submit the form, the dependent dropdown list is reset and doesn't maintain the selection that was made.
The controlling dropdown list ID is "level". The dependent dropdown list ID is "EnrollmentSize".
The "EnrollmentSize" DDL only losses the option that was selected. The DDL is sitll populated with all the correct values. It only losses the option that was selected and goes back to the first option...i.e. "Select..."
The viewstate on the page is enabled and all the other form values are maintained. It is only happening with the EnrollmentSize ddl.
I've set breakpoints and tried debugging and I do see that the EnrollmentSize.SelectedValue is an empty string, but I don't see why or where that is happening in the button click event
I thought it had something to do with EnableViewState,but that is set to true and has no bearing. Everytime I try to submit the form, the "EnrollmentSize" DDL is reset and doesn't maintain the option that is selected.
