Web Forms :: Update Panel With Repeater / UserControl
Feb 23, 2011
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?
I am working in asp.net 4.5 with VS2013. I have two usercontrols in my aspx page and in my first usercontrol i have gridview with button inside update panel and if i press the button it should pass the value to second userconrol and based on the value i will do some db operation to bind the controls in second usercontrol.
I am wondering is it possible to achieve using AJAX? I need to do this with partial postback without posting entire content of the page.
I have a user control which acts as a footer for my website and uses java script jqdock.js to show apple type bottom menu. I added an update panel to the usercontrol. What problem I am having now is, it works fine initally but once I click the mail button which is in the usercontrol , the whole user control dissapears, after postback i guess. below is the usercontrol and code view:
enter code here
public void Page_Load(object sender, EventArgs e) {
I have Dropdownlist and Datalist in Usercontrol. Images in Datalist will be loaded
according to Drodownlist Selected Value.I have placed the Usercontrol in Page with Update panel. So Now Usercontrol is placed With in Update Panel.the problem is Datalist is not Updated Properly. according to the Dropdownlist Selected Value.Can any one solve this issue.
i have a javascript color picker i can get it working fine in a aspx page, but i am unable to get it working in a usercontrol inside a update panel. I have tried using the following but i still cannot get it to workm the js file can be viewed at [URL]
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]
The subject is explanatory, but here are some details:
I want to update a repeater when SelectedIndex value changes for a dropdown list. The problem is Nothing happens.
My aspx page is present in a nested master page. and neither autopostback works nor update panel. i have set the AsyncPostBack trigger on SelectedIndexChange event.
Please let me know what am i doing wrong or what am i missing.
PS: I have never worked on ajax before so I might have overlooked something.
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 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
We have two update panels on our webpage. Now first update panel is having button cancel. While second update panel is having a file upload control.
Now if the user uploads a file that is going to upload in about 2 mins, and in between, say after 30 seconds the user clicks the cancel button, the upload taking place in update panel 2 should stop.
I think I am not a beginner in asp.net, but now maybe I dont see the solution because it must be so easy..I have a simple Repeater on an UserControl(ascx).After a Postback on a button click I would like loop trough allthe Items from the Repeater, but the RepeaterItem-Collection is Empty!!!!!But NOW it comes, when I move the whole code from the UserControlto the Codebehind of an Page, and move the Repeater also to the Page.It works!!!! The Items-Collection are not empty after the Postback!!!Here is the simple Codebehind from the UserControl:
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 my master page with one update panel working like a banner, so when the timer do tick every 5 sec
the image change. That works fine, but i have an update panel in my index page, this update panel works with some buttons that change the text inside the panel when click.
Now, the problem.
When i click one button to change the text and the banner change, the text returns to his default text. The update in master page is affecting the update on index page.
I am using asp.net 3.5 c#. I am trying to do this:
In one page, a user can insert some stuff (name, phone .. etc) to the database. And then the user should be able to see the rows he added as a list automatically in a datalist (or other control). As he inserts rows, it appears in the datalist.
I tried to use update panel and inside it datalist, with a button as a trigger but it did n't work with me!
I need to set the ParentItemID variable for the uc1:pdf listed inside the repeater. I thought I should be able to find uc by looking in the e.Item and then setting it somehow. I think this is the part where I'm missing something.
UPDATE: It looks like my controls are not connected by a namespace. I've wrapped by the parent control (Layer) and the PressFileDownlad control in a namespace "MyControls". Also updated their Inherits reference on the aspx to read "MyControls.xxxxx". I'm able to type "MyControls.Layer" inside the code on layer.aspx.cs but I'm not able to get "MyControls.PressFileDownload"
I have a panel bar..each time I press panel bar item I display ascx control with in update panel..but it lakes update panel loading time lot..how I can decrease that loading time?
I have an AJAX Modal Popup panel that contains a RadioButtonList, 2 labels and 2 DropDowns. I want to update the Labels and DropDowns when a radio button is selected. My attempt at this posts back which causes the ajax popup to disappear.
aspx called on image click: <asp:Panel ID="pnlModalContainer" runat="server"> <asp:RadioButtonList ID="rblTest" runat="server" RepeatDirection="Horizontal" OnSelectedIndexChanged="rblTest_SelectedIndexChanged"> [code]...
I'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.
I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.
When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.
I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.
