now i m trying to show the result in the label by taking the update panel but its not displaying
I have an update panel and data list. Data for this fields are loaded from database (to the textbox).
The save button should write data to database, unfortunetly it dosen't. Instead are loaded empty data. I think The reason is that the textboxes are inside updatepanel.
I tried to make an attempt to with Label. Data where to show from the textbox, instant i have an error:
Object reference not set to an instance of an object.

I have an update panel that contains a textbox..I would like a situation when on selectedindex_change of one of those textbox to have my update panel containing the textbox invisible and then when another button is click to have my update panel containing my textbox visibile again. How do I do that.
View 1 Repliesi have a Textbox inside an update panel, and each time the timer interval hits, anything being typed inside the textbox clears.
Is there anyway i could make the textbox retain the text inside while the update panel still updates?
I have a update panel that is being refreshed every second or so, and the user is inputing data into this gridview via a textbox. when the user presses enter or send i would like the text box to be cleared. I call it to be cleared on my button event but it doesnt. It post to my gridview perfectly but it will not delete the text. I am assuming becasuse the control is outside of the update panel or the timer is a problem, I was looking around for a answer and saw to complete this you have to use java script. Can someone show me how to implement this in my code,
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"

I just added update Panel for Ajax..
Inside the update Panel I added few controls, which I cant Access them regular
like TextBox1.Text.
What should I do?
Strange problem, not sure why it's happening. Basically I have inside an UpdatePanel a dropdownlist, a textbox, and a regex validator. page loads, ddl is bound and then based on the value in the ddl, a different regex is applied to the textbox. DDL could have search by "date" (with date regex), "last name" (with az regex), or "zip code" (with a zip regex). This way one search box can be used with 3 different regexes. Select zip code in the ddl, the OnSelectedIndexChanged is fired and the new regex is applied to the textbox. Simple.
The problem is, though, is that the page loads, I select Zip Code in the DDL, type in a zip code and then tab out NOT clicking the search button, and as soon as I do the regex validator fires with the red *. I wait about 2-3 seconds and it appears there's a postback that's fired somewhere because the textbox gets cleared out. Here's the update panel.
[Code]....
There is nothing in the code-behind that causes any postback except the dropdown list that applies the appropriate regex to the textbox.I see no reason why after 2-3 seconds the textbox gets emptied out. Is there a way to stop this?
I have the Textbox inside Update Panel
<td colspan="4" style="border: none;">
<asp:UpdatePanel ID="upnl_Period" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:TextBox ID="txtDate" runat="server" Width="90px" ValidationGroup="ReqForm" Text='<%#(((System.Data.DataRowView)Container.DataItem).DataView.Table.Columns.Contains("Date")? Eval("Date") : " ") %>'></asp:TextBox>
But iam getting the below error
CS1061: 'System.Web.UI.Control' does not contain a definition for 'DataItem' and no extension method 'DataItem' accepting a first argument of type 'System.Web.UI.Control' could be found (are you missing a using directive or an assembly reference?)
How i assign the value to Textbox which is inside Update Panel??? IF i remove the Update Panel every thing is working but i do with the update Panel . i dont want to page full postback.
I am building a Web Content form in which the user enters some data in asp:TextBoxes, and presses submit to store the data in the database.
I am using an Upadate Panel, in which I have put the afore mentioned asp:TextBoxes. Is there a way to set TextBox.Text = string.Empty after the submit?
Note that I have implemented code, which sets my TextBox.Text = string.Empty in my aspx.cs file, which of course does not work since I am using the update panel with an AsyncPostBackTrigger...
I added a user control on master page and inside UserControl i add a link. and did some stuff on click of link.
Again i add another Content Page that is using the user control not the master page. Inside the table i add some textbox and save values in database . and the table is in UpdatePanel. and added ad trigger
<Triggers><asp:AsyncPostBackTrigger ControlID="btnUpdate1" EventName="Click" /></Triggers>
When i remove the usercontrol entering on table textbox values works fine. and again i put the same user control the link button contol doesn't work for me.
I used timer to refresh page every 5 second.. but due to timer my multiline textbox doesn't scroll down bottom even though i used javascript to scroll to bottom..
This is my code

<head runat="server">
<title></title>
<%--<style type="text/javascript">

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.
How do we achieve this ?

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.
i have a panel out of update panel.i have to make it hidden while navigating through different tabs,i tried these codes
Panel1.Attributes["style"] = "display: 'none';";
Panel1.Attributes.Add("style", "DISPLAY:none;");
I have a formview in Edit Mode, within an update Panel all and these arewithin a Modal Pop Up extender.On clicking Formview Update button, I want an image to appear within the pop up.I have put the image within another panel1 and runat server.For some reason the image is not showing on clicking update button.
View 13 Replieshow to catch update panel's request start (before partial updation request is sent to server) and response receive (before update panel is updated) events.
View 1 RepliesI 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.
<cust:CustomControl runat="server" ID="CustomControl1">
<asp:UpdatePanel runat="server" ID="UpdatePanel1"> <ContentTemplate>
<asp:Button id="Button1" runat="server" OnClick="DoStuff" />
</ContentTemplate> </asp:UpdatePanel>
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.

PROBLEM: So how would i update this using an update panel and timer. Currently when i do it the chart just disappears on update. I believethis is due to the fact that i am calling a dataURL. How would i get this to work javascript?
I am building a system for a school project. I currently have several Update Panels on the page that have many different controls on them. I also have a single Label control that i use to display messages to the user. I would like to have this label within an update panel also but there are literally hundreds of triggers that would require it to be updated and i dont want to type an absurd number of triggers for this one control.Is there a way for me to have this one panel update regardless of what happens?
