AJAX :: Gridview Disappear After Pression Button Inside UpdatePanel?
Jan 27, 2010
I am using UpdatePanel, and I include a gridview inside the updatepanel, I want the grid to be refreshed when button1 or button2 of gridview being pressed. But now when I click the button, the gridview disappeared and look likes the whole aspx is refreshed. I just want to refresh the gridview inside updatepanel. But now the gridview is disappeared. The following is
I've a ASP.Net page (Default.aspx) which will load UserControl (ucontrol.ascx) dynamically into an UpdatePanel. By using UpdatePanel, we believe we're able to prevent the entire page to be posted-back.
My problem is, within the UserControl, we have some form controls, such as inputs and buttons; after the UserControl is loaded, clicking on any button inside the UserControl will cause the UpdatePanel to be blanked. During the investigation, I found that, breakpoints within the Button1_Click() in the code-behind for the UserControl is never reached. Please reference to the code below, this references to [REFERENCE]1.
I have an updatepanel and in my updatepanel I have an button. OnClientClick property that; OnClientClick="return confirm('Can you delete this data?');return false;"
when I keystroke on enter key, button clientclick is work and there occur warning on my page .
I have an update panel and inside the update panel I have a button. When I click that button I want to show textbox which is hidden (i.e. style="display:none"). I want to do it from client side. I wrote a javascript to show the textbox. But the textbox disappears after it is shown.
my button code looks like this: <asp:ImageButton id="b1" OnClientClick="showTextBox();">.
showTextBox() code is called and it displays the textbox, but the click event goes to the server and comes back and when it comes back it doesnt know about the newly added textbox i guess. Is there an easy way to show the textbox from the client side without going to the server inside UpdatePanel.
I've a dropdown and a listview inside an updatepanel (Master/Child relationship) so based on value selected in dropdown the listview gets populated. The Listview allow user to perform Edit/Insert/delete of records. I have to implement a scenario when a user is editing/inserting a record and if he tries to navigate away/change the value in dropdown he should be prompted to save the data and if he choose yes in JS Confirm Dialogue then the currently edited/inserting record should be saved (for which i'm trying to mimic the click of the update/insert button using js). I've attached change eventhandler of dropdown using JQuery which is getting called properly bind. [Code]....
This code gets bind using Sys.Application.add_load(saveChanges); I also tried the following Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(saveChanges);Sys.WebForms.PageRequestManager.getInstance().add_endRequest(saveChanges). The eventhandler gets called correctly but the click() doesn't work! Also the reason I'm calling click() method of button is to perform the validations via RequireValidator/RangeValidators.
I have an update panel which is inside a Modal Popup Extender. When I click the Refresh Report button it always calls a postback. I need to stop it from posting back.
I have 2 "Updatepanel" controls. Each contains a textbox linked to a "TextBoxWatermarkExtender", and a button. When I click on one of the buttons without to enter any text, all the watermark text disappear on BOTH updatepanel when they should remain visible.
[code]...
How can I avoid the waternmark text to disappear when I click on the button?
In Visual Studio 2008 ,in my application page 'TEST.aspx' have an 'Ajax TabContainer' inside update panel , and Tab Panel "Product Group Identification" containes textboxes ,DropDownlist and button like 'Save' and 'Cancel' , on clcik of 'save' or 'cancel' buttons only dropdownList Disappears for a second and reappears this is due to Update panel.
I've got a rather difficult one here. I have a JavaScript jquery toggle button inside an update panel. Right now i'm using <form body="onload"> to recall this javascript to re-apply the button state after each partial postback. It works, but it requires two clicks sometimes.
The problem is... after a few clicks, it is significantly slowing down the PC, and I can see the clicks trailing half a second to nearly a second. If I have a group of buttons, all those click events are just catching up to my clicks. It is rather amusing but I suppose it has to do with the fact that the postback is calling the <body onload=" event> each time after the button is clicked.
I'm currently building a simple chat application and I have everything working real smooth except for one thing, and this problem is only in IE as far as I know (in firefox there is no problem).
In my chat application I have the textbox where the user writes the messages to the chat and the button that sends this message togheter in an updatepanel (so that there is no visible postback when pressing the button). I also have in the form tag "defaultbutton=" set to the button. The problem is that when the user uses Internet explorer and presses Enter instead of pressing the button with the mouse that after the 2 first times he/she does this causes the textbox to stop focus on it, which it shouldnt do as in the end of the button the code says it should focus, which works the 2 first times for some reason.heres the code where the problem exists:
aspx:
form id="form1" runat="server" defaultbutton="Button1"> <asp:ScriptManager ID="scriptManager" runat="server">
I have a button that is inside of an updatepanel, I want it so that whenever the user clicks on the button it would update items in the updatepanel and after that it would activate the animationextender but I can't do that as of now because on the button I have OnClientClick="return false;".
i am using vs2008. 1/ i am placed a datagrid control, a textbox and a server side button are inside the CollapsiblePanelExtender.
2/ The collapsible panel Extender placed inside the updatepanel.
3/ outside of updatepanel i have another button("next page") to redirect to next page.
When the page is loading, i am displaying all the records in datagrid. For an example 100 rocords. if i entered some values in textbox and click the button it fetches searching result based on inputs and displaying it in datagrid (for example searched result 20).
Now, I click the button "next page" it redirect to next page. if the user click the browser back button, i need to keep the datagrid to show only searched result. but Instead of that, it displaying all the records(100 records). how to resolve this?
Question for Print functionality in ASP.Net GridView control artical. I tried you code in my project, when click print current page, nothing happens.
So I download your code into my test web project "WebSite1", greate, it works.
Then in your CS.aspx page,
I added (which is the case of my project of using AJAX).
<asp:ScriptManager ID="ScriptManager1" runat="server">Â Â Â Â Â Â Â </asp:ScriptManager> <asp:UpdatePanel ID="UpdatePanel1" runat="server">Â Â Â Â Â Â Â <ContentTemplate> <div>Â Â Â Â Â Â Â <asp:GridView ID="GridView1" runat="server" .......................... gridview stuff gose here ......................... </div> etc etc to close all the tags.
Now run, click print button nothing happens, no any error.
Can you see why put updatePanle for AJAX causing problem ?
I also have to pur EnableEventValidation="false" at top of the page to avoid
I have a GridView and DetailsView in a Master/Detail relationship inside an Update Panel.The GridView displays a set of records, and when a Select button in the GridView is clicked, the detailsview displays the record for edit.Initially the focus is on the GridView, and when the Select button is clicked, I want the focus to be on the first TextBox inside the DetailsView. This happens only when I remove the UpdatePanel from the form. If the Gridview/Detailsview pair is inside an updatepanel, the focus never goes to the DetailsView.How can I make the focus on the DetailsView inside an UpdatePanel
I've got a fileupload control inside of a gridview so that each row (item from the database) can have an attachment associated with it. I've got a button next to the fileupload control (besides the default browse... button to select the file) to actually take the file and upload it to a file server. This works great if I use this button "Upload". However, underneath my gridview I have another imagebutton that is outside of the gridview, its just sitting on the form / page. The idea of this "Update" button is when end users make changes to the grid I can simply loop through the grid and update the values they have entered to the database. This also works great.
Now here is my issue assume a user has 3 rows in the grid view. On 2 of these rows he decides to add an attachment but he never clicks the "Upload" button he only uses the standard browse button to select the file. Now instead of clicking the "Upload" button that is on the grid view he ends up clicking the "Update" button outside of the grid thinking that it will save his attachments. So I decided to write code to grab the fileupload control from the grid using .FindControls("NameOfFileUploadControl") in my Update button loop where I loop through all the rows. Then I check if myFileUploadControl.HasFile property to see if there exists a file and if there does upload the file then continue with the code.
The issue is when I click this "Update" button .HasFile always returns false even though I can see the text string of the path in the fileuploadcontrol textbox (the standard one next to the browse button). Is it because this goes back to the page load event and checks if it is a post back? What causes this and how can I fix it? Im adding some code because im still confused with this
Protected Sub SaveGrid() For Each Row As GridViewRow In Me.gvLineItems.Rows Dim f As FileUpload = CType(Row.FindControl("fuAttachment"), FileUpload) 'todo: this part is not working If f.FileName.Length > 0 Then 'returns 0 always 'this returns 0. end if if f.HasFile() then 'this also returns false end if Next End Sub
This method gets called on a click of a button. The fileupload control is in an of a gridview that is wrapped inside of an UpdatePanel:
i have two nested gridview inside an update panel. there is a button called btnPhoneEdit inside the child grid view. when the button gets clicked, it do cause partial post back as expected but it fails to invoke btnPhoneEdit_Click.
here is how my grid view looks like and how i add my custom data source to both parent and child grid view. [Code]....
Altough questions somehow similar to this have been asked for a number of times, but the question is still unsolved. Here is the question: I have a gridview which is contained in a tab container ajax control which itself is inside an updatepanel. Gridview works excellent and its corresponding methods are fired accurately, but when I enable paging, (e.g.) after I click on page 2, the gridview hides itself. here is my PageIndexChanging method:
I have a ImageButton inside a gridview. The gridview is inside update panel. i want to redirect to another page with the Clicking of the ImageButton. But it is not working inside update panel. what should i do?

Now my datalist is under update panel hence on changing dropdownlist my textbox for city won't cascade. How can I update the context key on dropdownlist selection change ?
I hope this is a really easy question but I'm struggling with it. I have a GridView that has an UpdatePanel within a TemplateField.
The idea is that the user can make simple alterations without a full page load being required.
I have simulated my page functionality in the following example, which simulates a database hit, gridview databinding and updatepanel functionality.
When you press any of the + or - buttons in the GridView, the form controls in the bottom UpdatePanel also post their contents back. I have seen this by using Firebug. On my real page however this is causing excessive bandwidth and is nearly the same as a full postback.
how I can force ONLY the appropriate UpdatePanel's contents to postback for processing, rather than all the UpdatePanels?? I've tried experimenting with Triggers but just can't get it working properly.
