I'm dynamically creating image buttons and want their click event to update an image in the update panel where only the panel updates- not the whole page.
I have created the image buttons click event and got it so that it updates the image in the update panel, but I can't seem to create the triggers- I keep getting the error 'Multiple Controls with the same ID' and I can't understand why.
Here's my code:

I want to try and use an updatepanel. So I have surrounded this code with an updatepanel.
Now I need to put "LinkButton57" as AsyncPostBackTrigger. It seems that I cant put that in the HTML code in the Trigger tags as the updatepanel only searches for parenting controls.
This LinkButton57 is located deeper in the control hiearchy as you can see here. So I am trying to put this programatically in the Page_Load event.
Now if I run the below code, I get this exception(Object reference not set to an instance of an object) and wonder if I could be thinking right here and just miss some details perheps? Will be happy for answer.

I have a problem with adding programatically FilteredTextBoxExtender (i put the code below).
The problem is that nothing is outputed when page is renedered although TextBox and FilteredTextBoxExtender are added to container (table cell controls property in my case).

I've tried looking for examples but can only find something setting properties for animation. Is it actually possible?
For some reason I can't get the button event to fire...
This is my Accordion:

These two should get fired - but they dont:

I read somewhere that I should add the button to the UpdatePanel

But when I do I get this error :
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
I have the following code in Page_Init (actually in a function called by Page_Init in response to a __doPostBack call)
System.Web.UI.WebControls.DropDownList ddlGroup = new System.Web.UI.WebControls.DropDownList();
rowString = rowNumber.ToString();

my page is using an UpdatePanel to do some ajax function after a button click. So here is what I got.
I have a textbox and a button.. The button clicks and the animation fires... But i dont want that, I want to validate the textbox and if everything is ok then fires Animation. Here is the code. My question is how can I fire this animation after all validations are ok?

I have an ASP.NET Label on my form, which is wrapped in an UpdatePanel. The UpdatePanel has two AsyncPostbackTriggers which reference two DropDownList controls. Based on the combination of selected items in both DropDownLists, I'm updating the Label. I also have a FilteredTextBoxExtender referencing an ASP.NET TextBox that's, by default, only allowing numbers. Now, along with updating the Label based on the combination of selected items from both DropDownLists, I'm also changing the FilteredTextBoxExtender's FilterType to Custom | Numbers and ValidChar to a hyphen, to allow both numbers and a hyphen (for phone numbers). Remember that I have both DropDownLists as AsyncPostbackTriggers for the UpdatePanel. This works perfectly fine doing a regular postback, but if I add those two DropDownLists as AsyncPostbackTriggers, the FilteredTextBoxExtender is not working properly based on the FilterType and ValidChar properties. It only allows just Numbers, which is the default. Is there anyway around this without having to do a regular full postback?
View 3 RepliesI am converting an old payment page from classic ASP to ASP.NET. The page includes three radio button options (credit card, purchase order, bill me). The old page uses javascript to enable/disable the appropriate input fields depending on which payment option is selected. For example, if the payment selection is changed from "credit card" to "purchase order", the credit card fields are disabled, and the PO number field is enabled.
I want to mimick this behavior using ASP.NET + server-side AJAX, so I created RadioButtonList for the payment options, and put all the data input controls (credit card number, purchase order number, etc.) within an UpdatePanel. The UpdatePanel has an AsyncPostBackTrigger with ControlID set to the RadioButtonList, and an EventName specified which tries to enable/disable the appropriate input fields depending on which payment option is selected. This doesn't seem to work because changing the radio button selection doesn't seem to fire this trigger.
Is it possble to utilize AsyncPostBackTrigger with a RadioButtonList control? If not can you suggest a way to handle this scenario for dynamically enabling/disabling form inputs?
I have a user control 'UserControl1'.
Which is in update panel of ajax.
Now i want to use trigger in update panel.
Then what should i write in eventname of trigger
<Triggers>
<asp:AsyncPostBackTrigger controlid=" UserControl1 " eventname="????" />
</Triggers>
I have a very simple application that works almost all the time. I am using an UpdatePanel. My script manager is configured to enable partial rendering. My UpdatePanel is configured for conditional update mode. My asynchronous trigger is a timer that runs every 3 seconds. I track unhandled exceptions in the database. I am not getting any unhandled exceptions. Nor am I getting managed exceptions. Now, I had two users side by side running the application today. I had one record in the data queue. The first user did not get updates; her grid did not update. The second user did get updates. The only difference was that the first user was logged in for a long period of time. The second user logged in just before the test. I reviewed the IIS log file and both users were polling the page every 3 seconds for the same data. So why didn't the first user's grid update? The code follows.
<asp:ScriptManager ID="ScriptManager1" runat="server" AsyncPostBackTimeout="30" EnablePartialRendering="true"></asp:ScriptManager>
[Code]....
In my code behind I have the following timer logic. [Code]....
AsyncPostBackTrigger doesn't work on server?
View 4 RepliesIn updatepanel we can use triggers with two methods AsyncPostBackTrigger and PostBackTrigger so I want to know what is different between these two as well how can we decide we need to go for which one.
View 3 RepliesI have a TabContainer with a few TabPanels. Inside the first TabPanel there is a GridView that have a LinkButton called "Subject".
Now when this "Subject" is clicked I want to change the TabIndex to another TabPanel so I have created a clickevent for this below.
I want to change TabIndex using an UpdatePanel to not have to do a fullpage postback.
So I need to put the "Subject" in the AsyncPostBackTrigger but it says it cant find the control so I wonder how I would do this for this LinkButton "Subject" ?

have update panel that content check box, textbox, 3 DropDownList with CascadingDropDown extender. When I checked the checked box it should do a AsyncPostBackTrigger and it is working ok but the problem that if I select any thing from DropDownLists then check the box it would clear the DropDownLists after doing AsyncPostBackTrigger for the the check box.
any advice how to separate these controls inside update panel for doing AsyncPostBackTrigger??
I want to add StyleSheets programmatically in the head section but one of the examples I saw seemed to need to many lines of code to add just one style sheet even though I may need a lot: Example Code:
HtmlLink css = new HtmlLink();
css.Href = "css/fancyforms.css";
css.Attributes["rel"] = "stylesheet";
css.Attributes["type"] = "text/css";
css.Attributes["media"] = "all";
Page.Header.Controls.Add(css);
I also use Page.Header.RenderControl() method but it didn't work either. Object null something error was thrown. I also used Page.Header.InnerHtml and InnerText += "<link .... "/> things but they threw the Literal error which is I think common error. I used this code :
List<Literal> cssFiles = new List<Literal>();
cssFiles.Add(new Literal() { Text = @"<link href=""" + ResolveUrl("~/Resources/Styles/MainMaster/MainDesign.css") + @""" type=""text/css"" rel=""stylesheet"" />" });
cssFiles.Add(new Literal() { Text = @"<link href=""" + ResolveUrl("~/Resources/Styles/MainMaster/MainLayout.css") + @""" type=""text/css"" rel=""stylesheet"" />" });
AddStyleRange(cssFiles);
private void AddStyleRange(List<Literal> cssFiles)
{
foreach (Literal item in cssFiles)
{
this.Header.Controls.Add(item);
}
}
It worked at first but when I change the pages it stopped working. I am using Master Page and I am writing these codes on Master.cs file and also some people recommended to use this.Header instead of Page.Header but when I built it throws an error which says I cannot declare that like this. It shouldn't be that hard to add many styles.
What I would like to achieve:
I would like a user to be able in insert a row into the listview. BUT not into a database.
What I am stuck on:
Currently I am stuck on the OnItemCommand, i dont seem to be entering the method. Code below.

I have a user control that needs to load a child control when a button is clicked. The trouble is that it has to request the control from another class.
So in the button click event, I call the function to get me my control, and add it to the page, like this:
UserControl ctrl = ExampleDataProvider.GetControl(some params...);
myDetailPane.Controls.Add(ctrl);
The GetControl method looks like:
public static UserControl GetControl(some params...)
{
ExampleDetailPane ctrl = new ExampleDetailPane();
ctrl.Value = "12";
ctrl.Comment = string.Empty;
return ctrl;
}
This isn't working due to the page's lifecycle - the Page_Load of the child control gets fired and its controls are null.
I am developing a custom Web Interface Browser for Subversion Repositories with C#/ASP.NET and SVNKit (Converted to .NET assemblies using IKVM.NET). Is there any clean way to locally add a new subversion user (that is added by the administrator) using C# code?

View 1 RepliesCan anybody tell me how I can add ItemTemplate to a Template column in a GridView. What I am doing right now is that I am adding Columns to GridView from code. And now I need to add a Template column with a ItemTemplate.

I have to add row in gridview dynamically when a button is clicked on my page
Each Row which have to be added contains a dropdownlist(ddlQues) in which questions are binded
On selecting question from ddlQuestion I have to bind another dropdownlist(ddlAnswers)with respective
answers in that row of gridview
So autopostback property of ddlQuestion is set to be true
Everytime when button is clicked a new row is inserted in gridview and same process repeats............
I had tried following javascript:
<script type="text/javascript">
function AddNewRecord()
{
var grd = document.getElementById('<%= gvResponse.ClientID %>');
alert(grd);
var tbod=grd.rows[0].parentNode;
var newRow=grd.rows[grd.rows.length - 1].cloneNode(true);
tbod.appendChild(newRow);
return false;
}
</script>
and calling this function on button
<asp:Button ID="btnResponse" runat="server" Text=" New Response" CssClass="button3" OnClientClick="return AddNewRecord();" />
Also I tried to solve it by C#
By both ways(either by javascript or by C#)New Row is added in gridview
But when I select question from ddlquestion then page is loaded and and the inserted row in gridview disappears
I am using asp.net 2.0 with C#
