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'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...

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();
Can i Validate textbox inside gridview using ajax in asp.net
View 3 RepliesI looks like if you use the filteredtextboxextender control with number as the type some Mac browers don't let you paste text into the text box with the cmd+V. I have verified this with the filteredtextboxextender demo page.

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?

I need to filter user input into a textbox - as the user inputs the text (as opposed to examining the textbox on the textchanged event) The FilteredTextboxExtender does the trick, but there is a catch. I want to add formatting (currency) AFTER all of the input is collected in the textbox. The "FilteredTextboxExtender " prevents this from happening. This extender does have a property "Filtermode" which can be set to either "ValidChars" or "InvalidChars" at design time, but I do not know if it can be set at runtime.
Any solutions would be most appreciated. I am also open to other solutions to the problem - which is : do not allow chars other than numeric into the textbox, until the textbox has lost focus, at which time, currency formatting is to be applied.
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.

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
