I am not able to get the htmlinputimage control id created dynamically based on no of rows reterived from db.
these controls are bn created in usercontrol (.ascx.vb) page
The actually requirement is ...there are set of images in a table, i need to get a particular image src, based on that i need to collect the image id(s) and use it for futher process...
and this is poosible using a FindControl... which i have bn trying , but all invain...
I have quite a simple requirement, but strangely can't seem to find anything relevant & I'm not able to currently get it to work. I have created a master page with a a page header and footer, and left two contentplaceholders in it, one to add to the <head> html tag and one in the <body>. The idea is that users can then easily change the content or title of a page in a table without having to open an IDE of any kind.
The result is my page template looks like this:
[Code]....
Basically, I want the user to be able to paste all of their HTML into a DB table, and I will pull it out and put it into these placeholders. Most methods I've seen involve using extra controls, but surely there is a way to just enter text (that will be html) between the <asp:Content></asp:Content> tags on the Page_Load event?
I am having difficulties how to construct my question, but if I have to put it simply the situation is that I have categories of products. I have an aspx with a repeater on the left that lists the categories. And I want the products to be listed on the right. Category number is variable so I made an ascx with a DataList in it. When I try to do foreach category, ascx = new ascx(); then the DataList within this ascx control is null.
ps: what I want to do is to preload all the products (thre is not much) and hide the divs and fadein fadeout them using jQuery when a category div is clicked.
rightnow it is using jQuery.load(); and I don't like how the images load, cuz they download from top to bottom. Progressive gifs alsdo not an option. site demo is here [URL]
Ive got some custom code that im using to load user controls dynamically depending on the option a user selects from a menu control on the page.
I wanted to create an admin page that can be used to provide a one stop shop to complete all actions within an app im building, (like a template/iframe scenario that loads all selections in a screen on the right)
My code works, however when the user has completed an action sucesfully within one ascx, then selects another from the menu on the left, it wont load the new control, it comes up blank like it hasnt refreshed properly meaning that they have to close down the page and reopen it. (which is very annoying)
My codes below, can someone take a look and see if they can see whats wrong.
apologies beforehand for what can possibly be a daft conceptual question. I have an ascx control that has a bunch of ASP labels and buttons in the ascx page and some other public methods and properties in the code behind. When I drop this ascx control in a page it all works fine. I now have a page with a placeholder and I am trying to dynamically create an instance of my ascx control and put it there. I then reference this control in code and while all public methods and properties are available (ie MyControl.TitleString = "Hello";MyControl.DoSomething();) none of the ASP controls are. Rather, they are all null. So MyControl.buttonSave is null, MyControl.LabelTitle is null, etc. Is this by design? Am I missing something? If not, what's the point of being able to create dynamically do this?
How do i refer a control id from a different ContentPlaceHolder by using inline code?
I have filterParameters which refer a control (txtSearch). Since it was place in different contentplaceholder (ContentPlaceHolder2) , its id could not be find by it name "txtSearch", is there any inline code syntax can help me?
I'm developing an ASP.NET application with C# and Ajax.I have a page that holds user controls loaded dynamically. I need to pass some data (integer values and some strings) to the user control that has been loaded dynamically.Now I use Session to pass these values, but I think I can use another way; something like VIEWSTATE or hidden input.What do you recommend me?The fact that I load the controls dynamically is important because controls are loaded on every postback, and I can't store any value on controls.
I have a asp.net webpage which is using an Master page and contentplaceholder.
My Req: I want to access the control name through javascript.I have tried to use 'document.forms[0].elements[i].name' but its giving an error since my page there is no form.Only master page and contentplaceholder.
I have a dropdown list on my homepage which users select a category. After selecting the category, user will fill a form which has related controls to that category in it.
As I have many categories, I just want to have single ascx page and adding controls to it dynamically according to the user choice.
For example: One chose Telephone category, he will face a form having drop down lists asking, what brand? what color? And one chose, book category, he will face drop down lists asking which type? howmany pages?
So 1 ascx must do my work at runtime done as I have alot of categories.
I am going to take these criterias from a database table which has CategoryID and Criteria colomns.
And if I can do that, will it be possible to add field validators to these dynamically created controls.
I'm developing an ASP.NET application and I'm trying to do the following:
I'm going to have only one ASPX page splitted into two columns. On the left column is going to be a TreeView, and on the right column is going to be something to edit treeview's nodes.
When the user can select a treeview's node to edit on the right column. Depending on the node's depth fields on right column will vary.
I wondering to use ASCX controls and load on right column dinamically using AJAX, for example. Is there a better choice? Can I do that?
I don't want to reload the entire page when the user wants to edit a treeview's node. Maybe I'm going to need an UpdatePanel on the right column to load dinamically ASCX controls, isn't it?
Now, basing on some condition I would like to show/hide a given div. So I am trying to reach one of those divs by Controls collection, like this:
public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { ContentPlaceHolder myContent = (ContentPlaceHolder)this.Master.FindControl("ContentPlaceHolder1"); myContent.FindControl("TestDiv1").Visible = false; //this is not working } } } }
But the above example is not working. None of the two div control exists in the myContent.Controls collection. If I place for example a TextBox on my content page, I can reach it through Controls.
So what should I do to be able to access the div control?
is anybody interesting in share and join to develop callback web controls. My purposes is lower unsynchronized page development cost. I have developed a base class and a set of common controls. Currently, they allowed to be loaded dynamically in a control or ASCX via callback event using sample server side code. Control library code will automatically register javascript and render it on client browser. These controls worked fine in both callback and postback. To load dynamically from an ASCX file.
'ascx1.ascx contain some callback-able controls Private Function LoadAscx_DuringCallback(Optional ByVal RenderMe As Boolean = False) As String Dim rt As String = "" div1.Controls.Clear() Dim c As Control = LoadControl("~/Test2/ASCX/ascx1.ascx") c.ID = "ascx1" div1.Controls.Add(c) If RenderMe Then rt = CallbackManager1.RenderControlHelper(c) Return rt End Function Or to load dynamically as a control 'c is a callback-able TextBox Private Function LoadControl_DuringCallback(Optional ByVal RenderMe As Boolean = False) As String Dim rt As String = "" div1.Controls.Clear() Dim c As New ACT360_CallbackControls.ZYH.TextBox AddHandler c.KeyUp, AddressOf TextBox_KeyUp AddHandler c.GetFocus, AddressOf TextBox_GetGocus div1.Controls.Add(c) If RenderMe Then rt = CallbackManager1.RenderControlHelper(c) Return rt End Function
I am adding controls dynamically to PlaceHolder which within ContentPlaceHolder
var t = (ContentPlaceHolder)Master.FindControl("ContentPlaceHolder1"); var t1 = (PlaceHolder)mpContentPlaceHolder.FindControl("PlaceHolderName"); var t2 = (DropDownList)t1.FindControl("ControlID");
It looks like I am missing something because t2 is always null
I have an issue with gridview and ascx's inside. Into the item template I'm dynamically loading ascx files depending on the row hiddenfield value. Ascx control is then "opened" in panel with modalpopup extender. The issue is ascx control with ceratin programming logic behind does not postback in this scenario.
I'm using a Master Page with two content areas to render a two-column format.In the left column (Content ID="Left") I have an UpdatePanel (ID="ChoosePanel") with a TreeView control whose ID is "StickTree".In the right column (Content ID="Right") I have another UpdatePanel (ID="ChartPanel") with UpdateMode="Conditional" and the following trigger:
There should be no problem having the trigger in a different UpdatePanel, but I'm getting the following exception when I run the page:A control with ID 'StickTree' could not be found for the trigger in UpdatePanel 'ChartPanel'.
I have .ascx web user control in my web site. Now I want to make dll for that .ascx file. let me know steps how can I make .dll file for that .ascx web user control.
I have a master page with a ascx control I use for a header. There is a label in HeaderControl1 I need to set from the content pages. I was able to make the changes in the master template as a tes by just calling the control and accessing the property.
I want to set the focus to a specific control in .ascx from main page. When i load the mainpage.aspx, the focus should be on a text box control which is contained in web user part called selectperson.ascx
I have a variable in an aspx file I need to use/recover it's value into an ascx web control that's in this aspx file. It's possible to do it? The aspx dynamically loads web controls depending the scenario, so this web control not allways is loaded.
I have written a web usercontrol (ascx). Inside, there is a Panel that I want to show/hide on click of a hyperlink inside the usercontrol.
Normally, this is easy just by doing something like this (the onclick attribute is added to the hyperlink on prerender):
var PanelToShow = document.getElementById('<%=PanelInvoiceHasBeenCreated.ClientID %>'); if (PanelToHide != null) { PanelToHide.style.display = 'none'; }
but because the ascx control is held within the gridview, the above will assess all the controls (of which there are many in the gridview) with the name 'PanelInvoiceHasBeenCreated'. The only time it will work is when there is 1 row in the gridview. Currently, with my existing code, if I click the hyperlink in any row, it shows/hides the panel in the bottom row of the gridview!
Therefore, my question is how do I get the actual, unique ID I need to show/hide on the correct control in the correct row?
