I am using asp.net panel control in which I am adding two controls(a literal that contains some text and a checkbox) in code behind.
The code is something like this....
CheckBox checkBox=new CheckBox();
checkBox.ID = "chk_id";
checkBox.Text = "chk_text";
pnl_cityNames.Controls.Add(checkBox); //add check box
pnl_cityNames.Controls.Add(new LiteralControl("Some Text<br>")); //add some text
and to retrieve I am using this code.....
foreach (Control var in pnl_cityNames.Controls)
{
if (var is CheckBox)
{
int abc = 0;
}
}
When I run this code in the debug mood, It shows two added controls
1.)Text="Islamabad" checked=false
2.)System.Web.UI.LiteralControl
This is what the problem I am facing, it should add checkbox in the same manner as LiteralControl. So I am unable to get any condition to be true when I check the var for CheckBox in the foreach loop.
i have to access Textbox and check box values at same time those check box and text box created at run time .i know how i can retrive single controll but problem is that i want both control values at same time to add them in database
Consider the following code, adding 2 textboxes with the same ID (oops):
protected void Page_Load(object sender, EventArgs e) { string TextBoxName = "TextBox1"; Panel p = new Panel(); TextBox t = new TextBox(); t.ID = TextBoxName; p.Controls.Add(t); if (p.FindControl(TextBoxName) == null) // <-------******* { TextBox t2 = new TextBox(); t2.ID = TextBoxName; p.Controls.Add(t2); } Page.Form.Controls.Add(p); }
The code is designed to stop adding the same ID twice. However, the Panel.FindControl() method is not finding a control that was added in the previous line of code.
Am I using this in the wrong way?
I mean - sure - I could manually iterate through the controls in the next level, like:
string TextBoxName = "TextBox1"; Panel p = new Panel(); TextBox t = new TextBox(); t.ID = TextBoxName; p.Controls.Add(t); TextBox t2 = new TextBox(); t2.ID = TextBoxName; bool duplicateFound = false; foreach( Control c in p.Controls ) { if(c.ID == TextBoxName) { duplicateFound = true; break; } } if( duplicateFound ) { t2.ID = TextBoxName + "__0"; p.Controls.Add(t2); }
But I don't understand why this isn't working, whereas Placeholder controls and UserControls work fine.
The reason I am using Panels is for CSS styling. body > div > input - but still - it isn't working.
I'm adding a serires of asp:literal and asp:textbox controls to a panel in code as below (the eventual aim being to add only some of the controls depending on the user):
[code]....
How can I control how the panel is rendered, preferably without having to create a custom control?
I have a situation where i have unchecked all checkbox from a panel which havs some nested panels. I am able to clear checkboxes from main panel but nested panel's checkbox remain unchanged. My code is
XElement Categories = new XElement("Promotions", from b in db.GetPromotions() select new XElement("Promotion", new XElement ("Category",b.CategoryName), new XElement("Client",b.ClientName), new XElement("ID",b.ID), new XElement("Title",b.Title))); XDocument mydoc = new XDocument(); mydoc.Add(Categories); try { // Load the style sheet. XslTransform xslt = new XslTransform(); xslt.Load(@"C:WebDesktopModulesPromotionsTransList.xslt"); // Execute the transform and output the results to a writer. StringWriter sw = new StringWriter(); //XsltSettings mysettings = new XsltSettings(); XmlWriterSettings mysettings = new XmlWriterSettings(); xslt.Transform(mydoc.CreateReader(),null, sw); String mstring = sw.ToString(); It generates the following string: <ul id="red" class="treeview-red" xmlns:asp="http://schemas.microsoft.com/ASPNET/20"> <li><span>Arts & Entertainment</span><ul> <li><span>Client 1</span><ul> <li><span><asp:LinkButton ID="LinkButton2" runat="server" OnClick="LinkClicked" Text="Get your Free 2" /></span></li> <li><span><asp:LinkButton ID="LinkButton4" runat="server" OnClick="LinkClicked" Text="Get your Free 4" /></span></li> <li><span><asp:LinkButton ID="LinkButton5" runat="server" OnClick="LinkClicked" Text="Get your Free 5" /></span></li> </ul> </li> </ul> </li> <li><span>Community & Neighborhood</span><ul> <li><span>Client 2</span><ul> <li><span><asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkClicked" Text="Get your Free 1" /></span></li> </ul> </li> </ul> </li> <li><span>Education</span><ul> <li><span>Client 3</span><ul> <li><span><asp:LinkButton ID="LinkButton3" runat="server" OnClick="LinkClicked" Text="Get Your Free 3" /></span></li> </ul> </li> </ul> </li> <li><span>Home & Garden</span><ul> <li><span>Client 4</span><ul> <li><span><asp:LinkButton ID="LinkButton6" runat="server" OnClick="LinkClicked" Text="Get your Free 6" /></span></li> </ul> </li> </ul> </li> </ul>
Now I take the string and add it to a panel which is part of a view in a multiview control: Panel1.Controls.Add(new LiteralControl(mstring)); I have tried to play with Page.ParseControl, but I cannot get it to work right in the panel, the linkbuttons do not show, even though the text is there in the source. Now I tried this: Control myctrl = Page.ParseControl(mstring); Panel1.Controls.Add(myctrl); and I get this as the one of the controls:
a id="dnn_ctr954_ViewPromotions_LinkButton2" href="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("dnn$ctr954$ViewPromotions$LinkButton2", "", true, "", "", false, true))">Get your Free 2</a>
It doesn't work the way expected, dotnetnuke is doing some nutty stuff here using the parse control. it seems to drop my LinkClicked event.
Im working on app that queries another website, and pulls back an xml, I then populate a result panel with ImageButton(s), and time in a click event, when the image is click I want to popup a div box using the jquery ui, that will show more information, about the picture clicked on. however whenever id this this seems to wipe out my results panel(Panel Control) and the div box never appears and as far as I can tell the imagebutton click event never fires. I've tried doing this two ways one with an update panel and again without, I would appreciate any help on this.Im wondering if I'm doing to much long on my search button click, Im wonder if I should just let the post pack handle populating the result panel and ditch the update panel.(and yes my div tag is set to runat server)I'm also up for suggestions maybe there is a better way to do this, I thought creating hidden div tags for each item, and then running javascript for when the image is clicked and showing it that way, However that seems stupid, in my opinion it seems to make more sense to make my div control once and then update the labels inside it on each image click and then show or hide it.
I'm working on a simple demo project so that I can learn some things about ASP.NET's AJAX capabilities. My problem is that I can't seem to get an UpdatePanel to work properly with a CheckBox inside of it. Here is the markup I'm using in my .aspx file:
I have a check box, RequiredFieldValidator and textbox that have editmask extender I want to change the control properties programmatically when I check the check box but the problem that nothing happened when I check it.
I made the control post back and I added triggers.
when put break point and go with code step by step will go through the code but nothing change.
I have a simple Textbox for entering password and the checkbox named Show passowrd beside it. Textbox mode is Password by default. These controls are in the table and I am using Update panel on top of the table. My application framework is 2.0 and I am Using ASP.NET 2.0 AJAX Extensions.
Now When i write some text in the textbox and check the Showpassword chekbox then the checkbox event is not getting fired. when Second time i click it then the event is fired and text in the textbox is removed and the textbox mode is set to the SingleLine. This functionality I am achieving by writing a code in the CS File.
When I remove the Update panel then the event is fired correctly everytime, but when usign Update panel and some text in the textbox then i have to check the checkbox twice for the desired functionality.
This code works fine if i use this inside ssercontrol > panel and i have a checkboxes in table when no checkbox is checked its works fine .... but if i disabled and checked any of the textbox then this doesn't work .... in usercontrol why ? i didnt understand ..
<script type="text/javascript" language="javascript"> function checkboxChecked(){ var allInputs = document.getElementsByTagName("input"); for(var i=0; i<allInputs.length; i++) { var chk = allInputs[i]; if(chk.type == "checkbox" && !chk.disabled && chk.checked) {
return true; } } alert("OOps! You haven't selected all available checkboxes"); return false; } </script>
I have the following list of projects WebUI (WebSite) , DataAccess (ClassLibrary) , LogicLayer(ClassLibrary). Those of the project are purposively crated separately.But my scenario is, need to create only one solution file, then add all of the above projects under this solution file. So that i can be easiy interacted and changes can be made by opening solution file only instead of opening each project individually.
Simply all of the layer projects are under one roof means one solution. I tried it by adding solution first, then i added already existed project into this. But once after added already existing project the solution icon vanished by showing the icon of recently added project. By this way I could not add another project into this section too.Hope this is the way the basic real-time projects are created; to achieve the centralized control over architecture based projects.
I want to select all checkBox in Gridview when click to header checkBox.I have created design such that CheckBox is not available to header of Gridview.It is in other table. Below is design of gridview.
- How can I uncheck a checkbox using client side code when the other checkbox is checked? - Is there a way to check server side on form submission that at least one check box is checked?
I am displaying my table data using listview control. It is working fine.
Now I would like to add a checkbox in front of every item so then when user checks the checkbox and click on delete button inside or outside the listview control then i want all the records to be deleted.
I am absoluetly confused. My web app has a checkbox list that my code is looking to see if the user checked it. Like I said, very simple stuff... Here's the code:
If (chkLaunch.Items(1).Selected) Then Launch = 1 End If
The odd thing is that when it gets to this bit of code it just moves right past it like it wasn't checked. The same thing happens when I use a single checkbox (rather than a checkbox list). I've tried a bunch of different ways to make the code work but I'm left to the conclusion that I'm just not telling it to do this correctly. Either that or my project is messed up somehow.I say that my project is messed up because when I add an object to the page in Design mode, it doesn't write the source code. So when I save and close, all the modifications are mysteriously gone. This happens on multiple PC's...So, is the checkbox problem just me not doing something correctly or is my web project messed up?
I have a page with several panels. panel1 has a drop down list to select client. panel2 has two drop down lists to select facility1 and facility2. I want panel 2 to be disabled (both facility1 and facility2 drop downs disabled) until a selection has been made in panel1 drop down list. when a client is selected from dropdownlist1, I want to enable both dropdown list2 and 3 in panel2.
I have a panel and a background image. to stretch this image in the panel if the height is adjusting. I have tried to google this but have trouble find a solution for this.The image has the size: (647 X 158).
The only thing that will change is the height of the panel. Now it does repeat by default. no - repeat will probably only make the image its orignal size wich is not stretching it out over the whole panel.Otherwise I am thinking of change the size of the image itself in C#. [Code]....
Using VB, VS2010, I have a large image in a panel and want to be able to pop-up panels while hovering over it. This one large image is a picture of a lot of components that I woulld like to treat individually when I hover them. I have done this before by placing a transparent button in another panel that is absoultely positioned over the larger one. I have the button transparent with a border that shows up using hover in css. Everything works fine expcept that the panel does not show itself in the right place when viewiing in the browser window. It shows fine in design view, but shifts over while browsing in the browser. I have tried making all panels absolutely positioned. Still a problem. Is there a better way to put a panel over a panel?
