C# - Accessing Checkbox Inside Html Table Loop From Code Behind?
Feb 8, 2011
I have a question about asp.net
I have this table with checkbox for each row:
[URL]
table code inside the ASPX page:
[URL]
So I'm trying to implement the delete selected button.. How exactly do i point to the specific checkbox for a particular row from codebehind when all 3 have the same name chkSelected? I know how to do it with a gridview, but not quite sure how if we do it with a for loop..
Can I do something like this inside btnDelete_Click?
I have a report page, that displays many rows, each row having its own checkbox with its value being an ID field from the database.This is for a bulk operation, that will be preformed on all the row's where the checkbox was checked.So if the user checks multiple boxes, hits a button, I need to send all the checkbox values to a controller's action that will take those Id's and process them.
I wanted to know whether this is possible or not. I have a page with a div. I populate div at run time with a HTML table I wanted to access that table to get the data back.
I am trying with ParseControl() method... Not success Yet.
I've a web project where i've an Tab Container (ajaxtoolkit), and when i run the project it works properly. But when i debug it, it gives me erros in all the controls inside the Tab Container that i'm accessing through .cs code behind (buttons, checkbox, etc).
Visual Studio gives me "The name 'controlname' does not exist in the current context". This happen to all controls inside the Tab Container that i'm accessing in code behind, but the Web project is running with no problems! As it's the first time that i use an Tab Container, i don't know if this is normal or maybe of Visual Studio 2010 RC (or not).
Now that I put this html inside a Tab containe (subpanel) the Page.Request.Form["Name"].ToString() fail, actually while I was debugging I could not find this element inside Page.Request.Form.
maybe there is another way of accessing the Html element from my c# code?
I created a aesthetic control that creates two lists in seperate div tags organized with a table for each. The control always the user to click on the img tag associated with each item to move it between the two lists. I am doing all the movement between the lists via javascript and want to have a good method for obtaining the values and storing them in two lists upon Postback. I thought of doing something like storing the indexes/classes in hidden values and them reading them to find the items but that seems messy. Also, thought there might be a clever way of traversing the DOM via FindControl() but not sure. Any input would be great.
One other thing is that this is not a composite control. All the tags are being rendered in the RenderContents() method. So I don't know if there is a way to even tack on a runat="server" attribute to an elem like I normally would if I wanted code behind access to an html element.
Here is the HTML that is generated. I don't think there is need to post the server side code since it does nothing more than generate the html at this point.
i have got a HTML table which contain a check box in and other checkboxes in i want that all 's checkboxes should be checked /unchecked on basis of 's Check box..
<script language="javascript" type="text/javascript"> function SelectAll(id) { var frm = document.getElementById('tblemail'); for (i=0;i<frm.elements.length;i++) { if (frm.elements[i].type == "checkbox") { [code]...
I have created a web user control I want to change the iframe' src value when the user click on the link but the problem is that I dont have access to iframe inside the page from web user control I think there is a way because my control is in the page they have some relation perhaps I like to find something like this :
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>
Field "image1_path" has value "myPic.jpg". If possible, I need to parse this field within the html so that I can add "_3" to the name of the file, and then add the extension. The new string would be "myPic_3.jpg".
I don't want to touch the codebehind or the database.
I am trying to build a double elimination tournament bracket and the data controls are too restrictive. I am playing around with an html table but cannot figure out how to bind the data inside it easily. I would love to databind inside specific td's but it doesn't work at all.Here is what I have:
I receive a potentially dangerous request.form value was detected from the client when trying to submit text box with html code inside it I turn ValidationRequest="false" in the page and in the web config file also I put this settings <httpRuntime requestValidationMode="2.0"> but I still get the error, I'm using ASP.Net 4 with Visual Studio 2010.
I have a table with lots of fields. To display every record that has lots of columns on a web browser will inconveniently force the users to drag the scrollbar to the right.
Is it possible to divide each record to two or three inner rows in gridview?
e.g. My table has these fields: - UPC - Description - AdType_Week1 - AdType_Week2 - AdType_Week3 - AdType_Week4 - AdType_Week5 - Price_Week1 - Price_Week2 - Price_Week3 - Price_Week4 - Price_Week5 - OrderStatus_Week1 - OrderStatus_Week2 - OrderStatus_Week3 - OrderStatus_Week4 - OrderStatus_Week5
Instead of showing everything in one header like this:
|-UPC-|-Description-|-AdType_Week1------|-AdType_Week2------|-AdType_Week3------| 01 banana type abc type def type feg |-Price_Week1-------|-Price_Week2-------|-Price_Week3-------| $97.51 $78.48 $41.45
I have a page where I have 20 textboxes, each indicating a name that I need to go through. Rather than having 20 sets of code, I would rather loop through, something like this:
Code:
[code]....
But it fails to find execute when I hit it, Object reference not set to an instance of an object."
Like many people using ASP.NET MVC, I've implemented my own custom 404 error handling scheme using an approach similar to the one described here: [URL]
(I actually discovered that post after implementing my own solution, but what I came up with is virtually identical.)
However, I ran into one issue I'm not sure how to properly handle. Here's what my 404 action in my ErrorController class looks like:
[Code]....
The part that's different from the answer in the other StackOverflow question I referenced above is how the 'retry loop' is prevented. In other other answer, the code that prevents the retry loop simply sets properties on a ViewModel, which doesn't seem to actually prevent the loop. Since the action is sending back a response code of 404, then accessing the action directly (by typing "/Error/NotFound" in the browser) causes an infinite loop.
So here's my question: Did I miss another, more obvious way to handle the retry loop issue, or is my approach a decent way to do this?
I need to make sure only one checkbox gets checked in a GridView. I have tried a solution on here, but I get an error. The other is looping through the checkboxes in the gridview to get the value, in this case, a date.
I have a calendar control that has a checkbox control added to each cell on dayrender. A user will check the dates that they want to add an event for and click a button that will display the modaldialog box where the user will enter the event for the selected dates. I'm having trouble looping through the calendar dates to get the checkbox contol's checked property.
