Page Created With MultiView - Checkbox Ticked But Disabled
May 24, 2013
My page was created with a multiview which has 3 views.
Now on one of the view I have a checkbox called chkpeer. So, when this checkbox is checked it triggers a submit button to be set to visible and active with the code below;
Code:
Protected Sub chkpeer_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles chkpeer.CheckedChanged
If chkpeer.Checked = True Then
chkpeer.Enabled = True
btnSub.Visible = True
Else
btnSub.Visible = False
End If
End Sub
Now the problem is, when I check chkpeer - btnsub becomes visible set to TRUE. Then when I move to the next View without clicking the submit button then return to the view with chkpeer,
1) chkpeer is still ticked but disabled
2) btnsub visible is SET to FALSE.
I would prefer one of the following
Either have the chkpeer checked - enabled and btnSub still Visible (Ideally)
Or Chkpeer unchecked and enabled so that when I check it again it activates the btnSub ..
I am doing a survey. so basically, i will send out an email with a unique link and the person clicks the link which directs them to my aspx page. that controls i use will be bound to a datatable.
first I will need to show their existing home and email address in a control.
then i will give them 4 checkbox's to tick a certain option. also, how can I ensure only one checkbox is ticked all the time?
I will need the checkboxes to be bound as well, to show the options they chose incase they load the page again after saving.
if i change the code and put checkbox between the <td> tag. when i click the save button, how can i check the ticked checkbox and get the value of the CHECKBOX_1 in cs?
I have 5 gridviews, all of of them have a Checkbox template field. I already did SUM of a specific column in the gridviews and displayed the Total in the gridview footers.
There is a submit button on the page as well.(this is not in a template column in the gridview)
what i do is select some rows in the gridviews by ticking the checkbox. Then I click on the submit button and the values change in the database and page refreshes with the new Total in the gridview footers. Any row that was ticked. the checkbox for that row in the gridview gets disabled. so cannot change the value again.
Now i want a way to show a popup with a SUM of those rows that are ticked recently and the SUM of already ticked and disabled rows before the values change for the ticked rows in the gridview when the submit button is clicked.
Basically when the page runs, if i tick the checkbox it always runs through the "if ticked=false" It always used to work and i cant figure out what i changed.
I'm trying to disable a checkbox depending on whether an xml value contains the word disabled but I'm getting an error as follow. Does anyone know how I can accomplish this or see something wrong with how I'm doing it? The XML value is either blank or contains the word "DISABLED"

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 been using LINQ to SQL for quite a while (about two years). Every thing was fine until now. As usual, I created LINQ to SQL classes and built the project, then created an aspx page. However, I cannot see the DataClassesDataContext in the code behind file. It is not listed in the intellisense list.
I got few check box (depend on settings) that created during run time, some time the number of check box is 3, sometime is 5. And the check box ID also change based on the settings.
How can I search for ALL these check box and return its ID? I do not want to use javascript.
i am desigining an application where i m creating checkBox (not checkBoxList) dynamically. There is one master check box that define group if i click that it should click all subCheck box under it.I am using ajax in my application.i am able to generate check box at runtime but not able to find its event here is the code for creating check box and its event.
//This define master check box

This creates multiple check boxes on the form, and this works fine.
However, in the code behind for my button that the user clicks to execute the form, I cannot figure how how to read the values for the checkboxes. I've tried:
foreach (CheckBox cbxDrive in cbxDrives) { }
but cbxDrives is not recognized.
I need to read through all of the checkboxes to see their values, so that the appropriate actions can be performed in the code behind.
I have created one user control in which I have taken a gridview. Columns of this gridview are getting generated dynamically. (i.e. I read Column name from Xml file) But now I want my first coloumn of this gridview as a checkbox field.
however, on the server side (after postback) I can't read them from the Request Object. How do I "mark" them so I can read them at the postback?
protected void DeleteSelection_Click(object sender, ImageClickEventArgs e) { int multiIdsToDelete = Request.Form["multiCheck"]; <-- In the Future will be added to an array so I can do the delete for each row selected. }
I have creted a checkbox for each column of grid at the top of the header in row created event. I need to check wheather checkbox is checked after button click event.
Im basically listing a set of facilities in a datagrid. Like so:b Projectorcb Laptopcb TelevisonIn roomview, a check appears where a facility is availble in a room. This part works fine.The user can then edit the facilities, by clicking on the check beside each facility. When the update button is pushed I need to record the value of the checkbox, however I cant get the value of the checkbox.eres my codebehind:
I've written some code to scan a directory and write the images to a different view. I'm using buttons with CommandName="NextView" and CommandName="PrevView" to navigate to the following view.
My code to write the images to the different views is called upon the page_load event.
However after clicking the next and previous button this seems to cause a page reload as the images are written to the view again so I end up with duplicate images.
I googled a bit and one of the suggestions was to place the multiview in an contenttemplate and updatepanel but that didn't work either.
Now I've solved the problem by clearing the labels to which the images are written in the page load before the other code fires.
I have a project that is based on a Master Page. I also have user controls that I use as well. Any page that requires scrolling in Design Mode will not scroll. The scroll bar is disabled. I have to switch to Source Mode and then add the text that I need or find the controls that need modified or updated. I have user controls that require scrolling as well but they work just fine. Only the pages tied to the master page. This is very annoying and only happens on certain projects.
I have a checkbox on my page that must be ticked and to validate it I am using a custom method as below. The problem is that I now put the checkbox and method within a Create User Wizard custom tempalte and when I submit the form it does not activate the validation check. If I put a normal button on the page outside the tempalte it works. Not sure If I a missing something. Perhaps I can activate it in Created User Event handler in code behind. All Button in my create user Event.

I've been looking for the best method to add "Tab Views" to my .ASPX web pages. I read about one method on the internet and actually remembered the other possible method from a control in the default VS2010 toolkit.
I like the <asp:MultiView> control because its so easy to use. The only thing is that it requires the page to be posted back. The second method would use CSS + JavaScript to essentially emulate tabbed views in the same webpage by changing the styles of <div> elements based upon the users tab selection, making the selected tab appear visible and the other tabs appear invisible.
I like the ease of implementation of the <asp:MultiView> but I dislike the fact that it requires the page to be posted back and resent. Also, I haven't even tried this myself yet but Im assuming there is a way to setup the page to make it look like you can select different tabs with a MultiView. Can anyone confirm this?
I like the CSS+JavaScript method of "Tab Views" because no page postback is required but it is a little more work to code. No big deal really though once its done.
