I made some adding of dynamic checkbox and it would be located in the panel. And at the same time the checkbox would be save also in my List(Of Checkbox).
BTW, my checkbox is not the HTML control (if that's how you call it). Now i made some function wherein Im going to get all the state of my checkbox in that particular panel. This is how I do it:
Code:
For Each ctrl As Checkbox In listControl
if ctrl.checked = true then
' code here
end if
Next
Unfortunately nothing happen. So how am I going to check the state of my checkbox. I already test all the checkbox saved in my list(of T) and also tried looping "Me.pnlControl.COntrols"
I'm using visual web developer express 2005in VB language:how can i determine wat item/s is check in a repeater with checkbox?here is sample of my repeater:
[Code]....
here is a sample image of this code in running mode:how can i know all rows that are checked in my repeater and how to determine its values?another thing is that after i determine the checked row, how can i create a singleselectcommand for those selected items?
I am trying to determine if the user selected a checkbox for each row in a ListView after hitting a submit button. If so, I need to get the record ID and one other piece of information from that row to insert their selection into a table. I would use a GridView but the questions must be grouped by their categories with the category names displayed followed by their corresponding questions (from what I've read ListView makes this easier).
I tried the code in this forum posting

The problem I am encountering so far is that it keeps returning null even if the Checkbox is checked.
Here is my code:
foreach (ListViewDataItem lvi in lvQuestions.Items) { // Find the checkbox in each row CheckBox cb = (CheckBox)lvQuestions.FindControl("cbQuestion"); // If the checkbox is ticked
Ok so I am working on a control that when the user comes from a specific website then it will be a certain action. What would be the easiest way to do this?
Bit confused about this. I was under the impression that if you added server controls to the ItemTemplate of a repeater then the ID's assigned to those controls would persist across postbacks and the state would be maintained. But it doesn't seem to be happening. Here's my ItemTemplate:
[Code]....
Which populates fine. What I'm looking to happen is for the user to be able to select certain items from the repeater using the checkbox and "process" them (i.e. perform some data operations on those items) on clicking a button which is outside the repeater. Here's my button click code:
[Code]....
But if you step through this, the checkboxes are found and assigned correctly but their Checked attribute is always False.
Suppose I have created a spgridview with the following code.

To persist the checkbox states between pagebacks ,currently i am using session states.It has some draw backs.Now how can I persist the checked states,when the user manually checks all the checkboxes,how can i make a check on the header checkbox?
I am learning how to use profiles. My profile properties are defined in web.config and wish to add selected checkboxlist values to user profiles.TextBoxes and RadioButtonLists all seem to work fine, but not my CheckBoxList values.How do I go about making this work?
while comeing back from page2 to page1 I need to load the checkboxes in the same state when the page navigated from Page1 to page2.Below is the code that I have written.All the loops and conditions get executed as expected,but when the page loads all the checkboxes are unchecked,even thouse which were checked.I am not able to understand why the code is not giving the expected result?
I know how to keep track of the checkbox in a datarow, but I got no idea on keep tracking the checkbox state in the header rows.
For example, assume my gridview have 3 pages, after I check the checkbox in the header rows in 1st page, I click on 2nd or 3rd pages, and click back to my 1st page, my checkbox status in 1st page still remains checked.
I have searched and searched and unable to find an easy to understand answer with a sample of what I am after. Apologies I am new to ASP and programming VB.
I have a usercontrol with an asp.net checkbox in it. I'm attempting to write a jquery script to convert that normal checkbox into a three-state checkbox. The states are 'checked', 'unchecked', and 'intermediate'. Clicking on an intermediate state should change the state to checked, clicking on an unchecked state should change the state to checked, and clicking on the checked state should change the state to unchecked. My idea was to be able to insert a normal asp.net checkbox into the page and then call the jquery function to make it three-state.
Here's my jquery function, which is rough but working:
function SetTriStateCheckBox(checkboxfinder, initialval, originalCkbxUniqueID) { var i = 0; var chks = $(checkboxfinder); if (initialval){ chks.val(initialval); } chks.hide().each(function() { var img = $('<img class="tristate_image" src="../Images/tristateimages/' + $(this).val() + '.gif" />'); $(this).attr("checked", ($(this).val()=="unchecked"?"false":"true")); $(this).attr("name", "input" + i + "image" + i); img.attr("name", "" + i + "image" + i); i++; $(this).before(img); }); $(".tristate_image").click(function() { t = $("[name='input" + $(this).attr("name") + "']"); var tval = t.val(); $(this).attr("src", "../Images/tristateimages/" + (tval=="checked" ? "unchecked" : "checked") + ".gif"); switch (tval) { case "unchecked": t.val("checked").attr("checked", "true"); break; case "intermediate": t.val("checked").attr("checked", "true"); break; case "checked": t.val("unchecked").removeAttr("checked"); } setTimeout('__doPostBack('' + originalCkbxUniqueID + '','')', 0); }); }
Here's a simplified version of my OnPreRender event handler which registers a startup script:
Everything seems to work correctly, except that I'm not hitting the event handler of the original checkbox when I post back, after clicking my newly inserted image. It does hit Page_Load. If I take out the .hide() part of the jquery, and click on the original checkbox, Request.Params['__EVENTTARGET'] is the same as when clicking the newly inserted image.
I've created a visual webpart .My user control is gridview,in which one of the column is checkbox.The checked state of my checkbox within a gridview get disappeared during postbacks. I want to maintain the checked state.
I've a checkbox with autopostback=true. If i check the checkbox the postback occurs and changes a label text. But if i click back in the browser the checkbox is not returning to its previous unchecked state. How can i bring back its state?
Can i write some JavaScript to persist the state of a control?
I am using pagination on datalist control. It is working fine without any issues. But I am not able to maintain the checkbox state while doing pagination. Looking for appropriate code for maintaining the state of checkbox.
I in page load i change the checkstate of checkbox false to true or true to false, in turn which i expect to fire the check_change state but seems not firing the event
protected void Page_Load(object sender, EventArgs e) { chkDegisim.Checked = true; chkDegisim.Checked = false; } protected void chkDegisim_CheckedChanged(object sender, EventArgs e) { int a = 1; } when i put a breakpoint to chkDegisim_CheckedChanged, it does not fall into the event chkDegisim_CheckedChanged. chkDegisim's autopostback is true and i have declered chkDegisim_CheckedChanged event in aspx.
why it does not fire chkDegisim_CheckedChanged event?
I have a multiView control within which I have 3 views as part of building a customer order.
Step 1: Customer is selected from gridView and Customer Name is saved in MultiView Session.
Step 2: Products are chosen from gridView. The grid is re-bound depending on which product category is selected in a dropDownList. The product details are also stored.
Step 3: All of the details required to build the INSERT query are passed to labels on a form to be reviewed before committing to db. The next stage, now that I have managed to select multiple rows, will be to display this data in another gridView.
Everything works fine, except for the paging and dropDownList which is causing the checkbox state to be lost after postBack.
I've read a few articles on this, but I think I have made the task more complicated due to the dropDownList in addition to paging. Essentially the customer will be able to select various product lines, across various bindings of the gridView so I need to persist the checkbox state and retain the data for the INSERT query.
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.
