how to compare to checkbox list and show selected in first checkbox list
[Code]....
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 am binding a checkboxlist with a dataset (with these columns :
id,empname,resourceId,balanceId as columns) with datavaluefield as id and datatextfield as empname;
Now, i want to control the selection of the items. Say some thing like
1. "User should be allowed to check only say 5 items with same resourceId" using javascript
2. And in total he should select only 20 items (max 5 items for same resource id and max 15 items for the remaining)
How can we control this?
I have a situation where I want to show the selected records out of total records for a product of an employee
1) There is a checkbox list bind to <List> of objects from object datasource (For total items in list)
2) Now I want to check the selected items for a particular record in this list
3) For this purpose I have another list of <List> selected items returned by data access layer (For selected items for that employee )
4) How do I bind the selected objects with the total items list ?
5) In spaghetti coding model it was all too easy just by binding the checkbox list with a sql data source and running a for each on form load

how to proceed ?? in this case ??
I have one gridview with two template fields check box and dropdown and my doubt is dropdown validation should occur only for check box selected items..

Using checkboxes, can the row of record(s) be inserted into a database? I am populating a Gridview. Done. A checkbox field has been added, when the user selects one or more rows, a submit button (which is not working) needs to inserting those records into a table. The insert statment will work outside of the page but is not working using the scenario I jut described. Is this task as I have outlined doable?
View 13 RepliesIn VB.net .... I have GridView from which i select list of rows using check box and upon clicking the button i need to display those selected rows in a gridView of another page. and that page is a popup window?
View 1 RepliesI have to select checkboxes besed on group column values. If you see below gridview, column 3 (GroupN) has 1,1,1,1,2,2,2,2....etc (this column data is not static, will change based on page index. i.e PageIndex =2 may starts with 7,7,7,8,8,8,8,8,9,9,9 etc).
Now My question is.
1). If user selected '1', we have to store value and user must and should select another '1' (atleast two times).
2) If user selected '1', and user trying select '2'. Giving error says "Must have select one then one record in group to combine' (will not allow) and unselect '2'.
3) If user selected '1' atleast two times, and user trying select '2'. Will allow.
4) If user selected '1' atleast two times and selected '2' one time, trying to select '3'. will not allow user to select '3'.
I have two Listboxes side by side. First Listbox lists all employee. I have a button to move selected employee from Listbox 1 to Listbox 2. If i select multiple employee from ListBox 1 and click on a button to move to selected employee to ListBox 2, then only alternate selection is moved.
For example.
If ListBox 1 have employee listed as :
1. John
2. Micheal
3. Bryan
After moving to ListBox 2. It shows:
1. John
2. Bryan
My Code is:
protected void btnAdd_Click(object sender, EventArgs e)
{
for (int LItem = 0; LItem < this.ListBox1.Items.Count; LItem++)
{
if (this.ListBox1.Items[LItem].Selected)
{
this.ListBox1.Items[LItem].Selected = false;
this.ListBox2.Items.Add(this.ListBox1.Items[LItem]);
this.ListBox1.Items.Remove(this.ListBox1.Items[LItem]);
}
}
}
}

View 6 RepliesI have a databound grid with a templated field column that is a checkbox. When the user checks the checkbox, it will autopostback and update the row to indicate the box's check state.
My first attempt was to simply use the OnCheckedChanged method, but when this gets called, I have no way to know which row the checkbox came from. Thus, I don't know which row to update.
Can anyone suggest a method to determine which row the checkbox that fired the oncheckedchanged event came from? Or can you suggest a better way to achieve what I need to do?
I cannot bind the checkbox to the data column because I do not want the checkbox disabled in select mode, and do not wish to require the user to enter edit mode to change the value. I also need all rows to be editable. So, the best route seems to be in a templated column.

I have a check box list with some items. I want to make it a single selection. A Radio button list won't work because I need it to allow no selection. It may work if it has allows users to deselect the item selected(like in a check box). The second problem would be that instead of simple text I want a text with link.
