To Checked CheckBoxList item I am using following code

C#

string pyDetails = objBiltyDetails.BltPayDetails.ToString();
            string[] split = pyDetails.Split(',');
            foreach (string item in split)
            {

                //if (item != "")
                //{

                    CheckBxPayDetails.SelectedValue = item;

                //}
            }

There are two values in item but only one check box is Checked. Please help

Solution 1

Yes obviously the last item in the enumeration will be set as SelectedValue because that's what you have coded.

If you are trying to select all checkboxes under the CheckBoxList, then try the below line of code in your foreach loop:

CheckBxPayDetails.Items.Add(new ListItem() { Text = item, Selected = true });

It is CheckBoxList

Please see my updated answer.

Reason for my vote of one: If you look at the specification for CheckedListBox, you will find that multiple selections are not supported, so even your revised answer (which adds new items every time it is used, rather than selects existing ones and is thus a bit odd) cannot work! Please, check your answers before you post them! See MSDN: http://msdn.microsoft.com/en-us/library/system.windows.forms.checkedlistbox.selectionmode.aspx

Sir! It's not CheckedListBox as you said. As the Anjutlya said this is a CheckBoxList.
Further the control you are mentioning is part of WinForms not asp.net (the question is tagged to ASP.net).
Don't be in hurry to downvote somebody just because they have different views.

Yes its true, Rakesh sir I am using CheckBoxList in asp.net But I am not trying to add item I am trying to Checked items.

RakeshMeena 9-Jun-11 3:59am

The code is adding checked items (checkboxes) only since we are setting "Selected" property. Please try and let me know the issue (in detail).

OriginalGriff 9-Jun-11 3:49am

I noticed that myself, and changed my vote - you may have noticed. I was not in a hurry to downvote "because they have different views" - I rarely do downvote, but normally when an answer is wrong and untested. In this case, I made a mistake, have corrected it, and apologise. You were posting your comment as I was posting mine!

OriginalGriff 9-Jun-11 3:46am

Reason for my vote change to 5: Sorry - I made a mistake and was referring to a CheckedBoxList (winforms) rather than a CheckBoxList (web) - Select does indeed work on the later so some of your answer was correct. Please accept my apologies.

RakeshMeena 9-Jun-11 3:51am

No issues. Thanks anyways.

Please ignore this answer - I assumed CheckedBoxList rather than CheckBoxList.

If you look at the specification for CheckedBoxList you will see that MultiSelection is not supported, so it isn't going to work anyway. Even if you did use code that might select two items, such as

CheckBxPayDetails.SelectedItems.Add(item);
(Which as I said, won't work because CheckedBoxList doesn't support multiple selections.

Are you sure you want to use Select? Or are you trying to use Checked?

"I am trying to checked"

Try:

string pyDetails = objBiltyDetails.BltPayDetails.ToString(); string[] split = pyDetails.Split(','); foreach (string item in split) { int index = CheckBxPayDetails.FindString(item); if (index >= 0) { CheckBxPayDetails.SetItemChecked(index, true); } }
You may want to loop through them all first, setting the check status to false - I don't know what you app does!
