I have to provide "Remove functionality" , listbox is the easiest to provide remove functionality. I cannot modify above record format. If its not possible, then what is the alternate to overcome this issue.
I had used listbox control with multiple selection mode. I stored id with comma delimiter in database.
e.g.
1. List Item One. 2. List Item Two. 3. List Item Three. 4. List Item Four. 5. List Item Five. 6. List Item Six.
Suppose user select item 2, 4 & 6. So I will store it as a 2,4,6 in database. This will work fine.
Now in editing I have to shows selection-bar for item 2, item 4 & item 6. So I had typed below source.
string strData ="2,4,6" if(strData != null) { char[] separator = new char[] { ',' }; string[] strSplitArr = strData.Split(separator); int x = 0; for (x = 0; x < strSplitArr.Length; x++) { // lstWDef_PurchasesEdit.Items[x].Selected = true; lstWDef_PurchasesEdit.SelectedValue = strSplitArr[x].ToString(); } }
But with this statement I got only last item id as a selected item with selectionbar. In our example 2,4,6 only item whoseid is 5 got as a selected item.
if i use
for (x = 0; x < strSplitArr.Length; x++) { if (lstWDef_PurchasesEdit.Items[x].Value == strSplitArr[x]) { lstWDef_PurchasesEdit.Items[x].Selected = true; } }
if the selected items are serial like 2,3,4 then it is displaying correctly..
if items are 2,4,6 then it is not selecting the items of listbox properly.
Is anybody guide me how to make item 2, item 4, item 5 as a selected item ?
I have a listbox. There is an edit button beside it. When users select an item from the listbox and click the edit button, a modal popup extender pops up. The modal popup extender contains a textbox and a button (edit). When they edit the content, they canclick the button again, which will close the modal popup extender and update the text of the selected item.Users want an option to add '<br />' to the item in the listbox, so when the text from the listbox item is displayed in some other page, it shows up in multi-line format. However, when I add '<br />' to the edit text and hit the edit button, I get ajax error that does not close the modal update or edit the text in the listbox. However, if I type in '<>' or just 'br /' in the textbox and click th edit button, it works. In fact any text inside the < and > triggers the error. Here's the error I get.
As a default, there is an item selected on the listbox. But the colour appears blue of the item selected. I want to change the colour of the selected item.
is it possible to select only the item that are displayed in the list box. That is i am having a list of item starting from 0 to 100 in the list box. But i have reduced the height of the list box so that it displayed the item one by one. I need the displayed item to automatically selected.
i want to show the arrayliust items in the listbox, for that i had stored some data in array list, and now i want that if i gv any id which is in the array list its corresponding details are displayed in listbox.

I have a listbox and used the sqldatasource to load the items in the listbox. But if there are no items in the result then i need to hide the listbox and show one msg like "no items". I know to check the listbox is empty or not using "Items.Count " , but which event will i check this?
i have a list box (listbox1) populated with some values.i also have a table with some values.I'd like to show values from table which are NOT IN listbox1.here's a code. I see what the problem is. Just can't understand what is the solution.If I have one value in listbox it works fine, but if more than 1 it messed up, since it tries loop several times.
[Code]....it works fine. The only thing: If I want to update some properties of item, but do not update name(just leave name the way it was) it still fires the validation, and my update cannot pass validation since this name is already exists.i have a listbox populated with values from linqdatasource (or from datacontext using code-behind) Also I have formview which allows to insert new values to database.When I insert new value in the database, this value doesn't show up in listbox until I recompile project/restart browser. When i refresh page nothing happen. Only old values are visible. Id like to have more dynamic page. I tried updatepanels. Maybe I need somehow refresh database connection first?

I have a dataTable that contains a specific column from a database. A listbox contains 100 list items in it. When page loads, I need those listbox items to be selected, whose value matches the value in the datacolumn of the datatable.

if (datTableRelatedSchool.Rows.Count == 0) { } else { foreach (DataRow row in datTableRelatedSchool.Rows) { foreach (DataColumn myCol in datTableRelatedSchool.Columns) { lstRelatedSchool.SelectedValue = row["RelatedSchoolPK"].ToString(); } } }
