I'm using a listbox to save multiple selected value in db. I'm saving that values by seperating comma(,). In edit option i want to reterive the same value from db and want show multiple selected items in listbox.
I have two databound listboxes. The first only shows items that have been assigned to my product. The second listbox shows all available items. What I want to do is select all of the items in listbox 2 that list box one contains.
I have two ListBoxes. I can move items from one list box to the other. I have an Insertcommand for inserting added values from the "ActivePrograms" list box to a db.
my problem is that it inserts only one item when sometimes the user added multiple items.
how do I insert all existing items from "ActivePrograms" list box?:
second issue: how do I make sure the insert command go through the list of items in the listbox and makes sure these rows does mot already exsited in the db? in other words insert only NEW values for that 'Id' value
I'd like to select ListBox Items by using any text. I mean like below For example, Text1.Text = "Item1, Item3, Item5" ListBox's Items are Item1, Item2, Item3, Item4, Item5. Selected ListBox Items will be Item1, Item3 and Item5. Here, I try to find the build-in function that count ',' in any string. How to code?
I have listbox where I am binding values from my database. Now my requirement is when user select values from listbox he/she can select only 4 values from listbox. If user select less than 4 or more than 4 values. I need to show validator that you can select only 4 values. How to achieve this?
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.
Following is the code i tried, but is not working. For some reason, it selects only the last item in the datacolumn.
if (datTableRelatedSchool.Rows.Count == 0) { } else { foreach (DataRow row in datTableRelatedSchool.Rows) { foreach (DataColumn myCol in datTableRelatedSchool.Columns) { lstRelatedSchool.SelectedValue = row["RelatedSchoolPK"].ToString(); } } }
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 ASP.NET 1.1 web application page which is built with .net framework 1.1 and in GridView the data is displayed.I want when they select multiple items then data is updated but without the complete postback of the page.
I'm creating a search form that will include textbox and multi-select listboxes. I figured out how to load the listboxes but not how to grab those values on the postback in the controller method. Here's my simplified code:
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.ComponentModel.DataAnnotations; [code]...
I am persisting the search selection criteria of a listbox onto another page which is called AreasLb. Multiple areas can be selected, I simply want to set the listbox items that the user selected as .Selected = true
I think the below code should work, but it doesn't, with no items in the Listbox being selected.
if (s == "Areas") { string[] area = nv[s].Substring(0, (nv[s].Length - 1)).Split(';'); int i = 0; foreach (ListItem item in AreasLb.Items) { foreach (var s1 in area) { if (s1 == item.Value) { AreasLb.Items[i].Selected = true; } continue; } i = i + 1; } continue; }
I need to have a combo box like this [URL] Upon clicking the dropdown items width should be automatically increased to fully accomodate them. At present, it seems, ASP.Net combo box not supporting this ... I tried applying width attribute using Style.Add to each item.
I am working on a screen where in it has a typical 2 listboxes & 2 buttons(add/remove), so when these buttons are clicked the items have to move from one listbox to another. its all working fine with javascript.but the issue is, I am not able to get the items of the 2nd listbox in the codebehind. I tried with html & asp.net listbox controls. I even tried to access the listbox using Request.Form["ControlName"] - which gives a null value.In the listbox1 the data's are coming from database.The data's choose from listbox1 will be moved to listbox2. And again i have to update this data to one of database table.
i am making use of two listboxes. the data from one listbox is transfered to other listbox on button click, bt teh the data which is selected must be added to the table in the sql server. but it is not storing values it is throwing execption...
private void InsertRecords(StringCollection sc) { SqlConnection conn = new SqlConnection("Data Source=ABCD;Integrated Security=True"); StringBuilder sb = new StringBuilder(string.Empty);
Referring to a C#, .net, System.Web.UI.WebControls.Lisbox which has a multiple select option true and needs to do a postback every time selected index changes.
Problem is, the [SelectedIndex / SelectedItem / SelectedValue] is always on the value of the 1st selected item. Clicking on the second item, third item, does not change the SelectedIndex, causing the listbox to reload and scroll to the highest selected item position.
Is it possible to have 2 ListBox then when a Button is Click the Items is Sorted already to GridView accordingly. btw I have done a sort button but for LB1 only. and LB2 only.
