I have successfully implemented article - "Print only the items which are selected using checkbox in a ASP.Net DataList control"
I would like to add a dropdownlist above the DataList Control to filter the contents of Datalist and then print the items selected using Checkbox in a ASP.NET DataList Control.
I am trying to put the select command in code behind:
sdsAdd.SelectCommand = String.Format("SELECT Classes.ClassId, Committed, CallNumber, SubjectArea, CourseNumber, SectionNumber, GradingBasis, NumberOfUnits, NetId FROM Classes INNER JOIN EnrollmentAdjustmentClasses ON EnrollmentAdjustmentClasses.ClassId=Classes.ClassId WHERE AllFormsId='4' AND SectionId='1' AND NetId=@NetId AND Committed='True' AND EnrollmentAdjustmentClasses.FormId={0}", Request.QueryString["FormId"].ToInteger32()); gvAdd.DataBind();
When I do that, then click edit to edit the selected item, the item disappears from my gvadd. What am I doing wrong?
I have 2 ListBoxes. 1st SelectionMode is Multiple. Once I select many options from 1st ListBox I can copy it in ListBox2 but i Unable to remove it.
Code :
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click For i = 0 To ListBox1.SelectedItems.Count - 1 ListBox2.Items.Add(ListBox1.SelectedItems(i).ToString()) ' ListBox1.Items.Remove(ListBox1.SelectedItems(i).ToString()) it is not removing. Next End Sub
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);
I need to charge my checkboxlist1 from database, eg load fruits and vegetables. When selecting fruits, new filter based on the previous selection in my checkboxlist2. for specific search.
I have a ListBox which is bound to a list of data items.
Now I want the user to be able to filter the items shown in the ListBox based on the search expression typed in the TextBox. For each character typed in the TextBox, the ListBox items should change to show only the items matching the search expression.
I'm having trouble getting selected items in a listbox to be seen as selected. On my aspx page there's a listbox and a button:
[Code]....
But if I change my condition to Not selected, the string does build, with every item in the list. So the Sub is reached, the items and their text and values are seen, but user selection of items doesn't work. What am I missing?
I have a list box which is populated using a dictioanry. When I iterate throught the selected items using the following code, it always show only the first items as selected - even if the first item is not selected. Have you ever encountered this scenario? This problem occurs when I use dictionary for binding. On the other hand a generic list works fine.
my vb.net will not use listbox1.selecteditems it always comes up with a blue line underneath even though when i search online everyone is using this. my goal is to get the selected items and list them in a textbox
Protected Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim li As ListItem For Each li In ListBox1.Items If li.Selected Then TextBox1.Text &= li.Text & vbCrLf End If UpdatePanel2.Update() Next End Sub End Class
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 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 asked myself if there is an easy way to check if a ListBox has a maximum of 5 selected items. There must be at least one and at most 5 items selected.Do i need a CustomValidator with server-side validation?
i have a listbox LbGeneratedExcelLinks when i click inside of it on an item it download the selected item
here s my code
Protected Sub LbGeneratedExcelLinks_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles LbGeneratedExcelLinks.SelectedIndexChanged Dim RedirectUrl As String = LbGeneratedExcelLinks.SelectedValue Response.Redirect(RedirectUrl) LbGeneratedExcelLinks.SelectedIndex = Nothing End Sub
problem is if i want to click on another button or other event it keeps showing the dialog open or save file the one i put inside selectedindexChanged
unselect after the selectedindexchanged i think it will solve my problem
I added some food items in CHeckBoxList. I want to add selected food item(s) in a ListBox. The Text Property is name of the food and it's value is there Price (Food Price) As soon as I add any food item in a ListBox the total should be displayed.
Whichever code I wrote using it, if i select 1 item then it adds in a ListBox. But If I select another food item then Previous food item also added because it is selected. I will select some food items then it will be adding in the ListBox, I will check the total, if the total is greater than my budget then i can remove some food items.
I have a DropDownList shows the company names and a ListBox shows the products of the company I selected in the DropDownList and I can select many products from ListBox:
