Mar 19, 2013
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 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 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:
CheckedListBox1.DataSource=ds.Table[0]; CheckedListBox1.DisplayMember="Name"; CheckedListBox1.ValueMember="ID"; [intelligence Not Shown in VS But Its working fine for me].
now i want To Find out The Selected Item value in checkedListBox.
below is the code I have but I want to change the ddl.Deal(dropdownlist) to cbl.Deal(checkboxlist).. How can I loop throught each items if checked. and if all items are checked. to filter my data and show in gridview..
protected void btn_Click(object sender, EventArgs e) { myAPI.myWeb myAPI = new myAPI.myWeb(); myAPI.SearchParameters sSearchParameters = new myAPI.SearchParameters();
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 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 gridview and users would select some records and would click on the submit button and i will be saving those records into database using a stored proc.... now .... just below the gridview and above the submit button there are few checkboxes by default they wud be checked. How would i save the selected values and the checked boxes in database i wrote the stored proc for the gridview but how would i save the checked checkboxes into the same table.
For i As Integer = 0 To gvSelectScreen.Rows.Count - 1 Dim chkTemp As CheckBox = TryCast(gvSelectScreen.Rows(i).FindControl("cbStatus"), CheckBox) If chkTemp.Checked Then ContractNumber = gvSelectScreen.Rows(i).Cells(0).Text ClientProgramNumber = gvSelectScreen.Rows(i).Cells(1).Text ClientProgramName = gvSelectScreen.Rows(i).Cells(2).Text StartDate = CType(gvSelectScreen.Rows(i).FindControl("txtStartDate"), TextBox).Text EndDate = gvSelectScreen.Rows(i).Cells(5).Text Dim connStr As String = ConfigurationManager.ConnectionStrings("MainConnectionString").ConnectionString Dim myCon As New SqlConnection(connStr) Dim cmd As New SqlCommand("usp_ParametersFromGrid") Dim dt As New DataTable cmd.CommandType = CommandType.StoredProcedure cmd.Parameters.Add("@ContractNumber", SqlDbType.VarChar, 22).Value = ContractNumber.ToString() cmd.Parameters.Add("@ClientProgramNumber", SqlDbType.VarChar, 22).Value = ClientProgramNumber.ToString() cmd.Parameters.Add("@ClientProgramName", SqlDbType.VarChar, 100).Value = ClientProgramName.ToString() cmd.Parameters.Add("@StartDate", SqlDbType.VarChar, 20).Value = StartDate.ToString() cmd.Parameters.Add("@EndDate", SqlDbType.VarChar, 20).Value = EndDate.ToString() cmd.Parameters.Add("@RequestID", SqlDbType.VarChar, 50).Value = RequestID.ToString() cmd.Connection = myCon myCon.Open() cmd.ExecuteNonQuery() myCon.Close() End If

I have the following code which simply gets data from a table and populates the questions_lb listbox with items. I have a button on the page, which when clicked, should write (on submit) the selected state of each of the items. The code below writes the text values of each of the items fine however it always writes the li.Selected as False even though i have selected items from the list. Note that you can select Multiple items from the list. Does anyone have a clue why its not writing 'True' for an item that is selected on submit?
How to get the selected item from the listbox in the selected index changed event. I tried: Label1.Text = ListBox1.SelectedItem.Text; It is giving me object set to null reference.
foreach (ListItem item in ListBox1.Items) { if (item.Selected) { //lblResults.Text += item.Text + " "; Label1.Text = item.Text; } }
