Select Multiple Values In DropdownList In Asp.net With VB?
Jan 20, 2012
I am creating a page in which I need to show a drop down List. From this drop down List a user can select multiple values. I know I could use a check box list like:
but if there are more than 50 or so values then that will consume a lot of space on the page and will look odd. So kindly tell me how can I select multiple values from drop down list or if there any alternatives so that I can select multiple values and show many records on a minimum space but not a grid?
i used the following technique to Select multiple items from DropDownList into TextBox with No duplicates, however i dont think it is the most proper way,
pressing again with same value selected choose another value from DDL and press button
here is my code Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click If TextBox2.Text.Contains(DropDownList1.SelectedItem.Text) Then
In ASP.NET MVC, is it possible to fill the list of values of a Html.DropDownList from multiple data sources along with multiple manually entered values?Basically, I envision it being formated like the below using something along the lines of OPTGROUP:
I've thought about using a view on the DB and getting the data from that, however, I've not really the faintest how to lay it out like above using helpers and to pass the data to it from multiple sources.
I have three dropdownlist which values are to be inserted in one particular field in the database. But i am new to ASP.
This are my following codes: Dim strConn = ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString Dim myConn As New SqlConnection(strConn)
I have a javascript function below to move from select multiple box A which is populated from database to another multiple select box B, in the event of a postback my values in B which are moved over from A got lost. Initially I thought because I included a "runat="server"" tag for server side actions but apparently it's not the case. I read about Form.Request but ain't have a clue how to go about it. I just need to retain those values in multiple select box B.[code]...
I have a little challenge. I have a report that I declared a parameter called Department that has default values like this: [Code] The problem is that when I test this (with CR10 or on web), and I select multiple values, the thing does not show the values for the multiple values. It only works when I select a single department. What should I do?
I am almost there but for some reason I don't find the answer to my issue. Here it goes. In my application I have a form which displays a data grid view with some info I get through XML from a web server. The data grid view have as first column a Check Box colum. The second column have the information I get into a variable (from cells), one by one, to pass it to the sub with the XML command.
What I want to do is to be able to select all the rows and send the cell info of the second row (only for the selected rows) to my sub which will execute once then send the second cell info and execute the sub and so on until all the loop is complete. Currently my code works only if I delete one row at a time (sending the XML code will delete the info in the web server and update the datagridview which in return will remove the item).
Trying to select a dropdownlist item based on a value
Dim basedate As Date basedate = "12/30/1899" Label26.Text = basedate.AddDays(y) ddate.SelectedIndex = ddate.Items.IndexOf(ddate.Items.FindByValue(Label26.Text))
I want to make my dropdownlist selected first value "--select--" when first load page as i need to force user to choose an event from list. I am blur since I need to perform other function at page_load to check checkbox enable properties, so that I not sure where should I put the coding to Add empty value to dropdownlist.
I did put the following code in page load but nothing happen, the "-select- also no appear in the dropdownlist.
Seems most of the examples I find are c#, so in some cases I'm left scratching my head... to make a long story short, I'm simply trying to output the selectList of items to a drop-down within my view:
My ViewModel: Imports System.Web Imports Whitebox.UI Namespace ViewModels
[Code]...
All I'm trying to do now is simply output my "SelectList" within a HTML.DROPDOWNLIST() in my view.When doing a step through, my list items are showing within my "Return view(viewmodel)" watch, but I'm stuck with performing the output.
I have a DropDownList control and I want to set the SelectedValue to the lowest value in the dropdownlist greater than 0 for example my control drpExample has the following values:[code]I want to use drpExample.SelectedValue = The lowest value greater than 0..The SelectedValue should then be 0.90..Is there a simple way to do this?
I'm working on a webpage automation project. And I am very new in this. I want to use Webbrowser control to select an item in the dropdownlist. Now,how do I programmatically select an item from the HTML snippet below. I would like to select, say for example, "2009" from this
HTML code: <select name = "yr"> <option value= "">Year</option> <option>2009</option> <option>2010</option> <option>2011</option> <option>2012</option> </select>
I am trying the following code : For Each element As HtmlElement In WebBrowser1.Document.GetElementsByTagName("select") If element.GetAttribute("name") = "yr" Then element.SetAttribute("value", "2011") End If Next
I have an application to display the records of the customers. I am using the wizard to do the edit and delete of the records. In one of my column consists of dropdownlist. When I wanted to edit the changes by selecting the dropdownlist, it didn't display anything after I selected the changes. I have to make changes because my friend did not finish up this part which selecting the selected item to make the editing of the records.
I have a web project in asp.net in which i have dashboard on which there are dropdownlists with previous seven dates and when i select the date from dropdownlist it opens the file from folder matching with date selected.My dropdownlists are arranged vertically.A strange problem is that when i select the date from ist dropdownlist it opens the file fine and when i select the date date value from any other dropdownlist it opens the same file which opened from the ist dropdownlist all remaining dropdowlists behave same like.And other strange Problem is that when i start opening files from the last dropdownlist to ist.
I have an asp drowndownlist and I'd like to change its selection after a button click. I can't seem to find a way to do this, is there a way? (Its a reset button of sorts, and I would like the dropdownlist to return to the "default" value.)
I am trying to do is select a value from a dropdownlist (ddlname), hit submit (Where the problem lies) and place the results in the redirected page that carries the value in a querystring. I am under the impression that if you want to pass more then one value you use the concatenation symbol "&", correct? If not what is it? (Using '+' doesn't work neither, just thought I would try it for the same of ruling that issue out

i have problem for the drop down list in the grid view, it not fire the select index changed. I bind the data for the drop down list when the row databound. But when i select the data, it not fire the select index changed. Another drop down list which hard code the item list fired the select index changed. Below is the code behind and the front end code.
I have a dropdownlist that is bound from a separate dropdownlist selected value, on a second page. The number should read "563000" but instead when the list populates it reads.
i am trying to bind a dropDownList control to a select query that has a parameter.the query itself runs fine on sqlserver database when the paramter is replaced with an actual datetime variable.the basic query is: SELECT DISTINCT DeliveryZone FROM dbo.tblComplaints WHERE (DeliveryZone IS NOT NULL)AND (DeliveryZone NOT IN ('**', '??', 'EE', 'T', 'M'))[code]
I'm running into a little problem with a gridview and a dropdownlist. I can get the dropdownlist to load initially, but when it autopostback's it returns with no value. I am populating the dropdownlist in the RowEditing sub. I'm guessing that I must somehow rebind in the RowDataBound sub, but don't know how to go about it. If I try to find the control's SelectedValue I end up with nothing.
VB Code

I would like to disable a specific items from DropDownList. I have below code but it does not working. DropDownList have 5 items.And,I'm getting error:Index was out of range. Must be non-negative and less than the size of the collection.Parameter name: index
Protected Sub CheckBox1_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged Dim X As Integer = 0 <> 1 DropDownList1.Items(X).Enabled = False End Sub
But, if I add a different value for X, then it disable 1st and 2nd item.
Protected Sub CheckBox1_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged Dim X As Integer = 0 or 1 DropDownList1.Items(X).Enabled = False End Sub
My goal is if I would have a 365 items in DropwDownList to disable items for example between 120 and 150.
This is my code and i am getting an error ..Cannot have multiple items selected in a DropDownList. when the page loads it select "ALL" in DDLModality but when i change DDLModality.selectedvalue to any "value" then no error but again when i change to "ALL "getting the error.
onchange of DDLMODALITY submit the form form1.target = ""; form1.action = ""; form1.submit();
When I click on button1, employee_id and P values need to be transferred from button1_click to Cal_Category13() and go through all the calculation. After the calculation, udtnew.X and udtnew.MTD values need to be transferred back to button1_Click
I've no problem to return multiple values Cal_Category13().MTD and Cal_Category13().X from Cal_Category13() to button1_Click but i've no idea how to transfer employee_id and p values from button1_click to Cal_Category13().

I'm trying to create an option to select a specific entry in a SQL table if multiples exists. The Sub listed below is for a textbox (MOTxt) and a button (GotMO) for checking an MO# to pull from SQL. Based on the number entered, will populate other text boxes on the page with that row's data. There are exceptions to this, where the MONumber will be entered more than once with different data associated with each entry. So, here's my situation. If we have a duplicate MONumber listed in the table, it will populate the textboxes with the first entry it finds for an update.I would like to create a dynamic dropdownlist (that displays only if multiples are found) displaying the 'Name' field entries for each MONumber found, then once the correct name is selected from that list, to then populate the textboxes with that selected datarow.Here's my code behind:
Protected Sub GotMONum_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles GotMO.Click Dim da As New SqlDataAdapter
I have a question regarding the dataset usage in Reporting Services. I have a stored procedure which returns multiple select statements (result tables), and I created a Dataset in Reporting Services 2005 with this stored procedure. The problem is that I can not reference the second or third result table, and I can only use the first select statement fields. Is this the limitation on Reporting Services Dataset or is there a way to use multiple table results in one dataset?
I have a webbrowser control in VB 2010 Windows Form project that loads a webpage. This webpage contains select tags with a few options. I can select one option using:
Dim cboTemp1 As mshtml.HTMLSelectElement
[Code]....
But I need to be able to select more than one option (e.g. 1 and 6) in the select tag/element. Is that possible, the Select element has the multiple select option enabled..
