Combo Box With Hidden Values?
Nov 10, 2010
I have a combo box that is tied to a binding source that loads a list of users from a table. Currently the list of users is a List of String object type. When a user selects one of the users from the drop down, a list is filtered down based on the selection. To do that I currently have to requery the User Table to grab the UserID column of the user selected, which seems a bit inefficient to me.
Is there a way that I can assign a custom object with two properties (UserName, UserID) and have only the User Name is displayed and when I have to filter the list, I already have the UserID, so there is no need to requery the database.

I've got some code like the following. I want it so that when I chose an item in 'select 1' it changes the in the second combo box but I'm not sure of the best way to go about it. Does it have to be AJax or can it be done with just Javascript?

Having come from the MS Access IDE, I have used hidden text boxes to store information needed on a given form. Often they are data-bound and the program needs to reference the data but the end user does not need to, or should not, see them.
I am very surprised to find that in .NET, you cannot do this. Making a control visible=false should be a UI decision, but the value should still be programaticaly available. Am I just missing something, or is this truly a limitation in .NET?

I am using asp.net.I have taken one Hidden value and assigning value to that hidden variable in Java-script.
aspx: <input type="hidden" runat="server" id="hdnProductionIds" value="0" name="hdnProductionIds" />
JS:document.getElementById("ctl00_ContentPlaceHolder1_hdnProductionIds").value = "123";
I want to use that hidden value in server side coding(vb.net). But while do-post back, hidden variable value becomes Zero (default value)

<tr>
<td align="right"></td>
<td align="left">
<input name="userId" value="8194364" type="hidden">
<input name="action" value="saveChanges" type="hidden">
<input class="submitImage" src="/theme/default/buttonSaveChanges.gif" type="image" align="top"><input class="submitButton" value="Save Changes" type="submit"></td>
</tr>

Again the code clicks the button, but doesn't save the information so I figured it has something to do with the hidden value. I've never seen this problem before so I don't know where to go from here.

Right now I am using this code on client side.
[Code]...
The values for the hidden fields are already set. I want these value to open a window, in which the fields will be already filled using the values passed by this page. This code is working fine on Internet Explorer, but not on other browsers. Moreover, when I don't pass any value and just open the required window, it works on all browsers.

I am familiar with getting a selected value from a combo box but what about if you wanted to get all the values from a combo box then store those values in an array or list. The combo box would be data bound to a source and have an ID as the value member. So How would I get all the values from the combo box.

I have two comboboxes in my form (cbAdresse & cbVerwaltung). Choosing the value in the first combo, i get the value from the table into the textbox txtAdID.

So i use the following code for the SQL Compact Client:[code]Using this code i get the following value in my combo cbVerwaltung: "System.Data.DataViewManagerListItemTypeDescriptor".[code]

I am working with Vb.net and have a form with a combo Box. On load the form is loaded with one of the following details depending on what is stored in the database; Cancelled, Processed and Failed.
TxtColStage.Items.Add("Cancelled")
TxtColStage.Items.Add("Processed")
TxtColStage.Items.Add("Failed")
Then I have an update button and when the user drops down the list he/she can select between Cancelled/Processed/Failed. I want to be able to grey out or disable Processed and Failed, so that when the user updates the field he/she can ONLY update with the Cancelled option ONLY.

I've used VB to connect to Excel and get the titles of the different columns in a spreadsheet. These then display in a drop down combo box for the user to choose from. I'm getting lots of empty values in my combo box because not all the columns in Excel have titles. How would I go about telling it not to display them?
Excuse the easy question but I've only started learning to code a week ago.

I'm using the combo box control in VB.It is not bound to a data source.Visual Studio gave me a text box to enter the values for the combo box.When I run the program, there is a blank value?How do I eliminate this blank (or null) combo value? My combo box is a required field.
For example I entered
Option 1
Option 2
Option 3
When the program is ran, the combo box has <blank> (which is selected) Option 1

I have a few combo boxes that need to be loaded up once and displayed multiple times (whenever the main form is opened) The reason for this is because it's taking about 10 seconds for the form to load each time it's opened due to unnecessary re-querying.
Here is an example of what I have as a combo box source and what I've done.
I've put the query, connection, etc... in a module and call it on the login form - i don't get any errors but the data does not load into the combos.
'In Module
sql = "SELECT DIR_ID, DIR_NM FROM LTC_FBS_DIR ORDER BY DIR_NM ASC"
RConStr = String.Format(RConStrFormat, LoginForm.txtUser.Text,

i have a form with 3 combo boxes. The value of the combo boxes generates a sql query with 3 parameters. The sql generates a RDLC report.
For example:
Combox1 with values(v1,v2,v3,ALL)
Combox2 with values(v1,v2,ALL)
Combox3 with values(v1,v2,v3,4,ALL)
Me.ExampleTableAdapter.QueryWithParams(Me.ExampleDataSet.Table, Combobox1.SelectedIndex, Combobox2.SelectedIndex,Combobox1.SelectedIndex)
QueryWithParams:SELECT * FROM Table WHERE Column1=@c1 AND Column2=@c2 AND Column3=@c3 Ok the problem is when the selected value is ALL in the combo X, i cannot get the values because i must change the query and kick out the parameter.For example:If the combo1,combo2,combo3 have the values ALL. I don't need parameters.SELECT * FROM Table IF the combo1 is ALL.SELECT * FROM Table WHERE Column2=@c2 AND Column3=@c3 If combo1 and combo3 are ALL SELECT* FROM Table WHERE Column2=@c2 Then in code I look which is the selected value of the combo and upon it i do the query.Is there a way that i do this thing without generating all 8 types of queries?PS. I cannot use stored procedures because i'm using SQL Server Compact

I want to insert data to a table in SQL DB.I have a combo box with the values "5" and "6". When you click one or the other in the combo box i want these values to be inserted in a database( MS SQL Server 2008).I also have some textboxes which are bind correnctly and have no problem. The problem is with the bindings(i guess) of the combo box. I get sql exception.
Here is a snippet.
Private Sub BindFields()
txtSurname.DataBindings.Add("Text", ObjDataView, "surname")
txtName.DataBindings.Add("Text", ObjDataView, "name")

As some of you probably already know I'm currently creating a ticket ordering system. I'm having some slight trouble getting one of the key elements of the application to work mainly because I'm not sure where to start with it.
I currently have a form with two combo boxes (one for the origin of the journey and one for the destination). The idea is that the customer tells the employee over the phone where their journey begins and ends. They will also select a date of travel - but the date of travel doesn't really matter to much at this time.
Once a to and from is selecting from each combo box, the price will be shown in a label on the same form.
I have the to, from and prices information in an Access database table and my database is already linked to my application using a data connection.
trying to get to price to display when the two values in the combo box are selected?
