i have a dropdownlist in aspx (vb.net) that i have 2 dropdownlists. i want to show the second dropdownlist based on the value of first one. they are data wise interconnected, so if after selecting a certain record in first, if the second one has more than one record, the dropdownlist should be visible, else it should remain hidden. am sure this can be done with javascript, but i just dont know how.
View 4 RepliesI have a page which is used to display numerous forms for the user to fill out and get reports generated. Each of these forms is inside it's own ASP:Panel control so that I can toggle the visibility of the form (so that only those with appropriate permissions get access to the reports they are allowed to).
The client has now requested a "table of contents" like area on the page with hyperlinks pointing to each of the forms (so that they don't have to spend time scrolling the page to find the particular report form they want). This is easy to accomplish using standard <a href="#Area"> and <a id="Area"> tags. What I am now looking for is a way that would allow me to hide the links of reports that the user does not have access to.
I was first thinking of using the ASP:LinkButton control, but I do not want any postbacks to occur from clicking the links (that would be very unnecessary). Are there any other methods I could use to accomplish the same goal? I am looking for something which would make it easy for me to toggle the visibility of the corresponding link at the same time I am toggling the visibility of the panels containing the report forms (done now from the code-behind).
I have a jQuery 'toggle' function on a table that I am using in conjunction with an asp.net gridview. I have pagination on my gridview and when I click on the next page, it posts back and therefore closes the Toggle/Table - I need a way of keeping it open. I have had a similar issue in the past with the Accordion function but resolved it via this method
<asp:HiddenField ID="hidAccordionIndex" runat="server" Value="0" />
<script language="javascript" type="text/javascript">
$(function () {

I have a dropdownlist that is populated by a webservice using the ajax cascading dropdown. I have not been able to set the selected value using javascript. It appears that the values do not exist when the javascript runs. I placed the javascript at the bottom of the aspx page. Here is all of the code and the javascript I have tried.
<asp:DropDownList ID="ddlBusinessArea" runat="server"></asp:DropDownList>
<cc1:CascadingDropDown ID="CascadingDropDown1" runat="server" TargetControlID="ddlBusinessArea"

I need to get the ID of a dropdownlist (ASP.Net Control) So that I can tell if an item has been selected.
Right now I am trying to just write the count of the dropdownlist to an alert box as follows:
OnClientClick="alert(document.getElementID('<%=ListBox1.ClientID %>').options.length)
The error I get is 'document required.'
I want to be able to change an image depending on what is selected in the drop down box. I have this JS code to change the image. Simplified of course.
<script type="text/javascript">
function changeImage() {
var oDDL = document.all("ddlNAME");
var NAME= oDDL.options[oDDL.selectedIndex].text;
switch(NAME) {
[Code] .....
When I call this function I do it in my DDL implementation.
<asp:DropDownList ID="ddlNAME" runat="server" OnTextChanged="changeImage()" >
But for some reason the changeImage() is not firing. It is giving me an error saying
'changeImage' is not a member of 'ASP.default_aspx'
I am making my site compatible to all browsers.For that on one page i am selecting the name from dropdownlist and on click of VIEW(button),i want to open a new window .i also want to send the value and text of ddl on new window. all of this i want to do on onClientClick or onClick of button...

input name="button1" type="button" id="btnview" style="cursor:hand" class="Buttons" title="View" value="View" onclick="alert(document.all('<%=ddlScheme.ClientID%>').value);"
[Code]....
I have a window having 2 dropdowmlists(schemename-SN and propertyno-PN) , one chkbox ,one "VIEW" button.SN has options "all" with value=0 and many other options with respctive values.Now,i want the code should behaves as follows:
1.0n window onload, SN must b visible bt PN nt.
2.if i select SN other thn All...the PN shud b visible and if i select "All" ,PN hides.
3.when check box is checked- PN hides,and if it is unchecked- PN visible..
Important:-This whole ddl n chk box are in updatable panel,button is nt in that.I want a browser compatible code so javascript can't b used directly(cz they give problem in mozzila and chrome).Right now, i have done this JavaScript and its is working fine.
function window.onload()
{
DisableProperty();
}
[code]....
but this code is not browser compatible.here onload,onkeyup and onclick functions are used , but they dont work in other browsers except internet explorer.
I have found a couple of examples on the internet to do this but really struggling to get it working in VB. (Tried a converter but had mixed results) I need the selection options of a Dropdownlist to be populated based upon the differing values in the first dropdown list.
Can anyone help with a releativley simple example in VB? Not fussed if the values are "hard coded" in the script. Or a SQL bit that pulls the data from a table
i am trying to do an assignment and trying to figure out the best way to implement it. My problem is i am telling sub-procedures to make this textbox visible and not visible depending on the selected change index. Is there anything wrong? In the form the visble property is set to false, but shouldnt it become visible when the index is changed?

View 3 RepliesI am not sure why I can't use pictureboxes when its visibility is set to false?? While the picturebox is not hidden, as part of my game I want the user to be able to guess where the picturebox is which means by clicking on it, it should trigger an event but even when I set this event, nothing happens. When visibility is set to true then the event triggers.
I want to be able to trigger events even if visibility is set to false,

I am having an issue with my code. I have button1 and button2 each attached to an mp3 file. When I click button1, track 1 plays. When I click it again, the track stops...same with button2. Problem I want to fix is that I want to be able to click button2 while button1 is playing, and have button1 return to the "stop" state while track 2 starts playing.

In my Vb.net project I have to use a toggle button. I could not find any such control in the Toolbox list.
View 2 RepliesFollowing some excersises I came across a visibility toggle for a menu item which does not seem to work:
Private Sub mnuMenuSize_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuSize.Click
If mnuSize.Text = "Short Menu" Then
[Code]...
If I click mnuSize on the menu it changes the text allright but leaves the visible property of mnuUnderline, another menu item, as it was. In the watch window before entering the click procedure mnuUnderline.Visible and "not mnuUnderline" are opposites allright(as they would have to be) but no swap occurs at the toggle line: mnuUnderline.Visible = Not mnuUnderline.Visible and the code doesn't report any errors either. mnuUnderline is indeed one of the available menu items. If I change the statement to mnuUnderline.Visible = mnuUnderline.Visible (bit of a weird statement allright) it will toggle exactly one time for no appearent reason.

View 1 RepliesCurrently my program randomly removes words from a set of text and inserts textboxes below the text. The user can then enter his/her answers in the new textboxes. What I would like to do is set the program so the user can have two choices one being Easy and other being Advanced. Then when the user hits either button it brings up everything that is currently on the form. I'd prefer to do this without having to use MDI forms. I've had a hard time using the MDI forms and therefore would like to avoid using them. They way I was thinking this could work is all objects would remain invisible except for the 2 buttons and then when you hit one of them they disappear and everything else appears.
View 1 RepliesI am using VB.Net 2003 (version 1.1) and I am attempting to open some forms with:
Dim myform As New FormX
If myform.Visible = False Then
myform.Show
End If
Problem is, no matter what, a New instance of the form opens. How do I check if an instance of myform is already open?
I've been working at this for hours, and I'm completely stumped. There may be a more elegant way to do what I want, but I can't find it in my reference books or online. I have a form that has 64 labels corresponding to 64 unique locations on a map. Each of the labels contains one character, a ●. The program determines, randomly, if these is something in those locations.'m using a For... next loop to step through each location and determine if there is something there.My question is how do I turn off the label in the form without resorting to some 64 choice Select Case statement (or something similar).
