I have a dropdown and multiple gridviews in the page .And on the basis of value selected from dropdown, data is loaded in Gridviews. And each gridview has linkbutton in each row, on click of which modal popup opens.
I want gridviews to be collapsed on dropdown select index change.
but my javascript function is not getting called.
And getElementByTagName('tr') is not working in internet explorer.
This is my Grid:
<asp:GridView ID="gvBillCalc" runat="server" AutoGenerateColumns="False" BorderColor="#CCCCCC"
BorderStyle="None" BorderWidth="1px" CellPadding="3" Font-Bold="True" GridLines="Vertical"
Font-Size="Small" EmptyDataText="No Data Found" Width="100%" OnRowDataBound="gvBillCalc_OnRowDataBound"
BackColor="WhiteSmoke">
<Columns>
<asp:TemplateField>
<HeaderStyle Width="25px" />
<ItemStyle Width="25px" BackColor="White" />
<HeaderTemplate>
<asp:Image ID="imgTab" onclick="javascript:Toggle();" runat="server" ImageUrl="../Images/plus.gif"
ToolTip="Expand" />
</HeaderTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Item Particular">
<ItemTemplate>
<asp:Label ID="lbDesc" Text='<%#Eval("desc")%>' runat="server"></asp:Label>
<asp:HiddenField ID="hdnID" runat="server" Value='<%#Eval("id") %>' />
</ItemTemplate>
<HeaderStyle Font-Size="14px" />
<ItemStyle Font-Size="12px" />
</asp:TemplateField>
<asp:TemplateField HeaderText="Amount(In Rs.)">
<ItemTemplate>
<asp:Label ID="lbAmt" Text='<%#Eval("total")%>' runat="server"></asp:Label></ItemTemplate>
<HeaderStyle Font-Size="14px" />
<ItemStyle Font-Size="12px" HorizontalAlign="Right" />
</asp:TemplateField>
<asp:TemplateField HeaderText="View/Edit">
<ItemTemplate>
<asp:LinkButton ID="lbViewEdit" runat="server"></asp:LinkButton>
<asp:HiddenField ID="hdnViewEdit" runat="server" Value='<%#Eval("flag") %>' />
</ItemTemplate>
<HeaderStyle Font-Size="14px" />
<ItemStyle Font-Size="12px" />
</asp:TemplateField>
<asp:TemplateField HeaderText="Remarks">
<ItemTemplate>
<asp:Label ID="lbRemark" Text='<%#Eval("Remarks")%>' runat="server"></asp:Label></ItemTemplate>
<HeaderStyle Font-Size="14px" />
<ItemStyle Font-Size="12px" />
</asp:TemplateField>
</Columns>
<FooterStyle BackColor="White" ForeColor="#000066" />
<RowStyle ForeColor="#000066" />
<SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
<HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
<EmptyDataRowStyle BackColor="#FFC0C0" Font-Bold="True" Font-Size="X-Small" />
</asp:GridView>
This is my javascript:
var Grid = null;
var UpperBound = 0;
var LowerBound = 1;
var Grid1 = null;
var UpperBound1 = 0;
var LowerBound1 = 1;
var CollapseImage = '../Images/minus.gif';
var ExpandImage = '../Images/plus.gif';
var CollapseImage1 = '../Images/minus.gif';
var ExpandImage1 = '../Images/plus.gif';
var IsExpanded = true;
var IsExpanded1 = true;
var Rows = null;
var Rows1 = null;
var n = 1;
var n1 = 1;
var TimeSpan = 25;
var TimeSpan1 = 25;
window.onload = function () {
Grid = document.getElementById('<%= gvBillCalc.ClientID %>');
UpperBound = parseInt('<%= this.gvBillCalc.Rows.Count %>');
Rows = Grid.getElementsByTagName('tr');
}
function Toggle() {
debugger;
var Image = this;
ToggleImage(Image);
ToggleRows();
}
function ToggleImage(Image) {
if (IsExpanded) {
Image.src = ExpandImage;
Image.title = 'Expand';
Grid.rules = 'none';
n = LowerBound;
IsExpanded = false;
}
else {
Image.src = CollapseImage;
Image.title = 'Collapse';
Grid.rules = 'cols';
n = UpperBound;
IsExpanded = true;
}
}
function ToggleRows() {
if (n < LowerBound || n > UpperBound) return;
Rows[n].style.display = Rows[n].style.display == '' ? 'none' : '';
if (IsExpanded) n--; else n++;
setTimeout("ToggleRows()", TimeSpan);
}
This is Code Behind:
protected void ddlNodeName_SelectedIndexChanged(object sender, EventArgs e)
{
if (ddlNodeName.SelectedItem.Value != "0")
{
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "CallMyFunction", "Toggle();", true);
Page.ClientScript.RegisterStartupScript(this.GetType(), "CallMyFunction", "Toggle()", true);
ClientScript.RegisterStartupScript(GetType(), "CallMyFunction", "Toggle();", true);
}
else
{
}
}

This[^] article has the sample on how you can use client side event. Also, it has sample on collapsing grid rows which might help you.

Can we do something with this forum software? When you switch between messages using the keyboard it would be nice to lock the message position. It would be pretty easy to add that functionality. Do you want me to do it?

Hi
I am working on an existing project inherited from one of these fly by night digital media companies. They probably had some amazing deadline as usual that results in bad website construction.
The developer at the time thought it great to use RequireJS and load every script file used by the solution into the main aspx page. So when you open/launch the website you are presented with a login screen. If you investigate the login page there is a list of script files loaded even if you never get to the subsequent page that use one of these script files. The second problem is that RequireJS also (sometimes) times out and some scripts are not loaded properly.
The problem I have is the following:
I need to strip out the scripts that is not needed at login stage and only include these scripts when needed. This means: still using RequireJS load the common script files in the main aspx and then when navigating to content pages include/append the additional script files without losing the common ones.
How do I accomplish this? Is there a way to sub load scripts?
What I have tried:
- Use require("script1", "script2", "script3"); in main
- Then use require("script4a", "script4b"); to add additional scripts. But this approach removes the common scripts ("script1", "script2", "script3") and only loads ("script4a", "script4b"), and I have 2 references to require.js as well.

Good Day all
i am reluctantly maintaining a Classic Asp application that will be re-written in few months to come. i have an issue where i have a Code like this
if(document.frmEntry.optMethod != "undefined")
{
if (document.frmEntry.optMethod.selectedIndex == 0) {
strPrompt=strPrompt+'Please specify the Valuation Method\n';
if ( objFocus == null ) {
objFocus = document.frmEntry.optMethod;
}
}
}
my problem here is that even if document.frmEntry.optMethod is not equal to "undefined" the code still go into the condition as if it was true. i have attached a proof in my debuger.

Try using a Falsy check.
The following values are always falsy:
false
0 (zero)
"" (empty string)
null
undefined
NaN (a special Number value meaning Not-a-Number!)
Your code should look like as follows:
if(!document.frmEntry.optMethod)
{
if (document.frmEntry.optMethod.selectedIndex == 0) {
strPrompt=strPrompt+'Please specify the Valuation Method\n';
if ( objFocus == null ) {
objFocus = document.frmEntry.optMethod;
}
}
}

You are very true about 'false' check, but sometimes it is a good practice to write full code and explicitly state against what are you want to check. It's of course only a matter of maintainability/readability...

That should be undefined and NOT "undefined"!!!

The "undefined" shown in the debugger is not a string, so you can't compare it as one.
To really test if your value is undefined, you can use this:
if(typeof document.frmEntry.optMethod != 'undefined')
The typeof operator returns the type of the argument as a string.

I can't see why use undefined as string - with or without typeof!?
In JavaScript undefined is a value property of the global namespace and yous should use it according to it...

The typeof for an undefined value is always "undefined". The value undefined being in the global namespace opens up some possible problems:
function madness() {
var a = 'fish', undefined = 'fish';
if(a === undefined) {
}
}
function mistake() {
var a = 'fish';
if(undefined = a) {
}
}
I know these are pretty unlikely scenarios, but better safe than sorry.
In earlier browsers "undefined" was not a testable value so expressions like (a == undefined) would produce the helpful message "undefined is undefined".

How that?
var undefined = 'fish';
alert(typeof undefined);

Yes. If you define undefined as a string variable, then it is no longer undefined and things get confusing.
This is why I was testing the type of the value against the string "undefined" - the string is a constant.

You can try with remove ("") double quotes OR use ('') single quotes.

I'm reading a tutorial about using selectors in jQuery to modify items on the page. I understand most of it, except I can't figure out why the first line of code below uses a comma to separate the selectors, and the second code line does not. Can anybody tell me when the comma is used and when not?
$('footer, header').slideUp('slow').slideDown('slow');
$('#Sidebar img').fadeTo(5000, 0.1);
The difficult we do right away...
...the impossible takes slightly longer.
