View 1 RepliesI should probably say I love these forums, I've been viewing for some time and have found loads of valuable information. I'm having a problem with my project, I have an updatepanel containing several items (Two Daypilot Schedulers and a Literal Control). I have set it to conditional and have it update whenever bookings are added/modified in the schedulers. This all works perfectly! I then have a literal control which contains div items with onmouseover= parameters. The control basically contains a list of pending booking requests. On Page_Load I call a method which populates the list...which works fine.
However, whenever I call the UpdatePanel.Update() method (say, when a booking is added), the schedulers update but the literal control does not. I have gone through the debugger and found that the LiteralControl.Text property is correctly set to the new updated list just before calling the Update() method. So basically it all works perfectly apart from the literal control not updating along with the schedulers in the UpdatePanel.
I have got a literal control on page (with some data on it). i want to access it in javascript and want to put some text on it. how can i access literal control in javascript. (i am using asp.net)
My code in javascript (but not working):
lths = document.getElementById("<%= lblhs.ClientID %>");

Why server control are not allowed inside literal server control

My issue is: i got a DevExpress control (ASPxGridView) that added and set-up in run time, since i activated the grouping functionality in the grid I still get JS error says ';' expected whenever i use (click) on one of grouping/sorting abilities, I activated script Debugging for IE, in the JS code turns out that there is no missing ';' and once i click ignore for the error msg that VS generates every thing works fine, and surly end-user can't see this msg so i figured out if i try/catch the script that may help avoid this error.
I wanna access the literal1 text which is placed inside panel 1 and panel1 is placed inside datalist1 ...
i wanna retrieve literal1 text on page load event using VB.NET
recently i used literals inside HTML elements like so:
Code:
<div <asp:Literal ID="ltlpbEmpty" runat="server"></asp:Literal> align="left" <asp:Literal ID="ltlToolTip" runat="server"></asp:Literal>>
<div <asp:Literal ID="ltlPBFull" runat="server"></asp:Literal> <asp:Literal ID="ltlBarWidth" runat="server"></asp:Literal> align="left">
</div>
in this case both of this divs are part user control progress bar i'm making, from not related reason i couldn't use ASP.NET elements and had to go back to the traditional HTML elements.so to be able to give those elements dynamic attributes such as tooltip, id, class i had to add literals inside those elemtns..
I have Repeater, which consists of LinkButon and Literal. LinkButon and Literal are whole thing by implication. I want get value from Literal, when user click on corresponding LinkButton.

document.getElementById('<%=DetailsView1.FindControl("TextBox1").ClientID%>');
I have written a web usercontrol (ascx). Inside, there is a Panel that I want to show/hide on click of a hyperlink inside the usercontrol.
Normally, this is easy just by doing something like this (the onclick attribute is added to the hyperlink on prerender):
var PanelToShow = document.getElementById('<%=PanelInvoiceHasBeenCreated.ClientID %>');
if (PanelToHide != null) {
PanelToHide.style.display = 'none';
}
but because the ascx control is held within the gridview, the above will assess all the controls (of which there are many in the gridview) with the name 'PanelInvoiceHasBeenCreated'. The only time it will work is when there is 1 row in the gridview. Currently, with my existing code, if I click the hyperlink in any row, it shows/hides the panel in the bottom row of the gridview!
Therefore, my question is how do I get the actual, unique ID I need to show/hide on the correct control in the correct row?

Can somebody show me a better approach of looping through a Try -Catch statement. I have something like this:
Try
dbConn.Open()
Catch ex As Exception
errmsg = ex.Message
End Try
I need to try to connect 5 times before logging an error. My first thought was to nest Try - Catch 5 levels but I didn't like that idea. I'm sure there is better solution to it.
I'm new to ASP.net 3.5 and creating a test web site. I have created a master page for my web site with page content blocks. Now I want to use some javascript on the client side to provide for more interaction. I would normally create page specific Javascript functions and insert them in a <script block on the page. Howevere the Javascript script block must be placed before the <HTLM block. If I'm using Master Pages, it doesn't seem that I can use page specific Javascript functions. How can I resolve this problem? I think my options are
1) Don't use Javascript. Use ? instead to write client-side code.
2) Don't use Master Pages because you cannot use Page Specific Javascript functions.
3) Here's how to insert Javascript Functions in a Page with a Master Page.
I was using the VisualTreeHelper trying to locate a textBlock inside the datagrid columnHeaders. I have just learnt that : "The Header object of the DataGridColumn is actually the visible header of that column, whatever you set it to be. DataGridColumn is not part of the Visual Tree so there is not direct way to access the DataGridColumnHeader for it (we can't even be sure it exists yet)... " This has set me back by a couple of days. I tried to convert the suggested code to vb.net in order to use it but I don't seem to get it right. The code in c# is :
Code:
ataGridColumnHeader headerObj = GetColumnHeaderFromColumn(column);
private DataGridColumnHeader GetColumnHeaderFromColumn(DataGridColumn column)
{
// dataGrid is the name of your DataGrid. In this case Name="dataGrid"
List<DataGridColumnHeader> columnHeaders = GetVisualChildCollection<DataGridColumnHeader>(dataGrid);
[Code] ...
How to apply it in my scenario shown below. I want to access in order to rename the textblock 'columnHeaderName'. How can I do this?
Code:
<Datagrid>
<Datagrid.Columns>
<DatagridTemplateColumn Header="header1" Width="100">
<DatagridTemplateColumn.HeaderTemplate>

Since everyone yells at me that MessageBox doesn't work when the project is uploaded to the server, I need to migrate to javascript alert box. As I was changing my MessageBoxes, I tested and found that they weren't being produced. I'm not sure if it matters, but they are in a try/catch block, which is shown here:[Code]....
This all worked before when I had MessageBox - it showed, then the page redirected when I clicked Ok.
I either don't understand how try/catch works, the javascript isn't adding, or Response.Redirect is executed before I can see the alert box and click Ok on it.
(just as a note, everything works fine, but the alert box doesn't show)........if I add the (javascript) code before the try block, the alert box comes up, so it's not something wrong with the writing of the javascript or executing it at least (I think).
I'm working on a web where i have a Tabcontainer in which I only use two tabs, and what i do there is that I added a control to show virtual keyboard (VK) for use with tablet PC or mouse, it will appear when a textbox is onFocus.
The problem is that when I add the control VK inside a Tabpanel, run the page, and when I focus the textbox inside the Tabpanel, it doesn't appear the VK, but i try using outside the tabpanel and it work. I also added an updatepanel inside the Tabpanel, and moved the textbox and VK control there, but is the same, it doesn't appear the VK.
i will show my web code and a link to the VK control web, cause I think it have to be a way to call the keyboard in client-side mode, but i tryed all i know and nope, isn't showing the VK.
[Code]....
The web VK control: [URL]

i have grid that uses around 12 to 15 label when i bind it...and grid contains thousands of records, now if i'll use literal control instead of label will it to improve the speed.
View 4 RepliesThis is a problem I'm facing in a webapp I'm currently working on. So instead of cluttering the question with unrelated code, I recreated the problem in an isolated, simplified webapp that only demonstrates this issue.
I have a web user control with just this as its content:
<% if (ShowAlertScript)
{ %>
<script type="text/javascript">
function AlertMe()
{
alert('Hello World!');
}
</script>
<% } %>
<input type="button" onclick="AlertMe()" value="Say Hello" />
And its codebehind has nothing more than the boolean definition of ShowAlertScript. This represents a control I have in the big webapp that has two modes: input mode, and display mode. When in input mode, it has a large javascript block that is only useful then; it does some cool stuff to help the user input the info.The way this control is laid out in the big picture is as follows:
<asp:ScriptManager runat="server" />
<asp:UpdatePanel runat="server">
<ContentTemplate>
<asp:MultiView ActiveViewIndex="0" runat="server" ID="mvw">
<asp:View runat="server">
<asp:Button runat="server" ID="btnSwitch"
OnClick="btnSwitch_Click" Text="Switch" />
</asp:View>
<asp:View runat="server">
<uc:MyInputControl runat="server" ID="micInput" ShowAlertScript="true" />
</asp:View>
</asp:MultiView>
</ContentTemplate>
</asp:UpdatePanel>
When you click btnSwitch, it simply switches to the second view with the user control. Notice how I have the ShowAlertScript already initialized to true. The potential output is that since I'm "showing the alert script" within the user control, the AlertMe() function will execute when you click the input-button element, because it's written out according to the inline if statement.
If you run this code I gave you so far as is, it will not work. The browser will say it can't see the AlertMe() function; it's undefined as far as it knows. But if you take out the UpdatePanel (or disable the ScriptManager's partial rendering), it will work just fine on a full postback when you click btnSwitch.
I want it to work on a partial postback, because this whole thing is a small piece compared to the rest of the page, and I don't want to do a full postback every time they switch views. Apparently, the ScriptManager doesn't even bother re-rendering the ascx file for possible changes. Either the ScriptManager is not smart enough, or there is an option I'm missing to let it render the <script> so I can invoke its methods on the client side. A potential answer someone might suggest is "why don't you take out the javascript, put it in its own .js file, and have the page reference it so it's available to the control?"
That won't really work with me, because the script block does some initialization and modification that pertain to that single control instance, not to all others on the page.
In turn, you might also be concerned that if I have more than one instance of the control, I end up with copies of the same script. Not really; there will only be ONE input mode of this control in a page at any given time, it's just that I have those two modes in two separate views and I let the user switch between them.
how can you reset asp control inside a form using javascript?
Code:
<script language="javascript">
resetform(){
form1.reset();
}
Code:
<form id="form1>
...more codes here for asp controls
<input id="Button4" type="button" value="button" onclick="javascript:resetfom();" />
</form>
I have js script block (very long one that does editing capabilities to an invoice page).
I want to enable/disable this functionality on the server-side. First thing popped up on my mind was to say runat="server" to the tag, and set visible=true/false to asp.net, thinking asp.net does not render the HTML for non-visible items, so the block wouldn't load at all, which was what I wanted. But I quickly realized that saying runat="server" to client-side code was a real bad idea :)
What ar emy options, besides loading script from client side. Cuz I have other buttons that come from the server-that will enable dieable too.
I am trying to call a JavaScript function from my ascx control code behind in the catch blockI have tried the below two ways but they don't seem to work.
Page.ClientScript.RegisterClientScriptBlock(typeof(string), "script", "test();", true);
ScriptManager.RegisterStartupScript(Page, GetType(), "err_msg", "alert('error');", true);
