Change button text on ASPxPopupControl buttons

I am trying to change the text of ASPxPopupControl buttons (I have not written the ASPxPopupControl code myself. Those guys are long gone. :) So it's up to me). As far as I know, the ASPxPopupControl default buttons are used and if I want to change the button text I have to add code to the .aspx file. I have tried searching for an answer on the DevExpress docs and the world wide web. But could not find anything that matches my needs. I am very grateful for any ideas.
This is the buttons I am talking about:
The ASPxPopupControl code (There is an attempt to add a custom button but it does not work.):
<dxpc:ASPxPopupControl ID="someLongID" runat="server"
AllowDragging="True" ClientInstanceName="someLongID"
CloseAction="CloseButton" HeaderText="Varning!" Modal="True"
PopupHorizontalAlign="WindowCenter"
Width="300px">
<ContentCollection>
<dxpc:PopupControlContentControl ID="PopupControlContentControl3"
runat="server" Enabled="True">
<p>
<br />
</p>
<p align="right">
<input
id="Button1"
onclick="javascript:someLongID.Hide();"
type="button" value="Stäng" />
</p>
</dxpc:PopupControlContentControl>
</ContentCollection>
<HeaderStyle BackColor="#FFB6C1" />
</dxpc:ASPxPopupControl>

If you don't implement you own popup edit form, but use the built-in one, it is necessary to access the required text setting via the ASPxGridView.SettingsText (CommandUpdate, etc.).

I think you can change the text content in the item property (in "Properties") which is located in the right down corner on VS.
you can click on the item in "Design" mode and then check its setting in "Properties"
Hope this helps

Modal Popup not firing in C#

I have been trying to get a Modal Popup to work for the last few months. I try and try, and after a while I just give up and find another way to work around it. I am very new to programming and have been doing some helpful things for my department, but in order to make these things viable alternatives I need to get more functionality out of them.
I want to be able to update a row in my SQL server, but the gridview is pulling data from a View, so the built in edit options won't work for me. I was hoping to be able to have a Modal Popup appear on the screen so that I can have the user put the data in and it will build the proper SQL statement to update the row.
I can't even get a Modal Popup with a single line of text to 'popup' though.
At the top of the page I have this:
<%# Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>
Then in my main div I have this:
<cc1:ToolkitScriptManager ID="ToolkitScriptManager1" runat=server"></cc1:ToolkitScriptManager>
Then down in the body I have this:
<asp:Button ID="btnTest" runat="server" Text="Test" />
<cc1:ModalPopExtender ID="mp1" runat="server" PopupcontrolID='pnlEdit" TargetControlID=btnTest" OkControlID="btnSubmit" CancelControlID="btnClose" BackroundCssClass="modalBackground" ></cc1:ModalPopupExtender>
<asp:Panel ID="pnlEdit" runat="server" style="display:none">
<div class="modalPopup>
<p>Text goes here.</p>
<asp:Button ID="btnSubmit" runat="sever" Text="Submit" />
<asp:Button ID="btnClose" runat="sever" Text="Close" />
</div>
</asp:Panel>
Code Behind currently has nothing for this. I have tried the same code with the variation of giving the btnTest an OnClick that does mp1.Show();. And also tried adding a "dummy" TargetControlID that is rendered but not shown in order to use the Code Behind to fire.
Every variation produces the same results. The "Test" button is clicked and then nothing happens. It appears that the page is reloaded. What am I missing here?

Please take a look at this Solution

How to make a button not show up but still be used by javascript?

I am using a button that has to be invible and should be used by a javascript function.
<asp:Button ID ="btnDummy1" runat="server" Visible ="true" OnClick="btnSubmit1_Click" width="0px" height="0px"/
I cannot keep visible = false as it the javascript will not use invible content in the poage. I havetried to give width=0 and height=0, still it showws up in Chrome. What do you guys think i should do?
Thanks in advance :)

A pretty clean approach in ASP.Net it give it a "hidden" class:
<asp:Button ID ="btnDummy1" runat="server" CssClass="hidden" />
Then in your stylesheet:
.hidden { display: none; }

If you set it to Visible="False" then the code will not be executed.
Instead I think you should wrap it in a <div> and set display:none via css:
<div style="display: none;">
<asp:Button ID ="btnDummy1" runat="server" OnClick="btnSubmit1_Click" />
</div>

adding style="display:none" would hide the button till you make it visible again
<asp:Button ID ="btnDummy1" runat="server" OnClick="btnSubmit1_Click" style="display:none"/>

How about
style="display:none"
for the button instead of Visible = "true".

Can you just use a hidden form field in this case? This is generally the preferred method of passing information along.
See http://www.tizag.com/htmlT/htmlhidden.php

<asp:Button ID="btnMyOrders" runat="server" Text="my orders" CssClass="dropdown-item" OnClick="btnMyOrders_Click" Visible="False" />
Example then in Form(){
btn.Visible = true; to show it again
}

I think the first question you should ask yourself is : why would I put in my HTML doc a button that should not be visible ?
An HTML document should be used ONLY TO DESCRIBE A CONTENT'S SEMANTICS. So an HTML doc should ONLY contain the content you want to publish and extra data to explain the content's SEMANTIC !! NOTHING about the way it is displayed, NOTHING about the way it behaves !!
All displaying and behaviors questions should be managed with CSS and Javascript, NEVER within HTML itself.
Any element needed for Javascript only purpose should be added in the doc by Javascript itself !
You should never find, in an HTML doc, such things as prev/next buttons for a javascript picture gallery for example. The HTML doc should only contain the pictures list, than your JS script will change the way this list is shown, making it a eye candy gallery and add buttons for navigation.
So in your example, your saying you want to add in your HTML doc an invisible button with some Javascript actions on it.... that's probably an example of some content that should never be in the HTML doc.

Show and hide labels with assosicatedControls and their controls

I want to show and hide a label and its control. I can do this in c# in the code behind. But, I can only show/hide the control. Any ideas?
<asp:label AssociatedControlID="thisLabel" runat="server">This:
<asp:label ID="thisLabel" CssClass="ascontrol" runat="server" />
</asp:label>
I want to be able to show and hide that whole thing depending on what user gets to the page. I just need to know how to show/ hide that whole thing in the c# code behind...cannot seem to get the visibility of the wrapper label to go away.

You haven't supplied a server-side Id:
<asp:Label ID="label_MyControl" AssociatedControlID="txt_MyControl" runat="server" />
<asp:TextBox ID="txt_MyControl" runat="server" />
What you've done is nest a asp:Label control within another asp:Label control....

Since I normally hide more than one field contiguously, I tend to wrap the whole thing in an asp:Panel and hide the panel. However, that's just my particular usage. But since it's my usage, I tend to block those sorts of things out into panels even for something as simple as your example.
Just my nickel's worth, your mileage may vary, as always.

It should work if you get you r markup correct, like this:
<asp:Label ID="lblYear" runat="server" Text="Year (yyyy):"
AssociatedControlID="txtYear"></asp:Label>
<asp:TextBox ID="txtYear" runat="server" Columns="30" MaxLength="4"></asp:TextBox>
Then in the code behind you could have:
lblYear.visible = False
txtYear.Visible = False
Now, my understanding of the "AssociatedControlID" property of an asp:label is mainly for accessibility purposes. You don't need to have the AssociatedControlID value set to make things work as I've shown.

Attach event to control inside a Placeholder using designer ASP.NET C#

Is it possible to add an event to a control which is inside another control, like say a PlaceHolder control using the designer?
When the control is alone on the form this works perfectly... you simply add it from the properties window by clicking the thunder icon and clicking on the event needed.
I know I can do by adding it manually but it would just be faster if it were generated for me.
To test this, add the following to a form and try adding the OnClick event of the btnTest through the designer or properties window:
<asp:PlaceHolder ID="phTest" runat="server">
<asp:Button runat="server" Text="Button" ID="btnTest" />
</asp:PlaceHolder>
Any help is appreciated
Regards

<asp:PlaceHolder ID="phTest" runat="server">
<asp:Button runat="server" Text="Button" ID="btnTest" OnClick="bUpdate_Click" />
</asp:PlaceHolder>
I have had to do it manually in my project and as long as you match up the eventargs it was straight forward

I don't think PlaceHolder control is using for this purpose. From MSDN
The PlaceHolder Web server control
enables you to place an empty
container control within the page and
then dynamically add, remove, or loop
through child elements at run time.
The control only renders its child
elements; it has no HTML-based output
of its own.

Well I guess there is NO way it can be done through the designer, except by adding the eventhandler to the button before you put it into the Placeholder.
Thanks for the help guys...
