I have a hidden variable and its value is being updated using javascript(client side) which I make a call from server side code. After making the call I am not able to retrieve the updated value from Server side variable. I went through this forum [URL] but not able find a way how to implement functionality with IFRAME. I am trying to call the client side code and retrieve the updated value from server side in page_load event.

View 4 RepliesI've got two textboxes running server side and have their visibility turned off. I'm using a couple of ASP.NET controls which require the textboxes to exist. However, I am filling them from the code behind and would not like the user to see this. Can the user turn the visibility on and see the values entered in the text box? I tried using FireBug, and I couldn't seem to select the visibility option in order to edit it. However, I'm quite new to Firebug, so there may be another way? Or does running it server side mean that the client can't ever view the contents of the textbox?

View 2 RepliesFor the ASP.NET validator controls, I want to use both client-side validation for the user experience and server-side validation to guard against hackers. ASP.NET documentation leads me to believe that if EnableClientScript="True" then there will be no server-side validation if client-side validation is possible for the user agent. To get server-side validation, the documentation says use EnableClientScript="False", which bypasses client-side validation altogether.
Am I misunderstanding how the validator controls work? I ask because it seems obvious that many developers would want both client and server side validation together, and I find it hard to believe both together is not possible with one of the standard validation controls.
If I am understanding the ASP.NET documentation correctly, then I can find only two options:
Use two validator controls exactly the same except for their ID and EnableClientScript properties. Obviously ugly for maintaining two controls almost the same.Write some code behind to check if postback then invoke the Validate method on the validator group. Why write code behind if there a way to be automatic from the control?
Is there a way to do so using a single validator control with no code behind?
I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");
[code]...
Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.
how to get HTML control value server side . I have the following control.

I am trying to render the Button control @ serverside with PostBackUrl properties to set to another page ""~/page1.aspx". When I click on that button , it still postback to same page , does not postback to "page1.aspx" . I am trying to implement crosspage postback. I don't know button information and postbackurl info at design time. I Only know button and PostbackUrl info @ runtime.Code I am using
protected void Page_Load(object sender, EventArgs e)
{ div1.InnerHtml = GetRenderControl(); }
public
string GetRenderControl()
{ Button buttonAdd = new Button();

I have created some dynamic controls, at the runtime from server-side and I want to write the event-handler for those controls. All I did is :
// Defined the control as
[Code]....
// And I wrote the even handler as :
Private Sub addobjective(ByVal sender As Object, ByVal e As System.EventArgs)
End Sub
My problem is the event-handler function addobjective() is never being called and not getting fired, So the program is not doing what it is supposed to do at the click event of the server side commandbutton add.

I have to access my html control and get its value from my server-side code. Is there anybody who could suggest how I could do it?
My html control is very simple: <input type=text>
But the thing is: I can't make it <input type=text runat=server> cause in this case my jquery functionality (datepicker) does not work.
I'm using Treeview control with asp.net 2.0. I would like to know how to get the client side events working. I don't want a post back for every little thing i do with the Treeview. Particularly i want to catch the node click event on the client side using java script, i want to enable/disable buttons based on the selected node. Is this possible? i tried some examples available on net but doesn't seem to be working.
View 6 RepliesI'm new to writing custom ASP.NET server controls, and I'm encountering the following issue:
I have a control that inherits from System.Web.UI.HtmlControls.HtmlGenericControl. I override the control's Render method, use the HtmlTextWriter to emit some custom HTML (basically a TD tag with some custom attributes), and then call the case class' Render method.
Using the control:
<dc:Header id="header1" runat="Server" DataColumn="MemberNumber" Width="30%">Member Number</dc:Header >
The problem is that when I view my rendered HTML, the server tag is emitted to the client as well (right after the TD tag):
<dc:Header id="ctl00_ContentPlaceHolder_testData1_testData1_header1">Member Number</dc:Header>
How do I prevent this from happening?
I have just run into a situation with a FormView control where any markup that is not given an ID and runat=server attribute is NOT rendered to the browser.
In other words, all of the extranneous markup (h#, fieldsets, legends, divs, labels, etc.) that are in my Edit Template DO NOT render to the browser at run-time. However, if I add an ID to any of those items and add runat="server" then they are rendered.
Has anybody every seen anything like this? Does anybody know what could possibly cause this?
I want to rotate the text vertically in all general browser. I find some solution, but it works on some broswer and not on some browser. how to rotate the text vertically in almost all the genral broswers.
