I'm adding a User Control to my aspx page at Run-Time like bellow:
UserControl uc = new UserControl();
uc = LoadControl("UC1.ascx") as UserControl;
PlaceHolder1.Controls.Clear();
PlaceHolder1.Controls.Add(uc);
---------------------------------------------
There is a Button in the User Control its Click event not working. What's the problem?
i create a composite control as can be seen in code below, and add this control to webform, assign FormView1 to the HeaderControlName property, Run the page, the system will generate parse error message :
Cannot create an object of type 'System.Web.UI.WebControls.FormView' from its string representation 'FormView1' for the 'HeaderControlName' property. However, if i don't assign FormView1 in design screen and manually (through coding) assign FormView1 to the custom control on init, it works as expected.
custom control
public class CmdTest : CompositeControl
{
public virtual FormView HeaderControlName
{
get
{
object oObject = ViewState["HeaderControlName"];
return (oObject == null) ? null : (FormView)oObject;
}
set
{
ViewState["HeaderControlName"] = value;
}
}
protected override void CreateChildControls(
{
Controls.Clear();
Button xx = new Button();
Controls.Add(xx);
}
}
webpage.aspx (assign FormView1 in design time, it will generate error)
<Utils:CmdTest ID="CmdTest1" runat="server" HeaderControlName="FormView1" />
webpage.aspx (didn't assign FormView1 in ASPX, but assign it on Init Code, it works)
<Utils:CmdTest ID="CmdTest1" runat="server" oninit="CmdTest1_Init" />
Webpage.aspx.cs
protected void BsCmdTest1_Init(object sender, EventArgs e)
{
CmdTest1.HeaderControlName = FormView1;
}

I have the user control and web page. When I place user control in the web page and in design time, it cannot view and error is "System.Web.UI.UserControl does not have a public property named 'ContentTemplate". It seems not related of error message.
View 5 RepliesI am fairly new to the asp.net and experimenting with it to learn the page life cycle. Here is a problem that I have been unable to resolve for past few days.I have a hosting page (.aspx). Then I have two user controls (.ascx). The page has a place holder control in which it loads the user controls one at a time based on the application flow. First user control is loaded on application start up. It has a "continue" button. Continue button click loads the Second user control that has two buttons - "Back" and "Submit". Obviously the "Back" button should load the first user control again and Submit button should submit the form data.
View 3 Repliesi created a user control and place a button on it.i drag dropped the user control on a aspx page and wrote the grid load and button clicks in the
user control.now i got a requirement to use the same user control grid and button to again use on the same page.however the data populated will be different and the button click functionality will be different.how can i reload the different data on the second grid as i had already wrote the code in the first one
I have a page that has a bunch of user controls. I would like to be able to see which user controls are performing badly. I would like to be able to see this in the trace. any way to do this.
View 2 RepliesI render some markup dynamically in a Web User Control, can I get that out in design mode, and not only runtime?
public override void RenderControl(HtmlTextWriter writer)
{
if (this.DesignMode)
writer.Write("<p>In design mode</p>");
else
base.RenderControl(writer);
}
... nothing happens when I check the design view of the control. Not if I remove the if (this.DesignMode)-condition either.

I have a hosting page (.aspx). Then I have two user controls (.ascx). The page has a place holder control in which it loads the user controls one at a time based on the application flow. First user control is loaded on application start up. It has a "continue" button. Continue button click loads the Second user control that has two buttons - "Back" and "Submit". Obviously the "Back" button should load the first user control again and Submit button should submit the form data. Pretty simple.
The problem is that the command button event handler that I have on the second user control is not firing the first time. (I have one event handler for both buttons). The load event of the user control fires but then it ignores the button click. If I click it again, then it fires. I re-load the controls on the page in every page_load. Here is some relevent code:
AddPlayer.aspx:
[Code]....
The page_Load fires every time but "CommandBtn_Click" doesn't fire after the first click. I have to do it click it again. It doesn't matter which order I click the buttons.
I'm getting some wierd behaviour with my User control. I've created User control & it has BUTTON which checks the validity of the number entered in the textbox of that user control. I have written Button Clik event handler in the USer Control code behind which checks the database table and tells valid or not. So far so good. In my application i dynamically add User controls. I make sure that I add them Page_Load so that for every postback UCs are visible. I'm ussing Session to save my UserControls. The problem starts at some point when i click the Validate button in the User Control all my user controls dissappear & after some postbacks all my controls appear. I don't know why this is happening. I have included my code for reference.

View 1 RepliesI don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?

All I would like to be able to do is include one user control within another! Is this possible? I have spent the last hour searching the internet and it seems that I can't find a single thing.
In classic ASP it would be something like:

I tried this but no luck!

There can be only one 'control' directive.

View 1 RepliesI have written a SP which maintains users log in and log out history,it works fine when any user logs in or clicks on log out, problem is that as per need its not to allowed to keep the screen idle for 1 minute or more then in the log out column Null value is passed.
SP
Create proc usp_trackuserlogindetails
@username varchar(50) = null,
@command int = 0
as
BEGIN
if(@command = 0)
begin
insert into userlog (USERNAME,LOGIN,LOGOUT) values (@username,Getdate(),Null)
[Code] ....
Here when user manually clicks the log out button then 1(table above) is the output.
When user leaves the screen idle then after 1 minute the page goes to the Login.aspx page if the user tries to do something on the current page,here 2(table above) is the output can i store some hard core value instead of Null like Session expire or the exact session expires time.
How get current date and time
example: TimeZone(UTC +10)
<html>
<head>
<script type="text/javascript">
function ClientTime() {
var dt = new Date();
var ss = dt.getSeconds();
var mm = dt.getMinutes();
var hh = dt.getHours();
