Why if I create a label on the load() event its properties are restored after a postback, even though it doesn't pass through the loadviestate stage?
Example:[Code]....
And why everybody advice to create controls in the overrides of the method LoadViewState(), if it's ok also in the load() event?
I have a gridview called gvResults. In the gvResults_RowEditing event I add a row below the one selected. In that new row, which spans all columns, I insert a user-control. There are two buttons and some textboxes in the user control.
My problem is that when I click one of the user-control buttons it never gets to the button event handler, I think because the user control is not recreated on the page postback. How can I have the user-control events fire before the parent page events fire?
I tried using an update panel, but I still get the parent posting back before the user-control events.
I understand I need to load my dynmaic control on every postback and preferrably in Page_Init(). But my dyanmic controls are loaded from a dropdownlist selectedindexchanged event handler. Now after any postback, my dynamic controls are gone. How would I force it to load on every postback ?

So when moving from the current app to the next I want to abandon the current session. However, this event is not firing before navigating to the next page. Could someone suggest a workaraound or the correct way to accomplish that?

View 1 RepliesI have a user control that will basically be a header in most of my pages, but not all.

Is there a way around this?
View 3 RepliesI have a question connected with controls and event handling. Lets say I want to create a LinkButton.
protected void loadLinkButton()
{
ContentPlaceHolder content = (ContentPlaceHolder)this.Master.FindControl("MainContent");
LinkButton lnk = new LinkButton();
lnk.ID = "lnikBtn";
lnk.Text = "LinkButton";
lnk.Click += new System.EventHandler(lnk_Click);
content.Controls.Add(lnk);
}
Here is the event handler:
protected void lnk_Click(object sender, EventArgs e)
{
Label1.Text = "ok!";
}
If I run the loadLinkButton function inside Page_Load everything is ok. But when I try to run the loadLinkButton by clicking simple button, link button is created but event is not handled.
protected void Button1_Click(object sender, EventArgs e)
{
loadLinkButton();
}
I there any way to solve it? Or loadLinkButton must always regenerated on Page_Load, Page_init etc.
I have a page called "EDIT.ASPX" on that page it has come TextBoxes, Label and 3 User Controls. When the Edit.aspx page is loaded all the correction form Controls are loaded properly, even the User Controls loads with no problem. The problem that I am expericing is that on the User Control I have a CHECKBOX with AutoPostBack="true". Each time the user click the CheckBox the User Control disappear. NOTE: How do I fix this problem and eliminate my page control from vanshing. The user control needs to keep the same state as the Edit.aspx page when the checkbox is clicked. I need to be able to click the checkbox without loosing any data on the page rather it's the Edit Page or the User Control.
View 5 RepliesI have a page with in a master page. This page has a user control with a text box and a button. I also have another button on the page. As the page first loads the button_click event on both the controls does not fire when clicking the buttons. I also have an event on the enter key on the text box. This event fires which causes a post back. After post back now my button_click event fire. The button_click event does not fire on the first page_load.

HELP ---> On the Uer control (SiteTemplate2.ascx) I have a DataList that is being populated by the database and that works fine. I have a
CHECKBOX on the user control page each time the user check the CHECKBOX the user control content totally disappears from the EDIT.ASPX page. There is no error message -- I believe this is a post back error but I don't know how to fix it.
Goal: Each time the checkbox called (CHKBSideBar) is clicked on the user control page all of the page content should stay in place that include
EDIT.ASPX Page and the refeneced USER CONTROL. I should be implement a CheckedChanged Function without either of the pages lossing DATA. I need to be able to access post back event from the user control of the Edit.aspx page. When the user click a box on the user control page how do I keep the same Page_Load event on the edit page. I need to reference the Edit page from the user control.
Note: The edit page loads the user control (SiteTemplate2.ascx)SEE CODES BELOW
I know this is a lot and thank you in advanced for your help. I tried to include all the pages that are key players. I must user the user control bacuase the user can select different template so eliminating the user control is not an option.

Here is my requirement -
1. I need to load a user control on link click event of a link button during postback of aspx page.
2. On button click event of a save button on that aspx page, I need to read the selected values from that user control on further postback.
If I write the loadcontrol code in link_click event, the control is not recognized at all in the button_click event. When I shift it to page_init and execute only during not postback, the user control loads with default values.
I have a table thats created dynamically, the table gets its contents from a custom class I've created that gets statistical data from a database. As the table is generated dynamically, I've put the contents class (the table data) into a session object and I populate the table initially inside a !IsPostback then on the page init I get the data from the session (its empty on the firts page load). I am now getting this error: Multiple controls with the same ID 'controlnamehere' were found. FindControl requires that controls have unique IDs. How can I avoid this?
View 4 RepliesI have a custom PagedDataSource created at page load.I have created two lin button "Next" and "Prev" to navigae the data source.I am using session to store the PDS and retrive it on each page load .I am incrementing CurrentPageIndex each time by 1 in the buttonNext click event and setting the value to the pds object.
What i am trying to do is, when the page loads, if page currently showing is last index, disable the "Next" button. The problem is, everytime I have to click "Next" one more time to make it disabled. It seems, the page does not recognize that it is the lastindex of the datasource when loading. When I click again one more time while in the last page , it is disabled.

I am using a third party gateway. The third party gateway does not support query-string , so i will need to post the form to pass the values to the given URL and another thing is that they don't expose the web-services so we need to use their page and that means we need to host it in an iframe in asp.net
so what i did is that i have hidden fields that will be used as parameters as depicted below
Code:
<input type="hidden" name="p1" value='4635' />
<input type="hidden" name="p2" value='Reference_test' />
<input type="hidden" name="p3" value='Purchase credits' />
[Code]..
Now the purpose of this , is to load the iframe after the page load event of the asp.net gets fired.
Now my problem here is that when the iframe loads , it does not pass the parameters to the url that is being set in the iframe.
I have attached the example, project. (2kb)
When you run the project you will notice when the iframe loads there is an Error
"NO VCS ID"
now this means that the parameters were not passed when the Iframe loads , i can understand because it seems like iframe does not do a full form post. so to demonstrate what i want, click the proceed button and you will notice it will give you a page with no errors and it will be a page where credit card details are required , i want to iframe to load that the first time.
