I have placed a label in user control. I am assigning a value from database during page load of user control and it works perfectly.
After database is udpated with new value, it is not reflected in the user control. I need to refresh the page to see the updated value. Can any one pls guide me how to update the label value in user control in aspx page.
I have around 8 user controls on a page with a form in each of them. I have a dropdown list that allows you to select a form, with a selectedindexchanged event that hides the current form and shows the requested form.
There is some javascript that needs to fire when each form loads. Now, when you click on a form for the first time, the javascript fires as it should, but if you click the dropdown to change the form, then click back to a previous form, the javascript doesn't fire (because the user control is already loaded).
Is there anything I can do to trigger a postback, or reload/refresh the user control whenever an option is selected from the drop down?
I need to trigger a postback or self refresh a user control from one of the functions in the same user control.
Problem is that I am setting the selected value of a dropdown control in this usercontrol but it does not actually show up until after a postback.
This I came to know after I found that the said drop down shows the current value only after I click on another button.
I need to do this on the server side in the function given below:
public void FillDropDown()
{
FillProgramList(select);
//if (Request.Cookies["prgname"] != null)
//{......

how to refresh user control on update.
I have a couple of user controls in an Ajax enabled page. Both controls are within TabPanels.
I'd like to be able to refresh certain items within userControl1, from userControl2.
I've added a public sub within userControl1 named "doRefresh" (that does what I need) but I can't work out how to reference it from userControl2.
Can anyone perhaps point me in the right direction with this?

I developed an admin dashboard to administer content for a tool i built, using vb.net, sql 2005, ajax, .net.3.5 I built a custom user control for each action, add page, update page, add image, update images, and added these to a multiview which loads all controls available to them on load of the page.
The problem is that on occasion the controls inside the multivew dont update, ie you add something, but it doesnt reflect the information in the db until the entire page is reloaded, usually via the user having to re open the page.
Is there a way to reload the user controls of the page programmatically (cant use a response.redirect or javascript due to values held within the page that must be maintained in order to keep user logged in)
I have a receipt page for my clients that will display their info and they will get notify by an email message. Here is the problem: when user hit refresh button from a brownser, it will send duplicate email message to the user.
This is what i have:
protected
void Page_Load(object sender,
EventArgs e)
{ if(!IsPostBack)
SendEmail()
}
protected void SendEmail()
{ //here is my function for email
}
I have a page which allows the user to send email. After they click the submit button, I display a confirmation message. However, if the user clicks the browser's Refresh button once the confirmation message is displayed, the email is sent a second time (or a third, fourth, fifth, etc.). What can I do to prevent the Refresh button from resending the email?
View 6 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?

View 1 RepliesI have an ajax asp.net page where a user has to make various choices, including radioboxes, checkboxes and so on.. It is made up of different views, and on the last one, i need to pull up a popup, but IE blocks them, and when you click to allow them, it automatically refrewshes the page and i lose everything that was chosen by the user.. Is there a way, perhaps using the PageStatePersister, to "save" the viestate into the session (i'm doing it) and load it back into the page after the refresh? Cause i think all the state is stored in the viewstate, but i dont know how to load it back into the page on the initial page load (after the refresh)

View 8 RepliesAll 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!
Parser Error Message:
There can be only one 'control' directive.

View 4 RepliesI am looking for a way to refresh one custom control inside a method of another. Here is what I have:
A.aspx <- contains (B,C) custom controls below
B.ascx <- adds data to SQL databaseC.ascx <- contains (D) custom control below
D.ascx <- shows data from SQL database
Data is added to SQL in the C# B.ascx code-behind method. Upon a new row being added I would like a GRIDVIEW inside the D.ascx control to refresh and show that new record immediately.
Initially I had all the code on the same page, but then needed to cut it into separate custom controls. The code worked perfectly fine before and now I need this refresh to happen again. The code I used before to refresh the gridview was like this:
// sqlSummary.DataBind();
// grdSummary.DataBind();
In the end I also need to update the screen. I used an UpdatePanel before, but no longer have it. Not sure what the best way to update the screen is with the new data.
I have a problem when I try to pass in paramaters for a report in my report viewer. I have set up the ObjectDataSource and set the paramaters for 3 text boxes that are on the page. The only way I have found to set the paramaters for the report is the user must fill in the paramaters and hit the refresh button on the Report Viewer toolbar ,but I would like to have the user click a asp.net button insted. Is there anyway to call the refresh method from codebehind?
View 1 RepliesI have an AJAX tab container with 2 panels within aspx page. Each panel hosts an ascx control. Each control contains GridView and FormView that are databound - 1st control to the parent table and 2nd - to the child. The 2nd control/tab contains standard DropDownList that is bound to the parent values so the user can select a parent to create "child" for. everything works fine except when the parent (on the 1st tab control) is created/updates the ObjectDataSource on the 2nd tab does not getting refreshed. Only after refreshing the hole page I can see the new "parent" value in the ddl on "child" page. I use strongly typed dataset. How I can programmatically refresh the DataSource? Simple rebinding didn't make a dent. Do I need to refresh page, the tab container, tab panel?
