iframe and setfocus problem

Posted By:      Posted Date: August 25, 2010    Points: 0   Category :ASP.Net

I have a page with an iframe on it in which I load another page.
On this iframe page I have some textboxes above eachother.

When the first textbox is filled with a code the textchanged event is called 
and the code is checked with the database.
After the code has been changed to the right one (if needed) I want the 
focus to go to the next textbox.

So at the end of the event I do: Page.SetFocus(txtbox2)

But after the postback refresh, the focus is gone.
I have also put the control to be focussed in a session variable and then in the page_load event I set the focus to the control in the session variable, but still no focus on the textbox.
How can I put it on the 2nd textbox? 
all is done in the Iframe page codebehind.
I need this focus because the two textboxes are filled via bar code reader and after the scan an "enter press" is done automatically and to be able to allow two scans after each other this focus change is needed.

ModalPopupExtender and IFrame problem


Here is my problem, please give your suggestion:

I have product list on parent page in grid view. When user click on insert new product button, the modal popup will display. Modal popup has <asp:panel>. In asp:panel, I have IFrame for AddProduct.aspx page.

1) I can add, modify or delete the product on modal popup(AddProduct.aspx) but when I close the popup window, I want the product list on parent page should be refresh. So we can see updated data.

2) Right now, I am using static IFrame src="AddProduct.aspx" but I want to pass the selected product ID from parent Grid view using query string like src="AddProduct.aspx?ProductID=20".

Please guide me how to do this?? Thank you.

Iframe / window.parent problem



I'm trying to make an ajax-enabled uploader so I'm using an Iframe to upload the image and the Iframe is embedded in an Update Panel which helps me prrevent a full page postback.

The problem is that from the Iframe, I have to call a script that clicks a button from the parent page  using the a ScriptManager's RegisterStartupScript attribute. The script "iFrame_OnUploadComplete()" clicks a button that uploads the file. I call the script from the Iframe like so:

 protected void btnUpload_Click(Object sender, System.EventArgs e)

ClientScript.RegisterStartupScript(Page.GetType(), "Upload Completed", "window.parent.iFrame_OnUploadComplete();", true);


The above method calls the parent page which helps save the uploaded file.

The above method works on my local host where I call Iframe URL from the parent page like so:

        <iframe src="http://localhost:4145/CustomControls/UploaderAssistant.aspx" >

This works perfectly on the local host.

But when we move to IIS, and we use an absolute domain name like so

        <iframe src="sub.domain.com/CustomControl

Thats why i tried to group the radio buttons in vertical manner. Let i have a requirement like below:

ASP.Net Caching problem ??


I'm having a problem with an asp.net 3.0 application using a gridview to display data.  The problem seems to be that despite a brand new .selectCommand being sent to the sqlDataSource, the gridview starts displaying data from *someone else's* query.  For example, user A is logged in and will be working fine until a few page submissions later when the gridview data starts suddenly showing information that belongs to another user. 

This is my first asp.net application, though I've been working with classic asp and ADO for years so I'm used to sending a SQL string and getting back the results from that string.  Apparently there is a complex caching system which is interferring which I do not at all understand so at this point I just want to stop the server from caching any data whatsoever.  Is this possible?

Any and all help will be much appreciated!!

RaiseEvent problem


I have a parent page ProdView.aspx and two static UserControls, UC1 and UC2. Each UC is in an Ajax accordion pane and the accordion inside an updatepanel.

UC1 has a Gridview footer with couple of textboxes and a link button that fires an Add Row insert procedure. I want to Raise an event that will rebind the UC2 after the row insert in UC1.

First I created the sub delegate and event in UC1:

  • Public Delegate Sub MyRefresh(ByVal sender As Object, ByVal e As CommandEventArgs)
  • Public Event Refresh_UC1 As MyRefresh

In the same UC1 the Insert procedure that fires the insert and RaiseEvent:

Sub PricingGrid_Insert(ByVal sender As System.Object, ByVal e As EventArgs)
       Dim myConn As SqlConnection = New SqlConnection(ConfigurationManager.ConnectionStrings("LocalSqlServer").ConnectionString)
       Dim myCom As SqlCommand = New SqlCommand("AddRow", myConn)
       myCom.CommandText = "AddRow"
       myCom.CommandType = CommandType.StoredProcedure
