I have a requirement where a user logs on to a server where exists a website. The user bring up the site on a browser on that server and loads a power point presentation slide. At that time, users using their laptop clicks on the link to that site and sees that particular PPT slide loaded on the server. Then the operator/user on the server clicks on the second slide and the laptop would now see the second slide. Is this possible to do? If yes, then what technology to use? DHTML? or something else.

I have a webform with a gridview displaying records which are selectable thru a "Select" button on the GridView control. Below the GridView, I have a DetailsView control showing details of the selected GridView record. Also, I have a "New" button which allows
me to add to the GridView and associated table thru SQL. In the DetailsView, I have a delete button which allows me to delete from the GridView and associated table thru SQL.
The issue I am having is that when I click the "New" button (to add a record), it performs correctly and displays the input-ready DetailsView with 2 fields for input. However, if I cancel that, and click "New" again, the DetailsView does not display at all.I am certain that I am binding the data correctly as I have several tests which implement the same logic with the only difference being that the tests require only one field while I now require 2 fields.

In a form, I have multiple images. Before saving the record, the image is been saved in a folder named "TransFiles". While saving, I move the image from TransFiles to location to be saved for the record.
For editing a record, when I change the image, it's been changed & saved to TransFiles. While saving also can successfully delete the existing image, save the new image with same name & finally delete the image from TransFiles folder. This all operations are performed perfectly well. In the server's images folder also, I find the newly added image under the name. But the Image control somehow shows the previous image only. On re-starting the app also. After 2-3 events of re-starting the app, it shows the new image.
What can be the reason for this ? The image is being stored in cache for that control or what ! How to show the proper image that's on the server on the Image control?

View 1 RepliesThis is my setup: I've got a dropdownlist of people and a linkbutton next to it to add a person. the linkbutton makes an update panel appear. When clicking save, I want the data to be saved and the new person be selected in the dropdown. As far as I can tell, I have done this properly. After I save the data I refresh the dropdownlist and take the new person's value and set it as the selected value. When stepping through, it shows the ddl with the new person and the new person selected! BUT, when the page comes back, the ddl is unchanged, ie NOT refreshed. I thought it might be something with the Update Panel but I got a similar setup to work on another page! It also works on a nested Update Panel (not shown in the following code). Can you think of why this "deception" is happening?
Here is some of my code.

View 2 RepliesI am having trouble with a dropdownlist and it's values not getting updated after postbacks.
Situation: I have an ASPX page that contains 2 user controls (UC1 and UC2). When the page first loads, controls on both UCs are set properly. My problem comes from the fact that when a dropdownlist on UC1 is changed, I need to reload a dropdownlist on UC2 (based on
the new value). I am raising an event from UC1 to the parent page when the dropdownlist value is changed and inside this method I am telling UC2 to reload it's dropdownlist based on the new value. When stepping through the sequence of events using the debugger, the values in the datatables and dropdownlists (item count) are 100% correct but after running through the logic, the dropdownlist on the page still has it's old values.
The initial values for the dropdownlist in UC2 are populated in Page_Load of the ASPX page, and nothing is done to the dropdownlist in Page_Load (!Page.Postback) of either the ASPX page or UC2. The only way I would like the values to change is when the event from UC1 is raised back to the page.
I have found a couple of other forum posts out there that had the same problem but I've tried those resolutions and nothing has worked. In the following examples, the value dt is the 'new' datatable that I wish to bind to the dropdown.I read that before rebinding the dropdownlist, that the Items need to be cleared and the SelectedValue should be set to NULL:
this.dropdownlist.DataSource = dt;
this.dropdownlist.Items.Clear();
this.dropdownlist.SelectedValue =[code]....

View 3 RepliesIn my Desktop i am binding Multiple UserControls. Each control has the Refresh facility. Is it possible to do refresh the particular UserControl with out page Refresh...
and one Important thing is I am binding User Controls dynamically..( in serverside while page loading)
I have a very strange problem here I am using a GridView which shows nothing the the page loads for the first time. But when user selects something from the dropdown above, it DataBind()s against whatever is returned by the stored procedure.
If ran the code in debug mode, it showed that gvMyGrid.Datasource had data in the list returned by SP.Then I did gvMyGrid.DataBind(), it keeps the same empty view.I tried one more thing, I bound the grid when the page loads for the first time to one of the default values returned. It showed the data but when I changed the dropdown selection, it kept the same data.
I have a form that when I click the delete button I want it to refresh the grid with that record removed from the grid. Does anyone know how to do this. Is this something handled in the code behind? Here is my code for the delete button on the design page:
[Code]....
I have a simple page, 2 textboxes & 1 button, wherein when button is clicked the values in both textboxes are added to a database table. code works however, when button is clicked the values are still in the textboxes. I created txt1.text = vbnullstring & txt2.text = vbnullstring after Myconnection.Close() just to delete the values in the textboxes.
but when I try to refresh my page, The values are still added to my table. I could redirect to a new page after a successful entry but, I just what to add a label saying "New Entry Added", clear the textboxes and waits for a new entry.
I have an aspx page that displays information from a database. This page includes a photo that comes from the database so I use another page ShowPhoto.aspx that just has Response.BinaryWrite(bytePhoto) and the image control Url is set to that page. The problem is when the record changes, the content is all changed but the ShowPhoto page does not refresh the image. The image is retrieved and set in the Page_Load of the ShowPhoto.aspx page and the Page_load event does not run after subsequent calls. Here is my code.
When the UserControl with the content is refreshed this code runs.
<pre>
private void GetBioContent(string lookup)
{
this.oContent = new PageContent();
this.oContent.GetContentByContentLookup("BIO", lookup);
bool hasImage = true;
[Code]....
The bio content also from the database refreshes so I know the user control is refreshing just fine. If you move to a bio that does not have a photo the ComingSoon.jpg from the file system is shown just fine. Then if you move back to a photo from the database it is correctly shown. The problem is moving from a photo in the database to another photo in the database and the new photo is not displayed. The previous one is still there. The code in the first section above does run but the page_load in ShowPhoto does not run.
How can I programatically just cause the showPhoto page to go away before calling it again so the Page_Load event would run and display the current photo?
