Web Forms :: DetailsView Refreshing ?
Apr 12, 2010
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.

I have a scenario in which the user can add a new option to appear in the list of available choices in a DDL contained in a detailsview when they select an option <Add New>. This displays an AJAX model popup which then allows the user to enter the new option text. Then they hit an Insert button which inserts that new option into the DDL's datasource and I call ddl.DataBind. Subsequently I want to close the modal popup and then display the newly created DDL option as selected.
When I step through the code, everything appears to be working as expected...i.e. the DDL's datasource now has 1 more record than before and the ddl.SelectedValue is the newly created record for its datasource. I can also query ddl.items(99) and see the new option is part of the ddl's items collection and the new record is Selected.
HOWEVER, once the screen comes back from the debugger, the DDL is now showing the newly created option, but still the prior selected option of "<Add New>". And if you pull the DDL down the newly created option is not in the list?
I cannot figure out how that happens...though I suspect it has something to do with the AJAX/Update panel. Here's some code:

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´m trying to link the gridview to detailsview and I used this page as my inspiration:
http://quickstarts.asp.net/QuickStartv20/aspnet/doc/ctrlref/data/detailsview.aspx
But I´m trying to do that programmatically, not with the sqldatasource. So I wrote the method that binds data to Detailsview and I call it in the page_load. The problem is that I have to click two times on the select button to view the detailsview. The first time I click on the select button nothing happens.

I know the back button always presents a problem, but this one doesn't make any sense.
I have a simple details view and a button on a page. The button sends the user to the homepage. I am trying to prevent the user from being able to use the detailsview if they click Back in their browser.
This is the button click event
[code]....
When the button is clicked...oddly the user is sent to the homepage then when they click the browser back button they are sent to previous page with the detailsview still visiible.
I know I am missing something, can someone fill me in?
Why is the detailsview still visible?

I am searching for a customer and displaying results on the same form. Now for some reason even If I am searching using correct format of the data the system is showing some predefined error messages. This measn that my previous error message is not refreshing.
This is the code:
if (txtANumber.Text.Length == 0 && txtBNumber.Text.Length == 0 && txtCNumber.Text.Length == 0 && txtDNumber.Text.Length == 0 && txtLastName.Text.Length == 0 && txtFirstName.Text.Length == 0 && txtDOB.Text.Length == 0)
{
GridViewCustomers.DataSource = null;
GridViewCustomers.DataBind();
lblNoResultsMsg.Text = "Please enter search details";
lblNoResultsMsg.Visible = true;
valid=false;
}
else
{
if (errors== 0)
{
GridViewCustomers.DataSource = null;
GridViewCustomers.DataBind();
lblNoResultsMsg.Text = "Please enter correct format of A Number ";
lblNoResultsMsg.Visible = true;
valid = false;
}
else if (errors== 2)
{
GridViewCustomers.DataSource = null;
GridViewCustomers.DataBind();
lblNoResultsMsg.Text = "Please enter correct format of B Number ";
lblNoResultsMsg.Visible = true;
valid=false;
}
else if (errors== 3)
{
GridViewCustomers.DataSource = null;
GridViewCustomers.DataBind();
lblNoResultsMsg.Text = "Please enter correct format of C Number ";
lblNoResultsMsg.Visible = true;
valid=false;
}
else if (errors == 4)
{
GridViewCustomers.DataSource = null;
GridViewCustomers.DataBind();
lblNoResultsMsg.Text = "Please enter correct format of Date of Birth ";
lblNoResultsMsg.Visible = true;
valid = false;
}
else if (errors == 5)
{
GridViewCustomers.DataSource = null;
GridViewCustomers.DataBind();
lblNoResultsMsg.Text = "You need to search by FirstName LastName and DOB ";
lblNoResultsMsg.Visible = true;
valid = false;

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?

This 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.

I 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]....

I have an ImageButton programmed to open up a new window with a small onclientclick javascript routine. But, when the ImageButton is clicked, the page containing the button reloads too, causing both a delay and loss of position on the page. I don't need the page to reload, just the new window to open.

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.
