Asp.net - Refresh DataGrid And DropDown On Main Page After Hiding Modal Popup?
Dec 7, 2009
I am adding records to a database from a modal popup. After hiding the modal popup, the page has not been refreshed (even though I have Re-bound the controls). I have reviewed a few postings on the web about this but the solution still evades me. I have attached my code after removing some of the extra detail.
It seems I need to cause a postback, but I don't know what needs to be changed. Some posts have talked about the extender being misplaced.<asp:Content ID="Content1" ContentPlaceHolderID="Head" Runat="Server">
<div class="divBorder">
<asp:DataGrid id="dgrSessionFolders" runat="server" BorderWidth="2px"
BorderStyle="Solid" BorderColor="#C0C0FF"
[Code]...

I have a modal popup extender on a parent form (called from a child aspx is in an iFrame). I'm able to show it by calling
parent.ShowModal();
Which is a javascript function on the parent page that executes $find('ModalPopupExtender1').show();
It works great. But now I've discovered a new problem.
After the VB code-behind is finished executing on the child page, I'd really like to hide that modal form. Don't get me wrong, I have nothing against modal popups. I rather like them in fact. It's just that my users would like it better if they could continue working after the VB code-behind (child page) is finished executing. I tried
ParentForm.ModalPopupExtender1.Hide()
Top.ModalPopupExtender1.Hide

However, I am not using a gridview so editing is not as simple as an edit within a gridview. The modal popup disappears when I click on the edit button. Here is what I have so far, but in the codebehind I get an error saying that my modal isn't declared.In the image below, the little pencil image next to the close button is what I click on to edit the description. When I click on it, the modal disappears, so I cannot edit the text.
<!-- Descriptions -->
<asp:TabPanel ID="tab2" runat="server" HeaderText="Descriptions">
<HeaderTemplate>Descriptions</HeaderTemplate>

I want to wait for and close a modal form (a popup) from another application, as soon as it appears. I want to do this from VB.NET, but suggestions in C# should be easily translateable.
I can hard-code the modal popup's caption in my app, since it's long and unique. What I want to do is simulate either the user clicking on the close ("X") button on the form, or a click on the defeault, tab-order 0 button of the form. Either would work.
Maybe I need more info about the modal popup other than the title bar's caption? In any case, it's safe to use it as an unique identifier of that modal form. I also want that code to terminate checking as soon as the first event of closing the popup happens.
I believe it's trivial, but I can't find any ready info on that. Microsoft says I should not send WM_CLOSE to the modal popup, since it will call DestroyWindow() instead of EndDialog(), but to be honest I don't even know what "sending WM_CLOSE" to the "window" means =/

I have a gridview that appears in a modal popup that is generated dynamically and is bound to a dynamically generated SqlDataSource. I did this to hopefully take advantage of the gridview's automatic editing capabilities. My problem is that when the edit button is clicked the modalpopup closes due to a full postback in spite of the fact that my gridview is in an update panel. I looked at solutions here and here but neither fixed the problem. I've also tried every combination under the sun regarding the positioning of the ModalPopupExtender in relation to the update panel etc, and have tried changing UpdateMode to conditional as well.
Markup:
<span class="none"><asp:Button ID="btnDummy" runat="server" Text="Dummy" /></span>
<ajax:ModalPopupExtender ID="mpLabel" runat="server" TargetControlID="btnDummy" BackgroundCssClass="modalBackground" PopupControlID="pnlLabels"></ajax:ModalPopupExtender>
<asp:Panel ID="pnlLabels" DefaultButton="btnOk" Style="display:none;" runat="server">
<div style="background-color:#fff;border:1px solid black;padding:7px;">

I have a modal popup that allows an admin to choose from a variety of checkboxes to add features to a specific product. If there is a checkbox that an admin believes should be available but isn't because that feature is not in the database, I have added a textbox so that user can add a new feature to the product.
Once I added the textbox, it stopped allowing inserts. At first it was in the same If Else as the checkbox for each loop, but I have recently changed it so the textbox is in it's own for each loop. I have an underline under the words txtFeature.Text that says Value of type 'Char' cannot be converted to 'System.Web.UI.WebControl.Textbox.'
vb code:
For Each feature As ListItem In cbxAddFeature.Items
If feature.Selected Then
Dim strSQL As String = "INSERT INTO Marketing

I have a problem I am trying to set the parent textbox from the modal popup.
Although I found the control from the modal popup with the below code
DirectCast(Parent.Page.Form.FindControl("ContentPlaceHolder1").FindControl("myAccordion").FindControl("txtTo"), TextBox).Text = str
This is being called on button click when the user has finished selecting from the Checkboxlist.
When the parent page is shown again though the textbox is empty.
The scenario of my user control is that a user is to select from a checkbox list which is a list of emails.
When done has been clicked then it is required that the selected emails be forwarded to the parent webpage.
Then the To Textbox in this case will be filled with the emails that the user has selected.

I have a data grid on my form with 6 columns. 5 of the 6 are combobox fields. When just looking at the datagrid all the drop down buttons on the left really clutter up the grid. Does anyone know a way to hide the drop down button on the combo box until the time the user actually clicks in the cell. I have tried changing the style to flat which helps but I would rather it wasn't visible at all until the user is actually in the cell.

VB.NET Winforms Application... When a user starts typing in the search box of the application it automatically populates the name list dropdown box with the valid results and sets the droppeddown value to true... Everything is working fine except the fact that the user is forced to select a value from the name list or press the esc key because without doing so the mouse cursor just disappears and you have to move the mouse all the way outside the application for it to come back and it will only do so while outside the applicaiton.. Below is the code that I am using for this and it should be noted that I am using the droppeddown value else where in the application and none of those instances have an issue its only this one..
Private Sub u_lastName_Box_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles u_lastName_Box.TextChanged
u_nameLook_Box.Items.Clear()

I have a asp grid with a few columns that bind to data. The last column has been converted to a template-field. In this template-field is a button with a modal popup extender attached to it. Hidden inside this field is a modal popup. This modal popup is used to add a new account. it contains 2 text boxes, drop down lists and buttons("Add" and "Cancel"). When "add" is clicked the modal should close after the inserting of the new account in the code behind.
The Problem: I get the popup to display and load the Drop down lists from the cache, without problem. How do I get the button click event to fire in the code behind. I've tried using a JavaScript function that performs a _doPostBack('btnAddAcc','') but it keeps returning the error "JavaScript error: Object expected". I gathered after about 1 hour on Google that it is because "btnAddAcc' is not found because it is actually within the grid-view cell and can't be directly accessed. Using page methods and ajax calls is a last resort as the company has a strict policy against this and only allowes this after a bunch of paperwork.
The Code:
<asp:GridView ID="gvNEA" runat="server" CssClass="gridA_Orange"
AutoGenerateColumns="False" AllowPaging="True"
EmptyDataText="No transactions with 'Non Existent Account(s)'"

the client has asked for all forms and classes to be hidden from the main project, so when he sells it, they will only be able to see part of the project and not all the classes and forms.My Solution: I have created another project called project2, and added all the forms and classes from main project, fixed all errors and compiled it.I deleted all the forms from the main project and added a reference so that it gets all the forms from the other project by referencing the dll file, but it does not seem to work and get a lot of errors.is there an easier way of hiding the forms and classes from the main project or do I need to do more then just add the reference.

I have a datagrid who's ItemsSource is a strongly typed IEnumerable object In this datagrid, I have a checkbox column, a price column, a part name column, and a 'total selling for' column. On checking the checkbox I need to update the total selling for column with the value in the price column. This part I have working, however, how can I get the checkbox to remain checked when this happens?

Using vb.net. I've got a main form that displays when application is opened. A popup form can then be opened. If there are other windows opened on the desktop, for example windows explorer, then when the popup form is closed, the main form gets hidden behind windows explorer. You have to move windows explorer out of the way to get to the main form. Is there a way to keep this from happening?

I'm having an interesting issue that I can't reproduce on a different project, but can consistently on this one. I have no clue what might be causing it, but am hoping that someone may have seen it before.
I have a main form, from which I run a series of checks. On this form, I have a listview control. Because of some issues with the refreshing of this listview control, I had to create my own messagebox. It's just a form that displays some text ( it also happens to look nicer than MsgBox; in my opinion, anyways ). It's been working great for months, until recently.
My problem is that on my main form's load event, I run this check, which returns an error within a try/catch block. I then call my custom messagebox with a message. It in turns calls it's ShowDialog() function.
In any other situation ( after the main form has been loaded ), I have no problems. The messagebox goes on the screen and behaves appropriately ( ie: waits for my input and acts as a modal dialog ( stops execution of my main form's thread ) ). However, on this onload event, my messagebox comes up and goes away almost immediately afterwards.
I've traced it all the way to the showdialog() call. For no explicable reason, it appears to skip right over this call, without me doing anything on the form.
Here's what the inner trace looks like ( when I put a breakpoint on the onclosing event for this messagebox form ):

I'm planning on a private software, that I wish that have multiple pages, like a installer. It will not be a installer or anything, and I don't want to use tabs on it (it doesn't fit to what I'm thinking.) How can I do it? I've tought on multiple forms, but I don't see how can I load another form while I hide the current 'on-the-fly'.
