AJAX :: Two Update Panels Interfacing With External Button - How To Control Button Visibility

Jun 15, 2010

I have a page with 2 update panels

UpdatePanel1 contains a gridview1 and a standard panel, pnlForms. gridview1 has a linkbutton which is processed in the gridview1_rowcommand

UpdatePanel2 has gridview2.

There is also a Submit button that isn't in either UpdatePanel but may be a candidate to go into its own UpdatePanel. The Submit button is a trigger for both update panels

The behavior I would like is:

1-Initially, all visible except pnlForms and Submit button 2- When linkbutton in UpdatePanel1 gridview1 is clicked, pnlForms and Submit button become visible. 3. When Submit button is clicked, both gridviews should be refreshed, and PnlForms and the Submit button should both become not visible. I believe I may have to put the Submit button in its own UpdatePanel3 but am not sure how to proceed.

In my present code, everything works as desired except Submit button (not presently in any Update panel) is always visible. Assuming Submit button is initialized to not visible, how do I get it to appear when I click the link button in gridview1 and to disappear when it is clicked?

Forms Data Controls :: How To Change The Visibility For Update And Edit Button With This Details View

Apr 4, 2010

I have a details view with buttons in the footer. When the user clicks the edit button the calls the ChangeEditMode() method. I want to change the mode of the details view to edit mode which seems to work fine. It goes into edit mode with a text box. I also want it to set the visible property of the edit button to false and set the visible property of the update button to true. Then while still in edit mode the user can click the update button that will call the appropriate method to persist the changes.

I got the changemode() to change to edit but can't change the visible property of the buttons correctly. This is what I have so far. Can some one please tell me what I'm doing wrong?

Setting Visibility Of Button Control In GridView Header?

Nov 8, 2010

I have a gridview that displays entries from a data table. I am giving users the ability to select a subset of the data in the table by having a textbox and search button in the grid view header. The search button fires the gridview row command, and changes the underlying sqlDataSource's select command, and adds the text value from the text box as a parameter.

Also, I have a "Show All" button in the header, that clears out the select parameters, so all entries in the table are shown. Again, this works perfectly.

What is NOT working is controlling the visibility of the "Show All" button control. Below is the html markup for the data grid header template:

<asp:Button ID="btnShowAll" runat="server" CausesValidation="False" CommandName="ShowAll" Text="Show All" />
<asp:Button ID="btnSearch" runat="server" CausesValidation="True" CommandName="Search" Text="Search" ValidationGroup="vldSearch" /><br />
<asp:TextBox ID="txtSearchName" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="vldSearchName" runat="server" ErrorMessage="You have to provide an attorney name to search for." Text="*" ControlToValidate="txtSearchName" ValidationGroup="vldSearch" ForeColor="White"></asp:RequiredFieldValidator>

In the Row Command event handler, here is how I am setting the visibility of the button:

If Not Me.dgAttorneys.HeaderRow Is Nothing Then
Dim btnShowAll As Button = Me.dgAttorneys.HeaderRow.FindControl("btnShowAll")
btnShowAll.Visible = Me.sqlAttorneys.SelectParameters.Count > 0
Trace.Write("Show all status is " & btnShowAll.Visible.ToString)
End If

The trace statement is showing the correct visible status - if the "show all" button is clicked, I do a SelectParameters.Clear() on the sqlAttorneys sqlDataSource.

Is my problem due to a misunderstanding of how the "FindControl" method works - I had assumed my new btnShowAll that I define is actually a reference to the "physical" control on the aspx page, so any changes I make to my local object is reflected in the control on the page.

If this is not the case, what is the best way to get a reference to the button control in the header row of the grid view?

AJAX :: Set The Visibility My UpdatePanel To True Upon A Button Click Event

I'm attempting to set the visibility my UpdatePanel to true upon a button click event (as shown below). It should be rather straightforward but unfortunately it's not working at all. Any idea why it's going wrong?

<asp:UpdatePanel ID="UpdatePanelSearchSubject" runat="server" UpdateMode="Always" Visible="false">

<asp:RadioButton ID="peopleSearch" runat="server" Checked="True"

<asp:RadioButton ID="groupSearch" runat="server" Text="Group"
GroupName="searchSubject" />
<br />
<asp:Button ID="btnGetGroups" runat="server" Text="Search"
OnClick="btnGetGroups_Click" BackColor="#CCFFCC" />
<br />
<br />
<asp:AsyncPostBackTrigger ControlID="btnSearchSubject" />
//code behind

AJAX :: How To Update Gridview Data From Back Button Or Forward Button

Nov 10, 2010

I have a gridview that does a select statement against a sql database. What I want to do is have the data in the gridview refresh upon either hitting the back button or the forward button.

If the back button is pressed it should give me yesterdays data from the table. If I hit the forward button it should give me tomorrows data, at the same time i want the forward button to be limited to going forward only 5 days from todays date. I figure that I have to do this in a Updatepanel however I am unsure as to how to do this.

AJAX :: How To Generate Multiple Collapsible Panels Depending On Button Clicked

Feb 20, 2011

I would like to make a table with 2 columns. The first column would have 4 buttons, and when you click on one of the buttons, some

collapsible panels would appear in the right column. These could be populated from a database. When you see a collapsible panel, it

would have only a few lines of text, but when you clicked the title at the top of the text (still in the panel) the panel would expand.

Is this possible with drag and drop controls, or does it need real programming on my part?

Web Forms :: Visibility Of Panels And UserControls?

Mar 9, 2010

First off - has any recent .NET / Windows Service Pack / Windows Update changed the behaviour around the Visibility of Panels / User Controls? An area of our site has all of a sudden stopped working. The most recent change that I made was a few weeks ago, I've backed out the change from my development environment, but the issue is still happening.

I'll explain what is happening. I have a couple of forms where the same behaviour is happening, but they follow the same pattern:

On the form there is let's say 2 ASP:Panel controls. In each of these there is a separate ASP:UserControl. When the User first visits the page, they are shown the first Panel and User Control. On this control they complete a couple of steps and click Next. This fires an event on the main page, which hides the first panel and shows the second panel, at least that is what is supposed to happen - and if I debug and step into the code this is what is happening as normal. Except on screen, the first panel is no longer being hidden, so it would appear clicking the Next button does nothing.

I'm at a loss as to what has happening - nothing has changed, and stepping through the code it's working correctly, but the screen is not reflecting what is happening in the code.

My next step is to create an isolated set of test pages to recreate the issue. Will attach when done and investigated, hopefully this will solve it

GridView Conditional Button Visibility?

Mar 28, 2011

I have this itemtemplate for a gridview column that is pulling data from a SQL database. My Question is how would I perform a check to see if my field ActivityFile has a value (which means a file is in the db) and then display the LinkButton at which point I generate code to download the file (already done and works).

<asp:LinkButton ID="DownloadFileBtn" runat="server" visible="false">Download File</asp:LinkButton>
<br />
<a href="<%# Eval("ActivityLink") %>"><asp:Label ID="Label4" runat="server" Text='<%# Bind("ActivityLink") %>'></asp:Label></a>

Bind Button Visibility To The Expression (C#)?

May 19, 2010

I have a delete button in each row of GridView (component ASP.NET). I want some of the delete buttons to be invisible. The visibility of the delete button should depend on the data that are back the row.

GridView is backed by EntityDataSource. GridView displays entities called Category, one instance in each row. Entity Category has (besides others) also a field of type EntityCollection. Name of that field is Items. Basically I want to allow user to delete a row only if the Items field of backing Category entity is an empty collection.

This is how the button looks right now:

<asp:Button ID="DeleteButton" runat="server" CommandName="Delete"
Visible=??? ></asp:Button>

I don't know what should replace ???. The button schold be visible only when this expression evaluates to true:

((SimpleEShop.Model.Category) dataItem).Items.LongCount() <= 0

where dataItem variable contains data of current row in the table. What is the binding that I need ?

Forms Data Controls :: Formview Button Visibility Not Working Correctly?

Apr 17, 2010

I have a formview that displays user info from a dropdownlist. One account may have many users, but one account Primary. I am trying to disable the Edit/Delete button in the formview if the selected ID is the account primary. The problem I get is this.

Step 1: page_load - the primary user is displayed by default, but the delete button is enabled - not right

Step 2: I use the dropdownlist to select another user (not the primary) - everything's fine

Step 3: I then select the Primary User, the Delete Button is disabled - perfect

Step 4: select another user, delete button still disabled - Not right.


1. As you can see my sqlSelect Parameters are bound to the DropDownList.SelectedValue, but is t seems like my if statement for comparing selecteduser to varAdminID doesn't work except once.

So to help debug, i added a label control that displays the selected userID, but on page load the label is blank. but it displays the first record on the list anyway. so if this is the reason for not disabling the delete button on page load then why later does it not reable the button when the user is not the primary, and the UserID is displayed on the label and it is not the primary userid?

Javascript - Validation Using AJAX Without Update Panels

Dec 15, 2010

I'm looking for a way to use custom ASP.NET validators to validate input, without using UpdatePanels, and without a full postback. The validators do several things - not just length/regex, but some other non-standard stuff as well. Javascript is required for our users, so I don't have to worry about normal users who have javascript turned off. I see several options, but none are ideal:

1) Suck it up and use UpdatePanels. I'm in the "UpdatePanels are evil" group, so I'd prefer not to do this.

2) Without using validation controls, manually validate the fields by passing the values to a PageMethod static method, via jQuery or any other AJAX framework. This would require client and server coding each time I needed to use a validator.

3) Use jQuery (or any other javascript framework) validation for client validation, then if they somehow get by that, have server-code validation controls for full postback. This would require all of the validation rules to be written in javascript as well as C#. I don't care about the full failed postback at this point, because the javascript validation would catch real users who weren't trying to screw me over.

Is there alternative out there for using real CustomValidator controls, with partial postback, C# code only, for validating input without UpdatePanels and without a lot of redundant javascript?

AJAX :: Update Panels, Repeaters And Lists?

Jun 3, 2010

I realise that there are many posts on update panels and repeaters but none that quite solve my problem. I have a page with two Repeaters each inside seperate update panels. They sit next to each other one on the left and one on the right. The left repeater is filled from my database on my page load event. Im am storing the data in a List<> and then binding the list to the repeater. This works correctly and displays all my results. Each item in the left repeat has a button aswell. The button needs toremove the data from the left repeater and place it in the right repeater. I only want the database to be accessed in the Page_Load and then never again during the use of the page, until the data is saved (I have not got to this feature yet). So I have decided to use List<> objects.
