Changing Visibility Of Panel Inside Formview?
Dec 28, 2010
I have a panel inside a formview that is supposed to become visible when a checkbox (also inside the formview) is checked. I am able to access the controls, but I'm not sure how to actually make it work. This is my codebehind so far, I know it's not right, but it gives a basic idea of what I'm trying to do.
Protected Sub FormView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView1.DataBound
If FormView1.CurrentMode = FormViewMode.Edit Then
Dim checkGenEd As CheckBox = FormView1.FindControl("checkGenEd")
Dim panelOutcome As Panel = FormView1.FindControl("panelOutcome")
If checkGenEd.Checked = True Then
panelOutcome.Visible = True
Else
panelOutcome.Visible = False
End If
End If
End Sub

I'm trying to change the visibility of a imagebutton to false, if the imagebutton.ImageUrl="". The problem is that the imagebutton is inside "ListView2", and "ListView2" is inside "ListView1". Who can I do this in vb code... or even a javascript.

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?

I need to achieve an effect of a read-only textbox, where when the user clicks on the textbox a popup grid control appears, after the user has made a row selection the text box is populated.... Looking at the AJAX Toolkit model it seems like a CustomExtender would be the way to go, but I can find no documentation on how to build such a thing, so I am looking at improvising.
Here is my process (which is still not working):
Using either an ASP.NET TextBox or HTML <input type="text" runat="server"> control I need to able to trap on the onclick event and then set an ASP.NET Panel control Visible="true". I have tried placing my GridView control inside a <div> and using style properties to set it to hidden and using a client-side (javascript) event handler on <input type="text"> onclick event setting the style property to visible, this does not work correctly. It results in a empty place-holder like grid that popualtes on click (I suspect this is because the DataGridView lives inside a ASP.NET Panel)
I would like to be able to call a server-side method from inside my client-side JavaScript function. I seem to recall from Microsoft AJAX 1.0 docs a way to RegisterClientScript or some approach that allows this and can not find anything on this being supported with the ControlToolkit/MS AJAX 2. If I can do this I could set my ASP.NET Panel Visible property to true and then call Update() on it's UpdatePanel parent which should give me exactly what I'm looking for.

I have always used VB for my .NET programming but have recently migrated to C#. I have a really basic problem that I don't understand and am hoping someone can point out why I'm having this issue.
I have a panel which has visible = false by default. Upon a click event of button, it checks current visibility and sets true / false based on current value. I'm getting the above error with the following code, but do not know why. The same code works in VB!

aspects of some controls in Code Behind (VB) with controls inside a datalist and/or repeater. I have read a lot of stuff on using some tricks but none seem to work so far. I am new to ASP.net so some of the explanations are too cryptic as well. Below is a section of code that I am trying to change. This example is attempting to make the label visible if the dataitem is true and hidden if false. No matter what I seem to do I cann't reference this label to change. I also want to change the text on some other controls in this dataitem if the returned value is a certain value.

I have the following (abbreviated) code:
<asp:FormView ID="FormView1" runat="server" DataKeyNames="ItemID" DataSourceID="LinqDataSource1">
<EditItemTemplate>
<asp:DropDownList ID="ddlCategory" runat="server" SelectedValue='<%# Eval("Category") %>'
DataSource="<%# GetCategories() %>" DataTextField="Text" DataValueField="Value" />
</EditItemTemplate>
<ItemTemplate>
<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<InsertItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</InsertItemTemplate>
</asp:ListView>
<ItemTemplate>
</asp:FormView>
When the FormView is in Edit mode, ddlCategory is populated as expected by calling GetCategories(), which returns a List of categories. However, when the ListView is in Insert mode, ddlCountry is empty. I put a break point in GetCountries(), but it never gets called. If I change the name of the method, I get an error. So it recognizes the method at compile time, but does not call it at run time. I'm guessing this is an embedded binding issue of some kind, but I'm hoping someone can save me a lot of time by pointing out the solution.

After I use FormView in InsertMode and the record is added, I want it to switch directly to EditMode.
I assume I would place this command in this action:
protected
void FormView1_ItemInserted(object sender,
FormViewInsertedEventArgs e)
However, I can't find the correct command to issue.

I am having trouble wiht my AJAX collapsible Panel Extender. I have the CPE opening a panel that contains the Table of Contents of a document being displayed on the page. A user clicks on the link for a certain part of the document, the event triggers a C# function that gets the file that particular section is contained in an displays the section. Right now you have to, of course, click on the TitlePanel to open and to close the CPE. What I want to do is have it close automatically whenever a link inside the content panel has been clicked. I have tried placing this.cpeTOC.Collapsed=true; in the functiion that gets the files but it does not work. I have also tried the autocollapse property of the CPE and it just collapses whenever someone moves thier mouse from the titlepanel.

I have created a FormView whose defaultmode = "insert". When loaded the FormView displays the InsertItemTemplate. At the top of the page is a DropDownList used to select Clients. I have added a list Item to the DropDownList with value = "0" and text= "Select Client" option. So the Page is in Insert Mode. SO FAR EVERYTHING IS AS EXPECTED.
When I select a Client from the DropDownList, the page remains in Insert Mode (Don't understand why? ) Could it be the default Mode setting? So I added the following vb code.
Protected Sub ddlSelectClient_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlSelectClient.SelectedIndexChanged
If ddlSelectClient.Text <> "(Select Client)" Then
If FormView1.CurrentMode = FormViewMode.Insert Then
FormView1.ChangeMode(FormViewMode.Edit)
End If
End If
End Sub
So after an existing Client is selected, the FormView Mode should be changed to EDIT. AND INDEED THE EDIT ITEM TEMPLATE IS DISPLAYED.
Ah but life is not so simple (after all this is a Microsoft Application). So I enter data in some fields and click the [Update] Button.
Then I get the following message:
FormView 'FormView1' must be in edit mode to update a record.
THe FormView displays the Edit Template, the Update and Cancel Buttons are displayed. All this should mean I am in edit mode.
Just call me FrankenSoft !@#$%^^& or is it MicroStein?
Oh by the way I'm using Linq to SQL data sourcess. Should I be? I'm having a lot of problems with the FormView using Linq.

I have a column value on a Formview and I want to change it at the last second to a programmatic value.
So I created this function to work on ItemUpdating so that the value of one of the formview fields could be changed programmatically to a constant I do a response.write value to make sure there is something in there. However, checking the database, the only getting written is null:

In an asp.net 3.5 web app, I have a page with the following markup/code (this is the brief version, but I believe I got all the relevant info).
[Code]....
The form contains 2 different record types, accessed using the paging controls, depending on the ParentSR field; a parent SR will be something like '1234' while its sub-record will be something like '1234.1'. There are only a few differences in the fields used between the 2 different record types and that is why they are stored in the same table. However, the activity depends on the record type. When browsing from the parent record to the sub-record, the itemtemplate loads fine (notice in the formview's datasource
query, that the sractivity_id field is being pulled along with the subquery value). But when going to edit the record, the page throws an error:
System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.ArgumentOutOfRangeException: 'ddlActivity' has a SelectedValue which is invalid because it does not exist in the list of items.
If i click 'back' and retry, it may take 3 attempts, but then the edittemplate will load just fine. I should also point out that this error does not always occur. I've been trying to figure this out for a couple months and it is driving me nuts, mainly due to the fact that I can't reproduce the error in development--it seems to only occurr in production. Anyone with any thoughts on what is going on?

I have a literal inside each datagrid item. When the datagrid binds I set the literal equal to a small javascript script (a third party source). It works great. when I update my update panel the javascript is lost. I know this is a known issue. From googling they recommend you use:
ScriptMananger.RegisterStartupScript
However this renders the javascript at the bottom of the page. I need it inside my datagrid items. Is there a way that I can register my javascript to my literal control?

I am using an update panel in my ASP.NET code. My problem is very simple and straight forward.
There is button which send some group SMSs to different users.
I used update panel to show UpdateProgress on my page.
On click of the button I wish to hide the button and some other labels on the page.
The problem is that after clicking the button everything else works find but these control's state does not change.
Funny thing is when i click the button, it does some checks and update a label text with error resultant values, if error is there. It works fine.
But after removing the error, I click the button once again to do the processing. Then everything on code works fine, but the label which was showing doesnot hide.
Code is as follows:
ASP.NET page code:

Server side code:
