Here is my code

When I run the page, the listbox was truely enabled when I unchecked the checkbox. But when I tried to update on the server side the listbox is still disabled and couldn't find the selected items.

Forms Data Controls :: How To Disable Button Inside EditItemTemplate Inside DetailsView

Jan 20, 2011

I have a boolean / bit value in the database called "is_paid". Depending on this value I want to Disable a button. (the same would go for example to set a textbox not Visible, but anyway)

What I want is to Disable the button, if my boolean is 1 (true).

First I tried to convert my boolean value to text:

<asp:Button
ID="btnCalculatePayment"
runat="server"
Text="Submit"
onclick="btnCalculatePayment_Click" Enabled='<%#
Convert.ToBoolean(Eval("is_paid")) ? "False" : "True" %>'
/>

But got an error:

CS0030: Cannot convert type 'string' to 'bool'
However, if I use it one a Label it works fine: <asp:Label
ID="lblIsPaid"
runat="server"
Text='<%#
Convert.ToBoolean(Eval("is_paid")) ? "True" : "False" %>'></asp:Label>

So another trial I did was to CAST the data from the database to be the text that I want, like so:

SELECT not_paid = CASE WHEN is_paid = 0 THEN 'True' WHEN is_paid = 1 THEN 'False' END ....

And my code changed to:

<asp:Button
ID="btnCalculatePayment"
runat="server"
Text="Submit"
onclick="btnCalculatePayment_Click" Enabled='<%#
Bind("not_paid") %>'
/>

But got this error:

System.InvalidCastException was unhandled by user code
Message=Specified cast is not valid.
Source=App_Web_absjd3ob
StackTrace:
at ASP.manager_aspx.__DataBinding__control74(Object sender, EventArgs e) in c:Documents and SettingsAdminMy DocumentsVisual Studio 2010ProjectsWebManager.aspx:line 219
at System.Web.UI.Control.OnDataBinding(EventArgs e)
at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding)
at System.Web.UI.Control.DataBind()
at System.Web.UI.Control.DataBindChildren()

So I wonder, is it possible to change the "Enabled" property based on by boolean value?

Forms Data Controls :: Using ListBox Within DetailsView?

Nov 16, 2010

I have a detailsview which is used to input data into an SQL database. Some of the fields contain drop down menus which are populated from the database.

I also have a form that allows the user to select mutiple values from a listbox (populated from an sql database) by moving the required items from one list box containing all the available items into a second one containing the selected items. There is also a text box which is used to filter on the available items. When this is passed through to a stored procedure to be put into the database, it is passed as a comma delimited string containing all the selected values.

This works fine on a separate form, however I would like to include it in one of the fields of the detailsview. This creates a BC30451: Name 'ListBox1' is not declared error. I have looked for hours on the internet to try and resolve this but cannot find what I need for how to declare the list for use within the detailsview.

Here is the code for both the working multiselect form and the code for when I have tried to integrate it into the detailsview:

.NET Gridview InVB - Enable Or Disable The Textboxes And The Dropdown Listbox If The Row Is Not Selected

Mar 9, 2010

I have a Gridview that has a button at the left hand side representing the row number. The Gridview has two textboxes and a dropdown listbox as templates. I would like to enable or disable the textboxes and the dropdown listbox if the row is not selected. I also need to enable or disable the templates depending on what the value is of one of the cells. When the templates are changed, I need to save the changes.

I have been able to get this working in the RowDataBound Sub but not in the RowCommand Sub when the row is selected. provide an example in VB.My current RowDataBoundSub, which does no work is below:

Protected Sub PropGrid_RowCommand(ByVal sender As Object, _
ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles PropGrid.RowCommand[code]....

My current RowDataBound Sub, which is working is below:

Protected Sub PropGrid_RowDataBound(ByVal sender As Object, _
ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles PropGrid.RowDataBound [code]....

AJAX :: Editing Image Inside DetailsView Inside UpdatePanel?

Oct 4, 2010

I'm trying to add and edit an image which is located in a detailsview which is inside an UpdatePanel. After I read relevant topics in the forum I installed the Ajax Control Toolkit. Below is my source code. When I used it only for insert new image it worked great. The problem caused when I tried to implement it on the Edit mode, i.e. when I tried to edit the image and upload a different image. Unfortunately it didn't work as I hoped. Nothing happend and the image hasn't been changed. I also tried to change the IDs (AsyncFileUpload ID) to be the same in both places but it didn't work either.

The source code:

<asp:DetailsView ID="dvMovie" runat="server" Height="50px" Width="695px"
AutoGenerateRows="False" DataSourceID="sdsMovieById"
BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" [code].....

Forms Data Controls :: Selecting The Index Of A Listbox Inside An ItemTemplate?

Mar 23, 2010

I have a listBox that is bounds its content from the database. This control is inside an itemTemplate. When the item template is boudned, I want to select the corresponding value.

I have this ugly single line of code:

[Code]....

What it does is to select the right value to a ListBox that is databinded with values inside a DetailsView

here is the rest of the code:

<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" DataKeyNames="ID" DataSourceID="SqlDataSource4"
EnableModelValidation="True" ondatabound="DetailsView1_DataBound">
<Fields><asp:TemplateField><ItemTemplate>
<asp:ListBox ID="lbATechAuthCheck" runat="server" Width="100%" DataSourceID="SqlDataSource2" DataTextField="status" DataValueField="id"></asp:ListBox><asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:myConnectionString
%>"SelectCommand="SELECT * FROM [Status]"></asp:SqlDataSource>
</ItemTemplate></asp:TemplateField></Fields></asp:DetailsView>

Is there an easier way to achieve the same thing perhaps without any code behind?

Web Forms :: Javascript To Set The Scroll Bar In A ListBox?

Jan 20, 2011

I have a custom C# created listbox. This listbox is a multiple select listbox. Unfortunately, the client I am working with wants it to populate with customer data. This returns well over 20k options. I am getting this from SQL. So the list is dynamic, depending on the customers in the table in SQL. The list is ordered alphabetically by the customers last name. So Jim A would be first and Tony Z would be last.

The problem I am having is that the list is so large, and needs to stay at around 100px in height, it is damn near impossible to navigate (think watching an hour long youtube video, clicking a millimeter and skipping like 10 minutes of time). Sorting through the entire list would take a little longer, but, I can always add a loading jquery pop up for the second or two it would take. I already added a row of A-Z links to the bottom out of the listbox control.

Inside my if is where the magic needs to happen. Anybody know of a way to scroll to that value? I cannot imagine it would be this difficult. I tried selecting that value, then item.scrollIntoView() then deselecting that value. I do not want to select the first value, but rather just scroll to it. (think like an ipod touch songs list). Is there anyway to find the scroll bar position of the particular item then scroll to it?

Javascript - Add / Remove Items From One ListBox Control To Another ListBox Control?

Oct 10, 2010

I'm moving itmes from one ASP.NET ListBox control to another ListBox control from client-side. It works on the client-side but when I tried to count items in destination ListBox on the server-side, it's always nothing. Below, is the jQuery code used to add/remove items from ListBox control.

[Code].....

I know that we can add/remove items from ListBox from server-side. But I'd like to get it done from client-side. Why there isn't anything in the destination ListBox when counting the items from the code-behind, eventhough the items are added from the client-side already.

.net - Cannot Disable Or Enable An Exchange Mailbox Running A Powershell Command Inside C#?

Mar 14, 2011

I have a couple of powershell command that are very simple.

disable-mailbox dadelgad -confirm:$false
enable-mailbox -identity 'dadelgad' -database 'NET5014DB10' -Alias 'dadelgad'

The first command is to disable an exchange mailbox and the second enables the mailbox. I am logged in as a user who is in the Organization Management group which has full admin priviledges to Exchange but is not a domain admin. If I run these commands directly in Powershell, they work fine but they do not work when called from C#.

I created a very simple windows forms app that has a couple of buttons that invokes these commands from C# code. Running the app as the user with full Exchange right, most commands work with no problem such as get-mailbox -identity 'dadelgad'. I can set flags in Exchange, add alias emails and do most functions but I cannot disable or enable an account.Do I need to be a domain admin to do these functions. It almost seems like a permission issue but the user has full rights to Exchange and can perform both of these commands directly in Powershell.
