using Multibinding.StringFormat in codebehind

Posted By:      Posted Date: October 07, 2010    Points: 0   Category :WPF

I have this application that has dynamic language switching built in. Based on the selected Culture, strings throughout the application will change. Translated strings and their original values come out of resource files. I use bindings to attach the resource values to buttons, labels, etc. Most of this binding occurs in the code behind.

I've been able to concatenate localized strings with data using the Binding.StringFormat property... such as...


mybinding.StringFormat = "# {0}"


for "# of items". My problem is that I now need to concatenate two (or more) localized strings in the code behind. I quickly realized I could use MultiBinding and add my bindings to it, keeping with how things currently work, however, using MultiBinding.StringFormat doesn't seem to work. I'm trying to use myMultiBinding.StringFormat = "{0} {1}"; to insert a space between the two binding values, but it just appears blank when bound to the "Greetings" Label.


Binding b = GetBinding("HelloWorld"
Binding b2 = GetBinding("Name"

Extreme ASP.NET: Codebehind and Compilation in ASP.NET 2.0

ModalPopup/UpdatePanel from codebehind, inconsistent behavior onClick


First post bear with me please:

I have a simple form with a list of linkbuttons, each fires the same onclick event which sets an indicator image.  I have a dummy button with style="display:none" which I have set as the TargetControlID of the modal.

onClick event from the imagebutton, the modal is shown via modal.Show().  The cancel button inside the modalpopup fires an event which turns off the indicator image and hides the modal via modal.Hide(). 

The events fire perfectly, it's very simple!  Although after doing some testing I noticed the modalpopup is not presented after the 6-10th cycle of clicking the open event, then clicking cancel.  The grey background appears but it is behind the main panel and the modal is either presented behind this or is just simply not displaying. 

I spent hours researching various methods, implemented the CancelControlID to see if it was somehow tied to my call of modal.Hide() that fails.

This occurs with an updatepanel only.  The behaviour is much cleaner this way, so I would hope to be able to implement this.  I have basically eliminated everything but these two events!  Please help

Binding with objects using codebehind



How can I bind an object to a dropdown list or gridview ? I am writing an application where my code behind calls an instance  and bind the list to either dropdown or gridview.

For example:

.aspx page:  default.aspx

<asp:dropdownlist  id="dd1"   runat="server" />



Code Behind:  default.VB

Partial Class Services_Default

    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As   System.EventArgs) Handles Me.Load

      Dim objlist As New services()

         Dd1.datasource = objlist.GetServices()

         Dd1.datatextfield = ?

         DD1.datatextfieldvalue = ?



End sub


End Class



APP_CODE :  Service.VB

i am trying to replicate the following sequence: input text into text box > press search button > search a database using LIKE operator > display using a gridview or listview. this sequence is fairly easy to do using the drag and drop then sqldatasource options, but i am trying to do the same result using a codebehind.  here is my code:   ____________________________________________________________________________________________________________ SqlConnection myConn; myConn = new SqlConnection(@"Data Source=.\SQLEXPRESS; AttachDbFilename=|DataDirectory|\projectDB.mdf; Integrated Security=True;User Instance=True"); myConn.Open(); string strSQL; strSQL = "SELECT * FROM Message";       //strSQL = "SELECT * FROM Message WHERE Message LIKE '" + txtSearch.Text + "'"; SqlDataAdapter da = new SqlDataAdapter(strSQL, myConn); DataSet ds = new DataSet(); da.Fill(ds, "Message"); GridView1.DataSource = ds; GridView1.DataBind(); myConn.Close(); _____________________________________________________________________________________________________________  now, if I use this code inside a page_load event, it does work. if I put it inside a button_click event i get nothing. i am mystified by this.. any help? why can't i use a button to display my gridview1 when i'm using a code behind.

FormView EditItemTemplate DropDownList loaded from codebehind via stored procedure

I'm attempting to load DropDownLists from the C# codebehind as the FormView switches modes to Edit and displays the EditItemTemplate.  I present the data in a FormView ItemTemplate using text boxes.  When the user selects Edit, I have been attempting to load the EditItemTemplate dropdownlists by creating a dataset and binding it to the control, without success.  I've successfully loaded them in previous projects from within the .aspx code using <asp:ListItem> and within the C# code behind using Control.Items.Add(new ListItem), which are essentially the same thing of course .  This project is different in that I want to get the data from a stored procedure on a MSSQL server. In my latest attempt, I can see the data in the datasets.  I'm getting "Error connecting to database.'eitRace' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value" I include the code below.  If someone could point me to an example I would be greatful.  There has to be an elegant way of accomplishing this.

Can't access a control in a listview layout template with codebehind

While running ItemDetabound upon load of a listivew, I am trying to access the text in a label of the LayoutTemplate of a different Listview.  It works fine if I try access the same labels under the same names if they are in the same listview, but not if they are in a different one.  It was working for a while, can't figure out what I changed, but now says that object doesn't exist.   Here is the html code for the labels: <LayoutTemplate> <table ID="Table2" runat="server" cellpadding="0" cellspacing="0"> <tr ID="Tr1" runat="server" style="padding-left: 0px"> <th ID="Th1" runat="server" style="text-align: left; white-space:nowrap; "> <asp:Label ID="Label1" runat="server">Label 1</asp:Label> </th> <th ID="Th2" runat="server" style="white-space:nowrap; width: 150px" >
