How to change the language based on log in user programmatically in SharePoint

User Controls are great in ASP.NET. They let us divide the page into small sections. You can easily use User Controls on a ASP.NET page by simply dragging and dropping the control from the solution explorer. Sometimes we need to load the User Control dynamically. In this small article we will learn how to load the User Control dynamically.

This article is taken from the book C# in Depth, Second Edition. This segment looks at what it means for code to be dynamic, and the syntax involved in using dynamic typing in C# 4

Hi, I have a website that I need to add some dynamic data from asp.net, I'm completely new to .net and am having some problems (usually a php user).

K so, I have
a simple html tag
<a href="" title = "" >my link</a>

Now all I want to do is to insert some data in to the href and title parameters. in php I would just use <a href="<?php echo myHrefvar?>" title = "<?php echo myTitlevar?>" >my link</a>

I've tried doing
<a href="<% = myHrefvar%>" title = "<% = myTitlevar%>" >my link</a>

and in my default.aspx.cs I have the variables being set
string myHrefvar = "my href";
string myTitlevar = "my title";

but it always gives the message that they're not linked.

Have also tried
<a href="" title = "" ID=Req1>my link</a>

and in the apsx.cs file
Req1.HRef = "sdsdsd";
Req1.Title = "sdsdsd";

but again I get an error saying Req1 doesn't exist in the current context.

So help, I'm missing something rather fundamental here, any help would be much appreciated.

Hi,

I have a user control which has a modal popup. This modal popup has a grid and few controls like textboxes and comboboxes. I am trying to clear out all the controls when the close button is clicked. I am using javascript to close the modalpopup. but to clear the controls, $get('<%=txtbox1.clientID%>') method is returning null. can someone please help me?

Here is my code snippet.

function close_Click() {
    var mdlPopup1;
    mdlPopup1 = $find('modalPopup');
    mdlPopup1.add_hidden(clearInputFields);
    mdlPopup1.hide();
    
}

    function clearInputFields() {
        var name = $get('<%=txtName.clientID%>');

        name.value="";
       }

Hello,

Got a problem that I do not know what is going on (using c# and .NET 2008):

I have a main web page and added a user control inside it. The user control has some textboxes. The problem I have is when I populate the textboxes with the data that is in the DB, they do not show the values. The strange thing is If I change the property of textboxes ReadOnly to TRUE, they show the values. The problem is that I need them to be ReadOnly=FALSE.

Could anyone do help me please?

Thanks,

Marco

The values in one of the fields in my GridView's table are just either a zero or a one or a null. Well, "zero," "one," and "" are not very appropriate values to display to the end user. Is there a way I could change these to "True"/"False"/"NA" or "Yes"/"No"/"NA"?

This should not be to hard but my head is not going for it today

I have a gridview that changes the sales reps name every 3 rows.

The data is group in 3 rows for each rep. estimates, job & invoices each have their own row

I want to change the backgroup for each rep.

I am using C# and I would guess it would be in the code behind file

I got this far but can not remember a way to check the next row to make sure

it is the same of changed from the previous row

protected void gvSaleReport_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
           string prevRep;
           prevRep = e.Row.Cells[0].Text;
           if (prevRep == e.Row.Cells[0].Text)
                e.Row.BackColor = System.Drawing.Color.Blue;
            else
                e.Row.BackColor = System.Drawing.Color.White;
        }
    }

Thanks

Hi Community

    I have a GridView that you can add a record to programmatically.

    The problem is that you can only add one record to the GridView after that
it will not accept anymore records. 

    The error is:

NullReferenceException was handled by user code
Object reference not set to an instance of an object.

     Below is the code:    

<body>
    <form id="form1" runat="server">

Hi Community

    In my table I have 3 fields:

 [inFrmDate] (this is the key field), [inFrmData], [totFrmData] (this accepts nulls)

When I try to add [inFrmDate], [inFrmData] to the GridView I get the message
to the effect that the:

    @inFrmDate scalar is not declared.

But as you can see from below it is declared: 

    <asp:SqlDataSource
        ID="SqlDataSource1"
        runat="server"
        ConnectionString="<%$ ConnectionStrings:nuConnectionString %>"
        SelectCommand="SELECT [inFrmDate], [inFrmData], [totFrmData] FROM [tblForms]"
        InsertCommand="INSERT INTO [tblForms] ([inFrmDate], [inFrmData], [totFrmData]) VALUES (@inFrmDate, @inFrmData, @totFrmData)"
        UpdateCommand="Update [tblForms] set inFrmData=@inFrmData, [totFrmData]=@totFrmData where [inFrmDate]=@totFrmDate"

        DeleteCommand="DELETE FROM [tblForms] WHERE [inFrmDate] = @inFrmDate">
        
    </asp:SqlDataSource>
   
    <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false"
    DataSourceID="SqlDataSource1" DataKeyNames="inFrmDate" ShowFooter="true"
