How to insert dynamic data into an XML or HTML format table


Hi there,

I have a technical problem as the title described. I need to achieve this by SSIS that means the destination file could be XML or HTML. However, before inserting dynamic data from source, an XML or HTML format table must be predefined. In the final destination file, the predefined table and dynamic data will be both output.

Can anybody give some suggestions or reference links regarding to this? Appreciate it.


Creating dynamic elements in an html table


I need to create 3 buttons in addition to 2 text values (which come out fine) in a row for a table.

However, the buttons are coming out as straight input text fields even though I specifiy  "button" as the type for the td attribute.

Below is my js.

How can I set up these buttons as actual buttons instead of input text fields? Notice the boldfaced code below which is coming out as just input text boxes instead of buttons.

    var tr = document.createElement('tr');
    var td1 = document.createElement('td');
    var td2 = document.createElement('td');
    var td3 = document.createElement('td');
    var td4 = document.createElement('td');
    var td5 = document.createElement('td');

Need help regarding C# / AJAX Dynamic Controls creation


radiobuttons is assigned before page init.. 

public partial class Default : System.Web.UI.Page
//Assign values as a specific Dynamic WebControl Creation.
List<RadioButton> radioButtons = new List<RadioButton>();
List<CheckBox> checkBoxes = new List<CheckBox>();

Then I created a class that would dynamically create a table containing the available flights depending on session.. (See CallPageLoad())

The placeholder and button is inside the UpdatePanel...

on the button inside the update panel, (btnSelect)

i have this code which works... 

protected void btnSelect_Click(object sender, EventArgs e)

Label1.Text = Convert.ToString(radioButtons.Count);

It detects the number of radiobuttons that were dynamically created...

But when I use the following code inside the BtnSelectClick event...

//PLS HELP.......
foreach (RadioButton button in radioButtons)
if (button.Checked == true)
Label1.Text = "You select... " + button;



It does not work even though t

Regular Expression to Match


Here is the kind of text I want to match via a regular Expression

The id="dgSchedule" is always present in the TAG but its location may differ

The table is span over multiple line/contains white spaces/tabs...

I have the regular expression to match the start and end tag respectively over a single line

\<table .*\>


The problem is to match the whole table span over multiple lines

<table cellspacing="0" rules="all" border="1" id="dgSchedule" style="border-style:None;height:100%;width:100%;border-collapse:collapse;">
	<tr class="blackbar" align="center" style="background-color:#7FB4DE;font-family:Verdana;font-weight:bold;height:20px;">
		<td>From Place</td><td>To Place</td><td>Time</td><td>Bus Type</td>

	</tr><tr style="background-color:#DEECF5;">
	</tr><tr style="background-color:#EFF5FA;">
	</tr><tr style="background-color:#DEECF5;">


Using Dynamic Property inside Html Helper with Razor fires an error



I have the following with Razor:

@Html.GoogleAjax(View.GoogleAjaxKey, new String[,] { { "jquery", "1.4.2" } })

And the I get a strange error:

  'System.Web.Mvc.HtmlHelper<object>' has no applicable method named 'GoogleAjax' but appears to have an extension method by that name. Extension methods cannot be dynamically dispatched. Consider casting the dynamic arguments or calling the extension method without the extension method syntax.

What is strange is that it works fine using:

@Html.GoogleAjax("123", new String[,] { { "jquery", "1.4.2" } })

I tried the following code line:


And the key is displayed just fine so the problem is how I use the value of @View.GoogleAjaxKey into Html.GoogleAjax.

Do I need to change something on my Html Helper? Here it is:

    public static MvcHtmlString GoogleAjax(this HtmlHelper helper, String key, String[,] libraries) {


HTML Table Disable


I have a HTML Table that I use to place the control in so they display nicely on my Web Form.  I also use the Disable method to keep unwanted users from editing those controls based on their log in information, however I still want the information to be displayed for their review.

The information is displayed for example in the Text Boxes, however when they hit Enter on the form because the table is disabled for some reason the information is lost when I do my update to the SQL Server (the text box shows "")?

Why is it I can see the information on the screen, but the text box shows empty when hitting enter on the form?



Change grid view from table to other HTML layout



You'll have to excuse my ignorance, I'm coming at this from a front-end perspective, and don't really know how to deal with data views in ASP.NET.

Basically, I'm trying to change the layout of some repeated data from a straight table, to something more design-heavy.  It's the same data, just re-organised slightly.  The current ASP.NET code looks like this:

                    <asp:GridView ID="GVMoments" runat="server" AllowPaging="True" AllowSorting="True"
                        AutoGenerateColumns="False" PageSize="20" RowHeaderColumn="FirstName"
                        SkinID="GroupSkin" DataKeyNames="moment_id" 
                        <PagerSettings Mode="NumericFirstLast" PageButtonCount="20" Position="TopAndBottom" />
                        <RowStyle />
                                <asp:BoundField DataField="moment_id" HeaderText="moment_id" ReadOnly="True" SortExpression="moment_id"
                                    Visible="False" In

Problem with Dynamic Controls



I have a custom user control that contains within it a repeater control. Inside this repeater I programmatically add another custom user control, which contains a text box and a custom validator. This final custom user control can be added any number of times depending on the application's logic. All of this is part of a wizard step.

When the user completes the step, if any of the data added to the text boxes is incorrect the validator gets fired on post back. However, because I can have any number of these controls added to the repeater, the user has to scroll down to see any of the incorrectly completed boxes.

Due to the controls being added dynamically it is not possible to use a validation summary control - I have tried!!! Therefore, is there away I can use JavaScript to position a cursor or to jump to each incorrectly completed textbox without the user needing to scroll down the page? For example, if there are 10 textboxes, and textboxes 8 and 9 have numbers inside them inside strings, then the JavaScript should jump textbox 9.

Model Binding the values in an HTML Table back to Controller / Model


Currently, I am working with ASP.NET MVC1 and am still learning about Model Binding and how values from a View are passed back to the Controller / Model. Specifically, I want take an existing Model, create a Table and populate the Rows of the Table, allow the user to edit some fields and pass it back.

In my example, I have a Class called "Ingredient" which has 4 public accessors:  Name, Barcode, Amount, and Unit

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<MvcACE.DomainModel.Entities.Ingredient>>" %>

<% using (Html.BeginForm("SubmitOrder","MyController"))
{ %>

<% if (Model != null)
foreach (var item in Model)
{ %>
<td><%= Html.Encode(item.Name)%></td>
<td><%= Html.Encode(item.Barcode)%></
