Remove a dynamically added ListViewItem from a ListView

Good day, In my xaml I have created a window in my app which contains a  ListView control. I have programmatically added ListViewItems. The ListViewItems each contain a grid. Grid column 0 contains a textblock, Grid column 1 contains a textbox and Grid column 2 contains a button. What I would like to do is click the button in the ListViewItems grid, and remove the ListViewItem in the button is contained from the ListView. Could anyone suggest a way to do this? I would really appreciate any advice, as this is crucial to the feature I am creating.

dynamically adding sql server columns based on number of files in fileuploader


I want to create a new table to sql database at runtime.  The column names would be "Name", "Date", "Event".  I would also like to have one more column name "Image" but the problem is that since the amount of images will vary, I want the application to count the amount of files in the Multiple fileuploader and then add a image column to the table for the respected amount of files. 

For example if i am uploading 3 files in the multiple fileuploader, the names should be "Name", "Date", "Event", "Image1", "image2", Image3"

I also would like that table name to be name dynamically from the textbox Name when the user enters the information.


I have the following code to make a new table, but I dont know how to name the fields at runtime like previously asked please help!!!

using the linqDataSource control programmatically (dynamically)



my scenario is this: I want to use the linqDataSource control to bind data to a gridview for it's efficient built-in paging and sorting features *but* I don't want the data to be bound until the user has input various search parameters, so I need to bind the data from a button click event. Also, the search options will be somewhat complex in that there will be several optional search parameters, via various dropdowns and textboxes, so I can't just declaratively/statically setup all the WHERE parameters on the linqDataSource (at least I'm assuming I can't, or that it may result in poor performance if I do and just assign default values like the everything wildcard '%' for the cases the user doesn't use a particular search parameter). Given that brief description, here is an example of what I'm doing, but with only one WHERE parameter for simplicity, the real code will be adding anywhere from 1 to about 12 WHERE parameters depending on how the user sets the search options in the GUI.

<asp:LinqDataSource ID="ldsMain" runat="server" 
        Select="new (field1, field2, field3, etc..)" 

Search for a string in my datasource dynamically


I am displaying an Rssfeed on my page by using XmlDataSource and Datalist controls.

I want the user to be able to limit the information that is returned to my datalist.  To do this I have a textbox on the form that allows the user to enter their search criteria.

I need to be able to dynamically create a query string utilizing the information that the user entered in the textbox.  I am also using a drop down list and allowing the user to select whether they want to search in the title, description, or all parts of the xml file.

I am having trouble figuring out how to reference the data contained in my textbox in my query string.  Where the query string says 'asp', I want to replace 'asp' with the content from my sSearch variable.  Can anyone tell me how to reference my variable in the query string???

string sSearch = txtSearch.Text;
        string SQuery = "";

        if (DropDownList2.SelectedIndex == 0)
            SQuery = "[contains(title), 'asp')]";

Web deployment project - web.config section replacement does not add remove tag


I have a web application that is actually installed as a component of a third party site.  In some configurations, I need to remove certain connection strings and re-add them.  I'm replacing this web.config section with a xml file that includes the following:

      <remove name="MyOverridenConnection"/>
      <add connectionString="Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=MyDb;Data Source=MyServer" name="MyOverridenConnection"

For some reason the remove tag is left out during the substitution and I end up with the following in the installed config:

      <add connectionString="Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=MyDb;Data Source=MyServer" name="MyOverridenConnection"

I need to develop 3 pages.

On the first page user defines atmost 7 column names to be displayed on the report. I'm saving these names in a Sql DB table 'Columns' with Column_Nm and Column_ID as Table columns.

On the second page I'm retrieving column_Nm from the table and displaying them on the page so that the user enters the data. This data is saved in another table 'Summary' with the Columns column1 through column7.

.NET Reflection: Dynamically Bind Your Data Layer to Stored Procedures and SQL Commands Using .NET M


One major inconvenience of using SQL stored procedures from code is having to match type information. You have to write long wrapper functions around the procedures just to expose the data types. In the .NET Framework, however, the reflection services of the System.Reflection namespace allow you to query rich metadata that describe data types. This article explains how to use reflection in .NET to end your stored procedure nightmares. The author creates four custom classes, including one that generates a SQLCommand object based on the metadata of a method. Using this library, you'll be on your way to automating the generation of stored procedures.

Dynamically load user control without postback


Hi all,

I need urgent help. (c#coding)

In my base page, I have a dropdownlist control which loads different usercontrols on selectedindexchanged event.

While loading these usercontrols, my page postbacks all the page. I used updatepanel but again same problem.

Is there any way to load controls without postback? I Really need help as soon as possible.

Here is my code:

protected void Page_Init(object sender, EventArgs e)
        if (Session["control"] != null)
            string c = Session["control"].ToString();
            if (c == "1")
                iuc = (IlkogretimUC)LoadControl("~/Controls/Ilkogretim.ascx");
                dl.SelectedValue = Session["control"].ToString();
            else if (c == "2")
                luc = (LiseUC)LoadControl("~/Controls/LiseUC.ascx");
                dl.SelectedValue = Session["control"].ToString();
            else if (c == "3")
                youc = (YuksekokulUC)LoadControl("~/Controls/Yuksekokul.ascx");

dynamically change html code when user is authenticated


So I have a fairly simple web site which allows an Administrator to edit some data in a database which is displayed on some web pages.

The main navigation on the site is shown in the code snippet below. The Admin link goes to a Login.aspx which allows the Administrator to log in - once authenticated they get sent to the data edit page.

So my question is, how could I dynamically add a link to the data edit page in the <ul> list below once the user is authenticated ?

This would allow the authenticated user to see links to the secure pages in the main navigation bar.

<%--Top Navigation Menu --%>
<div id="topMenu">
<li><a href="default.aspx">Home</a></li>
<li><a href="introduction.aspx">Introduction</a></li>
<li><a href="curriculum.aspx">Curriculum</a></li>
<li><a href="times.aspx">Times & Fees</a></li>
<li><a href="staff.aspx">Staff</a></li>
<li><a href="login.aspx">Admin</a></li>
</div><%--End of topMenu Container--%>
<div id="clear"></div><%--Floats items cleared End of Master Page--%>
