Format Width Of AutocompleteExtender AjaxControlToolkit

By default, the width of the autocomplete list of autocomplete extender is inherited from the target control which is the textbox. However, you can customize the width and appearance of the ajax control: 1. Create an asp.net website 2. Add a webservice to your site 3. In your webservice, add a code to retrieve customer or any info. 4. In your asp.net website, add an aspx markup similar below:  Note that CompletionListElementID target control is the div called autocomplete declared below the textbox. <asp:ToolkitScriptManager ID= "ToolkitScriptManager1" runat= "server" > <Services> <asp:ServiceReference Path= "~/YourSampleService.asmx" /> </Services> </asp:ToolkitScriptManager> <div> <table> <tr> <td><asp:TextBox ID= "txtName" runat= "server" ></asp:TextBox></td> <td><div id= "AutoComplete" runat= "server&q

Simple WPF Datagrid Demo Or Tutorial

I have developed a project on WPF before. WPF has been utilized in Vista OS and other software. But this cannot replace the stability of Windows Forms. Still, I don't have ample time to dive deeply in WPF, hopefully soon! LOL.. :D So, to begin with: 1. Download and install WPF Toolkit (Visual Studio 2008) 2. Open Visual Studio 2008 3. Add a WPF Project (Just call it GridDemo) 4. Add a DataGrid in your Window.xaml 5. Make sure to have referenced wpf toolkit: http://schemas.microsoft.com/wpf/2008/toolkit/ 6. Customize Your Grid <grid:DataGrid AutoGenerateColumns= "False" Margin= "8,11,10,78" ItemsSource= "{Binding}" Name= "CusGrid" > <grid:DataGrid.Columns> <grid:DataGridTextColumn Binding= "{Binding Path=CustomerID}" Header= "Customer ID" /> </grid:DataGrid.Columns> ....other columns goes here </grid:DataGrid> 7. In your Window1.cs file, populate your gr

Using JQuery Intellisense In An External JavaScript File Of ASP.NET Web Forms

Code In Gridview RowDatabound Not Working If Rowstate Is Alternate|Edit In ASP.NET Web Forms

In a gridview rowdatabound event I have this condition to check if rowstate is in edit mode: if (e.Row.RowState == DataControlRowState.Edit) //row is in edit mode { TextBox actdaterec = (TextBox)e.Row.Cells[1].FindControl( "txtDateRec" ); actdaterec.Text = string .Empty; TextBox cashRec = (TextBox)e.Row.Cells[2].FindControl( "txtCashReceived" ); cashRec.Text = string .Empty; } The code above usually works if the rowstate is in edit mode, however on the succeeding rows the rowstate becomes Alternate|Edit . The code above does not work. So the solution would involve C# bitwise operator (&) . See the revised code below: if ((e.Row.RowState & DataControlRowState.Edit) > 0) //row is in edit mode { TextBox actdaterec = (TextBox)e.Row.Cells[1].FindControl( "txtDateRec" ); actdaterec.Text = string .Empty; TextBox cashRec = (TextBox)e.Row.Cells[2].FindControl( "txtCashReceived"

Validation In ASP.NET WebForm Not Working For Confirm Dialog

In this scenario, I have a series of textbox controls that has required field validations and a save button with the following attribute property set in pageload event: btnSave.Attributes.Add( "onclick" , "return confirm ('Proceed saving or updating this record?')" ); In most cases, this works fine, but the problem is if i clicked ok in the confirm dialog of javascript, the validation of required fields will be bypassed. So the solution would be to modify the script to return false if cancel is pressed in the confirm dialog of javascript so that validation will work.Here is the modified script: btnSave.Attributes.Add( "onclick" , "if(!confirm ('Proceed saving or updating this record?')) return false;" ); If the user will click ok, in the javascript confirm dialog, validations will be executed.

jQuery In ASP.NET Web Forms Ajax Does Not Work After Partial Postback

I encountered a problem with jquery in asp.net ajax with master page content. During first pageload, the jquery script works fine, but after partial postback, the jquery script does not work. After a few googling activity, I came upon this site: http://encosia.com/2009/03/25/document-ready-and-pageload-are-not-the-same/ This explains how to use document.ready, pageload, and Application.init. In my previous code, i've used document.ready since my aspx page was not ajax enabled. But since, Im switching my application to ajax ready, the solution I came upon was using function pageLoad() instead of document.ready(). Example: 1 2 3 4 5 6 7 function Pageload() { $( "#txtsomething" ).blur( function () { //your js code here var x = 25 + 25 ; alert(x); }); } Hope this insight will help other developers out there... Here is the summary from the direct link: $(document).ready() Ideal for onetime initialization. Optimization black magic; may

Formatting Numbers With Comma Using Regular Expression In JavaScript

In asp.net c#, this can be achieved by String.Format(), however in javascript/jquery, this can be achieved using a simple JavaScript function: 1 2 3 4 5 6 7 8 9 10 11 function addCommas(nStr) { nStr += '' ; x = nStr.split( '.' ); x1 = x[ 0 ]; x2 = x.length > 1 ? '.' + x[ 1 ] : '' ; var rgx = /(\d+)(\d{3})/ ; while (rgx.test(x1)) { x1 = x1.replace(rgx, '$1' + ',' + '$2' ); } return x1 + x2; } In your script, you can call it using: 1 2 3 var number = 123456.99 ; var result = addCommas(number); alert(result); Source: JavaScript Number Format

The default color is: #7F9DB9 (Firefox/chrome/IE) #DADADA (Safari) CSS Code: 1 2 3 4 .Disabled { border-color : #7F9DB9 ; } Or you may use the border attribute and define other properties such as border-style, border-width and border-color.
