View 2 RepliesI am using cascading dropdown list where the no of dropdowns is created dynamically on the page. The cascading drop downs are contained in a User Control. I need to call a method from the Parent page which will be executed when the values in one of the dropdowns change. The server side event is not firing as I have set AutoPostback property for the dropdownlists to be false. How can i make the Page event fired from the Selected index changed of the dropdowns keeping the autopostback property to be set as false.
View 5 RepliesI've been working on my first version of an ASP.NET app, using cascading dropdowns. I've got 2 dropdowns on a page.
However, the third major control on the page is a details view. It works fantastic, with the cascading dropdowns, to display information from the second dropdown, and allow the user to edit that data. All well and good. But now, in testing, I suddenly realized that I've got no way of displaying the details view if I want to let the user enter new data, which would show some information in the second drop down.
I need to let my user add rows dynamically to a table, and after doing some research, it seems the best way to do this is through a GridView bound to a DataTable. However, I'm really struggling adding dropdownlists to the datatable, and this showing them in the gridview.
Here's the design I want:
ddl1 | ddl2 | ddl3 | ddl4 | ddl5 | ddl6 | ddl7 | textbox
When the user opens the form, he or she will be presented with one row. ddl2 etc will be populated when ddl1 is selected etc etc. When appropriate, the textbox will be enabled allowing the user to enter a comment (this is to report errors, and since users are, at best, not to trust to write the same thing twice, I need to use ddls.
Now comes the question - how do I add a ddl to the datatable? I've tried several ways, but I cannot get them added.
provide me the cascading dropdown code upto 3 levels without using the WebService .
View 1 RepliesThis has totally spoiled my .net 4 vs2010 realease day happiness. Running Cascading dropdowns using 'webservice' asmx method. Everything worked on .3.5 and i solved the running 'code In page' method with this post. Method error 500 [URL] Thought I was sorted but seems the rules are totaly different for the 'webservice method'. For example where did ToolkitScriptManager come from Ive been using ScriptManager for years. Anyway below is the Webservice and Page code. Ive looked at and tried everything of the forum but all of it is pre .4. This is demo code, the real version has 3 dependant dropdowns and the lookups are used several times so it HAS to be a webservice. My current theroies are:
1. Permissions- dosent makes sense.
2. Something missing in web.config to enable webservices.
3. Something to do with placement of 'System.Web.Script.Services.ScriptService()>'

Using ASP.NET 2.0
I have a gridview populated by a SQLDataSource that is fairly complicated on a dataset changing constantly. It takes a second or so to fetch the data.
I want to have external dropdownlists for filtering the data that appears in the gridview, either with a FilterExpression or with parameters.
The problem is that querying the database to populate the dropdownlists takes a long time, because of the complexity of the query. The values in the dropdowns can vary based on other filters.
Is there some simple way of querying the database only once, for the main gridview, and then somehow querying the local (to ASP.NET) copy of the data to extract distinct values for populating the filtering dropdowns? I am thinking this might speed things up a bit.
Here I am binding a gridview. I dont know exactly how many rows it will exists. there may be from 1 to n rows possible there are 4 columns.
Now what I want , i.e. after gridciew binds records, suppose there are 4 rows are bounded to gridview, I want to send all rows data through mail, but in my html format there are fixed rows. I want to add rows according to throws which gridview having.
suppose gridview binds 3 rows the mail format should be like this
Date From Date To Place Days
12/12/2010 14/12/2010 Mumbai 2
12/12/2010 16/12/2010 Goa 4
12/12/2010 20/12/2010 Pune 8
1. first tell me how to get this data from gridview in variables so that i can put them in my mail format
2. this condition if grid bind only three records cos I have fiexd rows in my html format.. but if grid is haing 5 records then how will I add rows to table in my mail html format
I have 3 dropdowns in my VB.Net 3.5 web app. After a user selects a value from the first (let's call it Countries) the second (called States) should populate correspondingly. Dropdown three (cities) should also cascade down after a State is selected. The Countries and States dropdowns have SQL DataSources. The Cities dropdown has to call 2 procs (based on the selected State value) so it does not have a SQLDataSource. My question is, the code below works for Countries and States, however, I cannot ge the Cities to populate...
<asp:DropDownList ID="drpCountries" runat="server" DataTextField="CountryName" DataValueField="CountryId" DataSourceID="sdsCountries" AutoPostBack="true">
</asp:DropDownList>
<asp:SqlDataSource ID="sdsCountries" runat="server" ConnectionString="<%$ ConnectionStrings:MyConnectionString %>"
SelectCommand="SELECT * FROM [Countries] ORDER BY [CountryName] ASC"></asp:SqlDataSource>
<asp:UpdatePanel ID="updStates" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:DropDownList ID="drpStates" runat="server" DataTextField="StateName" DataValueField="StateId" AutoPostBack="true" DataSourceID="sdsStates">
</asp:DropDownList>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="drpCountries" EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>
<asp:SqlDataSource ID="sdsStates" runat="server" ConnectionString="<%$ ConnectionStrings:MyConnectionString %>"
SelectCommand="SELECT * FROM [states] WHERE StateId = @StateID ORDER BY [StateName] ASC">
<SelectParameters>
<asp:ControlParameter ControlID="drpCountries" Name="StateID" PropertyName="SelectedValue" DefaultValue="" />
</SelectParameters>
</asp:SqlDataSource>
THIS DOES NOT WORK:
<asp:UpdatePanel ID="updCities" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:DropDownList ID="drpCities" runat="server" DataTextField="CityName" DataValueField="CityId" AutoPostBack="true">
</asp:DropDownList>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="drpStates" EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>

' Call some procs and get a DataSet
drpCities.DataSource = ds
drpCities.DataBind()
End Sub
I am adding table rows dynamically, after I return from a post back, these rows disappear.
Is there a way to preserve these rows and add them back on page load?
How to create a table in the code behind to display data from the database by creating a new table etc. How I could target existing HTML in my aspx file as opposed to creating a new table in the code behind?
View 1 RepliesI have three cascading dropdowns and two of them need to trigger something outside of the dropdowns, so I have OnSelectedIndexChanged events on them. So as to not reload the whole page when these items are triggered, I have all of this in an Update Panel.
Everything works fine -- the only issue that the client doesn't like is that the cascading dropdowns reload on the asynchronous postback.
I have a grid with 3 templetefield columns. Above that i have a checkbox list collection. i want to add no of rows equal to no of checkbox checked from list.
If I check 3 checkbox then 3 rows should be added to grid dynamically without postback.. I am trying to do it using javascript.
I have a working version of cascading dropdowns.

I have three cascading dropdowns on my web page and they work fine. The issue I am facing is that there are other controls on the page which cause a postback and with each postback the cascading drop downs are being re-populated (service methods are called) which is becoming a performnace issue.
View 1 RepliesI am trying to delete or add rows in a table but since the table is in an update panel,upon deletion the row goes away and then comes back.I have tried using return false but it does not seem to work in IE or FF.
I am using the following code:
$(document).ready(function () {
$(.table).click (function ()}
(this).parent().remove();
[code]...
Basically I need a way to disable the postback.
I am using Asp.Net 3.5 along with C# and database is SQL Server 05. I am using Asp.net menustrip that is bind with with data source using LINQ to SQL. i also add some CSS stuff with menu so that after applying CSS my menu show at top of website horizontally.
But i need some JQuery Menu (stylish menu) which should be populate dynamically.
For Example i created two roles 1) Admin 2) User
When admin loggin the admin menu show when user loggin admin menu hide and all the data of menu is populate via JSON file. I am using sitemap to populate menu but now i want some JQuery Menu which is stylish and should populate accodrding to needs not be hard coded.
I've created a static table, which looks just as I would expect it to, but I want to reduce my work in the future, as I'll need to create more rows and columns to store extra data that's added to my application.
So rather than creating new rows and columns whenever I need to, I'd like to automate the task by pulling the data from the database and populating a table that's dynamically created based on how much data is pulled.
e.g. if there are 10 rows of items in the database, create 10 columns and 10 rows, if a further 5 things get added next week, I want to add another 5 rows and 5 columns etc
Is this where "Dynamic Data" would play a role? If so, it's completely new to me, my needs are just for a single table on a page, not something that needs to be done en'masse all over the website, if that makes a difference?
Am using masterpages.I have written following code to add rows to dynamictable with html controls.
I need to load data from database in cascading dropdownlists(like country,state);this javascript code is not accepting asp controls.can we load data in cascading html dropdowns? using javascript/AJAX?
html:
<input type="button" value="Add Row" onclick="addRow('dataTable')" /> [code]....
So today I started learning ASP.NET. Unfortunately I haven't found any good tutorials online, and I can't afford to buy books at the moment, so I've had to create a ASP.NET web application in Visual Studio 2010 and just play around with the default project setup. So far here's what I have in my Default.aspx:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

</head>
<body>
<div style="padding-bottom:10px;"> Project Management System</div>
<div> <table style="width:100%;">
<tr>
<td>Name</td>
<td>Task</td>
<td>Hours</td>
</tr>
</table></div>
</body>
</html>
I created a simple table with the header row already in there. Through a C# script, I want to be able to dynamically add rows to this HTML table. Is this the right way of thinking in ASP.NET? If so, how can I do this? I'm sure I'll need an "Add" button, which adds a new row to the table, with editable fields, and a "submit" button which adds some stuff to a database. Basically just a rundown of how this is done would be ever so helpful. Also if anyone knows any good tutorials or websites
Does anyone know how to dynamically add and remove rows in a table triggered by a button click from the backend (in c#) using asp.net?
Here's how it might be done in javascript, is there any way to do this in the asp.net framework?
[URL]
Protected Sub btnAddRow7_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnAddRow7.Click
Dim tableRow As New System.Web.UI.WebControls.TableRow
Dim tableCell As New System.Web.UI.WebControls.TableCell
Dim textBox As New System.Web.UI.WebControls.TextBox
tableCell.Controls.Add(textBox)
tableRow.Cells.Add(tableCell)
tbl7.Rows.Add(tableRow)
End Sub
but it only adds one row dynamically. After the first addition, more clicks to the button will not add more rows.
is there any easy way to add city names,state names,and country names in dropdownlist..
