So, I have a button inside a listview:
[Code]....
with a commandName="confirm" and its CommandArgument the memberid from objectdatasource. I have create a code behind to put certain action to the said button..
[Code]....
But it has no effect. Did I make some mistake? I'm still new in this ASP.Net things.
I am trying to populate the ListView using LinqDataSource data source but the issue I am having is.I need to load the listview on Search button click action.
IN the page_load I kept like this:
===========================================
LinqDS.Selecting += new EventHandler<LinqDataSourceSelectEventArgs>(LinqDS_Selecting);
protected void LinqDS_Selecting(object sender, LinqDataSourceSelectEventArgs e)
{
e.Result = ObjectDS;
}
=============================================
This works fine but this happens on page load,i want this binding to happen on button click?is there a way to do this?
I've a listview in which i'm binding data from objectdata source. I have a requirement where i've to allow edit/delete for only certail listviewitem which meets specific requirement. How do i dynamically set that some item can be only be edited not deleted thus only edit button/link should appear and vice-versa.
View 2 RepliesI am using a LINQ to SQL data source for a ListView and perform a validation check in the Listview ItemUpdating event:
[Code]....
This works great and keeps the user from updating the record with invalid data.However, when I hit cancel after this operation, it saves the text in the box rather than cancelling the operation. Here's my code for the update button:
[Code]....
Update Function:
[Code]....
I do not handle the cancel button event, as the cancel operation has worked fine... unless someone enters incorrect information and e.Cancel is set to true.What am I doing wrong? Is it the mixture of using the LINQ Datasource and doing my own updating?
in the nested ListView (or the child ListView), the edit command does not work.
It seems that the <EditItemTemplate> is not properly excecuted by the edit button in the <ItemTemplate>.
Interestingly, the edit command in the parent ListView works well.
The insert and delete commands in the nested ListView also run without any problem.
But I get no change by pushing the edit button which is located for each reply (the item of the nested listview)
Here is my code.

Within my ItemTemplate on a listview i have a link button carrying out a delete command. As it's a custom command i use the ItemCommand to do the deleting and have a stub itemdeleting.
It works fine set out like this however i only want the delete button to be available to logged in users. If i wrap the linkbutton in a loginview and then click on it the ItemCommand and ItemDeleting never get called the page just refreshes.
I would like to know if I can do the following: when I am in insert mode, can I dynamically change the select command of and then display that result in the second dropdownlist based on what was selected in the first dropdownlist.
I would like to include the minimum code to demonstrate what I am trying to do.

I have a simple table, ID,Fruit,StockSo, the rows are its primary key (ID), Fruit type (Orange, Apple etc) and Stock (1 is it is in stock, 0 if it is out of stock).I have a grid view on a page which lists the rows.What I would like is a button that executes a SQL command based on the row.(The command is just an update to change the Stock field from 1 to 0).The query i tried was UPDATE [Table] SET [Stock] = 0 WHERE id = @id

I'm trying to create a ShoutBox for my site, and for those of you who are not familiar with shoutboxes, they are chat boxes on websites that users can post live messages on, and the other uses will see their message and be able to respond. I didn't find any good ones online, so I started to write my own. I'm doing it with an XML, but I want the user to be able to post messages using a textbox I added (txtMessage) and the button (cmdPostMessage), which should add a new item to the XML file, and all the other uses will receive that message (their xmlDataSource and the DataList will PostBack every second or something like that). It is able to read messages, but not send.I am however facing three problems:
1- I need to find a way for the user's input to be added to the XML.
2- I need to find a way for the current logged-in username to be found, and added to the XML, and also detect if no user is logged in, in which case the user wil receive an alert saying "Please log in to post messages to the ShoutBox" and redirect them to the login page.
Here is the text in the XML

I want to know how we can get the command argument of a Image button in Javascript.
Scenario:
I have a grid in that I have image button in template column.on click of each image button i have to redirect to another page with respective ID fields.
I would like to add a command button at runtime. Can someone show me how or point me in the direction. I googled it without success.My design code and code behind is below.
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<div style="position:absolute;top: 100px;left: 150px">

I have 3 gridviews in one of my web page, each of which will display different data based on the typeid. I have simplified the system structure in the image below(further description will be stated below the image):
As shown in the image above, the web site(presentation layer) will work closely with the Business Logic layer(BLL) and Data Access Layer(DLL). ObjectDataSource control will be the middle man to select, update, insert and delete the data in the gridviews.
During Select, returned data from the database at DAL will be stored in a datatable and return to BLL and then the website itself.
[code]....
However, the Update(command button) and Delete(template field) doesn't work,the RowUpdating and RowDeleting event wasn't trigger when I click on the button, but it works if I set the gridviews' datasourceid to the objectdatasource.

I have to link any selected record from my gridview to a new pop up form i.e pass the query string to a new form, using a command button. The new button will allow the user to add new information about the particular record and save it. A detailsview form would not work as the information that needs to be added is quite complex. I am using VB.
