Update panal and triggers outside

Posted By:      Posted Date: September 27, 2010    Points: 0   Category :ASP.Net

I have a few buttons on a web page.

I have an update panel and I have 2 triggers that reference button 1 and 2 outside my update panel.

When I click on button 1  and 2 I want the update panel to "update" with content without a whole page refresh.

This seems simple enough but when I run I get the following error:

A control with ID 'btn1' could not be found for the trigger in UpdatePanel 'updateSomething'.

Here is my code.

<asp:button ID="btn1" Text="press me" Click="btn1_Click></asp:button>

<asp:button ID="btn2" Text="press me2" Click="btn2_Click></asp:button>

<asp:UpdatePanel ID="updateSomething" UpdateMode="Condtional" runat="server">
                    <asp:AsyncPostBackTrigger ControlID="btn1" runat="server"  EventName="Click" />

Update Panels, Postback Triggers, and GridViews, Oh my

I've been battling with this page for the past couple days and it works, but it's annoying, so I am hoping someone maybe has dealt with this and can help me a little.   I have an UpdatePanel that acts as a container for a number of other update panels, everything in this container works.  I got the bright idea to add a ModalPopup Extender to enhance the user experience a little when performing a certain function on the site.  The panel that acts as the container for the ModalPopup sits outside the UpdatePanel Container because if it's in the container, any interaction with a child control throws "Input string not in the correct format" error message.  Because this is outside the comfort of the UpdatePanel Container, any control that populates information into the Popup control has to register a Postback.  Thus my problem: the controls that populate the Popup are GridViews.  The only GridView Event I care to cause a PostBack is the SelectedIndexChanged, but PostBack Triggers don't care, they take all comers.  Want to go to the next page? PostBack. Sort? Hell Yeah, Postback. My initial solution is to provide a confirm type of a message under the gridview and have the user confirm their selection by clicking a button to avoid causing a postback until it's necessary, but you know what? That kinda sucks, so I sub

using triggers to keep all versions of rows after update, delete + replication

I maintain an application that uses SQL 2005 / 2008 for data persistence.
Some clients use Merge Replication (pull or push) to replicate data.

Some of the tables contain information that should never be erased.
All versions of a row from such a table should be stored, somewhere in a database.

This means all updates and deletes to those rows should result in in 2 affected rows:
• a copy of the row before the change
• a row containing the change (or the deletion of the row in question)

I plan to achieve this using AFTER UPDATE,DELETE triggers on all the tables for which "versioning" is required.
The old versions of a row may be stored in the same database, an other database (or a database on a linked server).

I was hoping to do this by creating NOT FOR REPLICATION triggers on the published database.
The theory was:
All update and delete queries performed against a subscribed database should be replicated (for concurrency) to the publisher.
When the updates and deletes are replicated, the triggers on the published database will be fired, thus also updating the table containing the version rows.

There seem to be 2 problems with this approach:
An update query against a table of the subscriber wil often result in mupltiple update queries performed ag

ASP.Net Gridview Edit Update Cancel Commands

In ASP.Net 2.0, GridView Control also provides the functionality to edit and update the data retrieved from the database using CommandField template. You can cancel the action using Cancel Command of the CommandField. GridView consists of events that can be used to perform the actions like edit, update and cancel upon the Data items displayed in the ASP.Net GridView Data Control.

How to format and update GridView and DataGrid rows using JQuery

The behavior described in this question is as expected. When you set text of a cell in grid, it directly affects HTML that is going to be rendered. When you set text value of a cell, it means that you are setting innerText of the cell. The column that GridView creates for command fields (Edit, Delete and Select) are a (anchor) or button elements. So you can see what will happen if you set text value in that cell. It will wipe out those link or button controls and replace them with simple text string.

Update Vs SystemUpdate

Many of you might noticed that share point ListItem has Update() method as well as SystemUpdate().

What is the difference between these two methods and why MOSS has two different APIs for updating an ListItem

SqlCommand.ExecuteNonQuery() returns -1 when doing Insert / Update / Delete

Sometimes you end up with a return value of -1 when using the SqlClient.SqlCommand.ExecuteNonQuery method.

Why is that?

Well, the ExecuteNonQuery method is there for statements for changing data, ie. DELETE / UPDATE /INSERT, and the returned value are the number of rows affected by that statement.

When checking the documentation we can see that there are some conditions that return -1.

For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command.

When a trigger exists on a table being inserted or updated, the return value includes the number of rows affected by both the insert or update operation and the number of

rows affected by the trigger or triggers. For all other types of statements, the return value is -1. If a rollback occurs, the return value is also -1.

>>>How to update multiple rows of gidview by one click



I want to add multiple rows of a gridview if the data for multiple fields are same.

Idea for this is that a user may search a record with some parameter e.g. Sector, plot.

For example 15 records being displayed in gridview.

There should be checkbox before every row and if user wants to update Plot and Flat No that is same for 10 rows out of 15 so he will check the rows and update.

For this a dialog box should appear asking for the parameter i.e. Plot and Flat or something else next time may be it will be City or country. Moreover, there is already an Edit button to update records, when user click it another page open for the record to be updated and whatever he wants to update, it updates.

Hope everone understand the scenario.

I don't want to disturb the already provided Edit functionality and want to provide same record to be updated.

Any idea in this regard would be appreciated.

Visual Studio closes itself by opening aspx-Page designer after Windows Update


Hey Guys,

I've a problem with my Visual Studio.

On the 13th of August 2010 i installed a Windows update on my vista sp2 pc. For this date my Visual Studio 2008 sp 1 always has closed itself by opening an aspx-page in designer view. There is no error message just closing the window. I restored a backup of my windows from the time before updating it and it helped, i could open aspx pages in the design view till the update has been installed again automatically after rebooting the pc. I can't disable windows updates, cause it's my pc at work and safety is very important. I hope you could help me out of this disaster.
