Issues with UpdatePanel and Datagrid

Posted By:      Posted Date: September 12, 2010    Points: 0   Category :ASP.Net
I'm currently working on correcting an issue with a previous developers search page.  He was using an UpdatePanel and wihtin it he had 2 list boxes, 2 radio button groups, 3 buttons and a datagrid.The users can select different options from the 2 listboxes and 2 radio button groups for their search.  Then they enter a work and press the search button.  At this point everything is fine.Now after the user gets their results back in this case it's almost 8,000 rows.  Say now the user wants to change one of the radio button options when the user picks a different radio button selection the page freezes for what seems like a minute or so then I can get access to the search button. There is no code behind on the radio button group so it should be an instant change.  I started the web page from scratch to see if I can pin point what is causing it and it seems to be too many rows in the data grid but i'm not sure how to get around it.Any help would be greatly appreciated.  Please let me know if more detail is need.Thank you

Issues with UpdatePanel, Gridview & CheckBox



I am working on a user control that contains an updatepanel. The updatepanel contains a GridView with an ItemTemplate. The ItemTemplate contains a checkbox, which is not bound with any DB column. The grid is bound at runtime with DB.

I need to select one or more rows & click button "Add" (the button is inside update panel) so that the selected records can be processed. In the button click event, I am iterating through all records in gridview but not able to get any checked checkboxes.

Can any one please let me know if I am missing anything? How can I find the checked rows in the gridview.

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.

Use Jquery with repeater, gridview, datagrid

Before we talk about jquery inside any itemtemplate (repeater, gridview, datagrid), we need to understand the basic use of jquery functions

ListBox tricky to set in a DataGrid/GridView

Listboxes are very tricky to set selected items in grid - there is no real nice way to do it. It would have been great if Microsoft included a property that accepts an array or comma separated values - or anything! But they only allow each item in the list to be selected individually. The way to do this in a grid is a bit messy, but it is fairly simple to implement. When a row is created (as per the event), select the items of the listbox as per the datagrid source data:

How to highlight datagrid or GridView row on mouse over?

This article will show how you can Ajax with GridView to display popup messages when mouse moves over certain column. In the demo project I have added first column as an image column with a help icon in it. This kind of implements a feature that if you want more information about the row you can move mouse over this icon, a asynchronous request is sent to server for data about that row and when call returns the returned message is show as a popup message.

Multiple Column Dropdownlist for the ASP.NET DataGrid

Based on my previous control "Multiple Column DropDownList for ASP.NET", I received many emails asking for the same control to be used in the DataGrid for web applications. Here we go.. This control can be used as the regular MS DropDownList in the DataGrid and also as a regular dropdownlist. It has all the properties, like DataTextField, DataValueField, DataSource, SelectedIndex etc. The download file contains the samples both in VB.NET and C#. In this sample, I have used the Northwind database of SQL Server.

Using the WPF Toolkit DataGrid

WPF comes with a large number of built in controls, but from the beginning it has lacked something that many application developers find extremely important - a DataGrid. You can use the ListView to create something approximating a DataGrid

A datagrid control that can be personalized... anyone??


Hello all,

I need a datagrid control that has following features, besides other regular stuff like paging, sorting, filtering, etc:

The user should be able to -

1. Select columns to view

2. Select column Sequence

3. Select default sort column

4. Store the setting (as a view) and use it on next visit.

5. llow multiple such views to be stored for a user for future use.

All these settings should be saved and when the user comes back he gets the same settings.

Really appreciate your time and would love to get any ideas.

UpdatePanel is not a known element - message when upgrading to 1.0 ajax


It worked on one of my old pages.  I change the web.config, renamed all the <asp.

On some aspx page it doesn't recognize the updatepanel.  It only does on one page.  If I create a new aspx page with a different name - then it works.

Should I just create a new web project ajax - then copy all my code into there?  Or is there a way to get those old pages to recognize the new ajax controls?

GridView: Move Over DataGrid, There's a New Grid in Town!


When incorporating the ASP.NET DataGrid control into your Web apps, common operations such as paging, sorting, editing, and deleting data require more effort than you might like to expend. But all that is about to change. The GridView control--the successor to the DataGrid-- extends the DataGrid's functionality it in a number of ways. First, it fully supports data source components and can automatically handle data operations, such as paging, sorting, and editing, as long as its bound data source object supports these capabilities. In addition, the GridView control offers some functional improvements over the DataGrid. Here DataGrid expert Dino Esposito introduces the GridView and explains all its long-awaited features.
