Net GRIDVIEW RowUpdating

Here Mudassar Ahmed Khan has explained with an example, how to use the RowUpdating event of ASP.Net GridView control using C# and VB.Net. In order to illustrate this concept I will make use of an ASP.Net GridView control on which I’ll perform Edit and Update operations and save the updated data with the temporary DataTable. I am using OnRowUpdating in my gridview. It's fairly straight forward but for some reason it's not updating. It's as if it's not finding the EditTemplate controls. It's a bit different of a set up, as all the controls are in a single column (maybe this is causing the problems?) and it's set up in a 'blog' format.

Hello redditors,
I am beginner searching for c sharp developer jobs. I have learnt .Net Framework, C# and asp.net.But, it difficult for me grasping CRUD operation of GRIDVIEW (edit, update, delete operations) and how even handlers generated in the scripting markup program. i am not understanding the <%eval value we provide in boilerplate code. ANd also in code behind file, we create that appropriate ROWUPDATE, ROWCANCELINGEDIT, ROWEDIT events and the object e we assign inside that.
WOULD some of redditors please explain the complete concepts please.

2016.05.26 16:36 ortund Responding to select list item selection in mvc

In asp.net you'd do this with the dropdownlist set to autopostback and then you'd have an event handler to do the work:
public void DropDownList1_SelectedIndexChanged(object sender, EventArgs e) { var SelectedItem = DropDownList1.SelectedItem; // do summing with the selection } 
Normally what I did in asp.net was to dynamically update the page based on this selection by loading data to a GridView or something and that's pretty much the functionality I want to replicate in MVC.
I have an @Html.DropDownListFor on my View and when a selection is made to it, I want to display, in a table, data related to the object selected from the DropDownList.
Typically I use ajax posts and I can do it the same way but how do I load the table with the new data exactly?
@model Ortund.Models.CreateReceiptReportViewModel ... @Html.DropDownListFor(model => model.StoreId, Model.Stores) 
Receipt # Value Date
It occurred to me while writing this that If I get the receipt data back as an array of JSON objects I can loop through appending each new one to a new row in a table summing like this:
// this function will go into the else block of the previous jquery code function appendData(data) { // data contains an array of JSON objects that we're going to read data.forEach(function (item) { $('#receipts-table tbody').append('' + item.ReceiptNumber + '' + item.Value + '' + item.Date + ''); }); } 
The key here is that however the data is retrieved, the user is not to be redirected, but instead the View should just be updated seamlessly.
Think my code here will achieve this or would there be a better way?

2014.10.03 18:46 lubasndo Looking for tutorial to make live feed / auto update website

I am hoping to be able to achieve this using SQL Table, VB.net, ASP.net, Jquery, AJAX or anything similar.
I want to have a website sort of like facebook, twitter or google news live feed. But in much simpler context. Basically on the website I just have a table/gridview. and that gridview is linked to SQL table. If I insert a new row to the table, the gridview sort of auto update itself like when a new status appear facebook.
Any tips/links?
thank you
