Sample Project For Select, Edit, Delete And Insert In New Page?
Jan 29, 2010
Lot of times I did edit, delete, insert in my webproject in different pages but I am very surprised that why I am not remembering the technique to do these task. Actualy I never take any course on asp.net/vb.net, what I did in my project just to take help from forum or asp.net website etc. I get a task again to make a web interface having functionality to view data and provide Edit functionality also. The other task is to click a link in the same page to open a new page with the fields of the same table to insert new record.
Q1: Is it necessary to take a dataset or I simply do it using sqlDatasource?
Q2: Could anyone give me a very basic and simple vb.net/asp.net project with all above tasks so that I will do a practice project and never miss it?

I was trying to do it with Gridview and Formsview.
How to insert images into database and how to retrive and bind images to gridview using ASP.NET . After displaying gridview data i want to edit data with Image also using ASP.NET with Database.

Edit and Delete functionality works flawlessly in Gridview if all data is pulled ONLY FROM ONE TABLE. But pulling data from one table give you ID's instead of actual values that are stored in other tables.
After creating a usable Select statement that would pull all the correct values, my Edit and Delete functionality no longer work.
I can open the modalpopup, can close the popup, but if i click the "edit" button to edit any of rows, the popup closes automatically. If I click again, the "Update" and "Cancel" buttons shows, and after clicking one of those, popup closes again. The above code works, if i use gridview the insert, edit or delete the data, does not close automatically. What may be the cause of this problem.
I'm using a listview control to do a survey stuff. Everything is working perfect to present the data questions, to be answered text with the different type of controls radiobuttonlists, checkboxlists, dropdownlists, etc. The admin can modify, create, change questions, answers, etc. on the survey.When it's select, edit, or insert it's easy to find the control inside a listview.However, I'm wondering how to post user's answers back to DB. How to find controls inside the listview to grab the entered data/responses from there using let's say the submit button that is outside of the listview.I believe there should be a way to do it as otherwise why we put radiobuttonlist on a listview that somebody could click it and then we should be able to get that entries. Or I'm too optimistic on this control?
I am still at the elementary stages of Linq To Sql and Entities usage. I started practicing MVC developement by following the NerdDinner tutorial here at asp.net, and I back myself up with fully developed NerdDinner sample (1.0 -- still on VS2008). I am also at the first half of the NerdDinner tutorial (I think -- maybe I'm further along) - so far I have gotten up to the Delete View. In the fully developed sample I noted that it uses ascx file (which I guess I will find out if the tutorial also will use ascx files down the road). My sample app, which I am developing from the tutorial, seems to work OK so far. My issue is that I am not clear how the Delete mechanism works. In the DinnerRepository.cs I have this code (from the tutorial):
[code]....
It looks like a dinner object is being passed to these mechanisms and the delete occurs based on a row ID value. But what if I wanted to delete multiple rows - say where ID between 15 and 20 - how to go about this? I was looking for a Delete statement but am not finding it either in what I have developed so far from my tutorial sample or from the fully developed sample. How can I control Deletes in MVC?
i ma new to asp.net, i am just learning asp.net using this site and some resources from internet , internet is the only source for me. and here i have a project that should be designed by the patter of 3 tier architecture. i have an idea, but i couldn't start it, need your guidance, if i did this , it will very useful for me to get a job.these are the requirements and steps.
How do I reference the delete button to add the delete confirmation box when I have both the Edit and Delete buttons as the last two columns in the Gridview control. The following code works fine without any issues when I have the delete button only:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType != DataControlRowType.DataRow) return; int lastCellIndex = e.Row.Cells.Count - 1; Button db = (Button)e.Row.Cells[lastCellIndex].Controls[0]; db.OnClientClick = "if (!window.confirm('Are you sure you want to delete this record?')) return false;"; }
But, when I have both the Edit and the Delete buttons, I get the following error when I click the edit button while the delete button works fine.
Specified argument was out of the range of valid values. Parameter name: index
How do I reference the delete button so the edit button is not affected in this case?
im not sure why but my gridview seems to have stopped working in all areas of Editing, Deleting, Sortinging and i cant click the page number to switch between pages.Ive looked up numerous tutorials and on forums and still cant seem to find a solution that works for me. I have the edit delete sorting and paging check boxes selected.
When i click on any of the links nothing happens. not even a refresh.
