I m working on ASP.Net database related project. I have one form including one Button, On ButtonClick I m inserting data into database.
It is working fine but when I m refreshing the page then again it is inserting same record into database.
I dont want this, so suggest me what is the problem.
I Am working on payment gateway integration, i am storing whole information about the transaction on page load event. so when i press refresh button then Duplicate data is again inserting in database So i want to stop this.
I want to do like
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
// Here I Am Using My Function For Insert Or Update Database
}
}
We have developed the Application using Visual Studio 2008, After publish we got the issue like After Submitting the Form the user can able to Move Backward and do the Refresh. This will again triggers the Submit Post Back and the Duplicate Record Created As Well.
This is happening for all the Web Forms. How to Avoid this ? I need a Generic Solution where i can implement that logic in Base Page then the rest of the Pages this functionality will be covered by default.
Moreover, Before Refresh We should also intimate user "Do you Want to Post the Same Data Again ?", if the user clicks Yes then it can allow the same record can be posted again.
How to do this ?? But i cannot disable the Browser Features like back, forward and Others. I have found many solutions in various web sites but it is also happening for the Validation Part Also...
I have a table on my page. I need to scroll down a little to get to that table. In that table i have som data that i edit and save to database. When the save is done i need to refresh the page( Response.Redirect(Request.RawUrl )) so it loads the new data to that table. When the refresh is done the page is on top again so that i need to scroll down again to see the table. This makes it very unusable for the user.
How can i refresh the page without it going back to top again? I tryed wrapping an updatepanel around the table but it didnt

I have a gridview with delete buttons for each record (I've used AccessDataSource). I have loaded the data in and have many duplicate records.
I just want to use the delete button delete each duplicate record while remains many duplicate records. For example:
I used the following query to load in duplicate records:
SELECT * FROM TableA WHERE ([ControlA] IN (SELECT [ControlA] FROM TableA GROUP BY [ControlA] HAVING (COUNT [ControlA]) > 1)))
ID ControlA PIN# FaceValue Date
delete 76637 128232 1234 5 6/4/2006
delete 72722 128232 1234 5 6/4/2006
delete 76638 234567 2345 10 7/3/2006
delete 72723 234567 2345 10 7/3/2006
What is the query to delete single duplicate record instead of deleting all duplicate records?

View 2 RepliesI have a problem when I try to pass in paramaters for a report in my report viewer. I have set up the ObjectDataSource and set the paramaters for 3 text boxes that are on the page. The only way I have found to set the paramaters for the report is the user must fill in the paramaters and hit the refresh button on the Report Viewer toolbar ,but I would like to have the user click a asp.net button insted. Is there anyway to call the refresh method from codebehind?
View 1 Repliesi m using Parameters .AddWithValue("@ ", .text) method t insert data from textbox to my data base. i m using SQL data base. primary key is auto incremented. problem is that when i click on submit button to add the data in data base, all the code works fine, and my data get inserted in database table. but then if i click on refresh page, same data get inserted again in the table. and if i click twice or thrice on refresh button data get inserted again and again. i solved this problem by redirecting the page to same page. but then i lost my view state of data. i want to keep the view state and restrict this insertion of data on refreshin. how can i solve this problem by keeping the view state.

View 2 RepliesI want to have a web page that shows the first 10 records of data.
View 8 RepliesIn a page, there are one text box (textOrderby), one button and one gridview. (gridviewOrder)
I use dataset to bind gridview dynamically. Here is the code
dim SQL as string="select * from order where OrderBy = '" & textOrderby.text & "'"
dim ds as new dataset
ds=makedataset(SQL) // a function to make dataset
gridviewOrder.datasource=ds
gridviewOrder.databind
Every time once user input Order by data and then clicks the button, gridviewOrder will display new data.
It works fine but every time page is blinking (post back) to refresh data.
Is there any way to stop page blinking which still refresh data?
I am using an ObjectDataSource in my FormView for INSERT.
Data inserts correctly to my backend SQL table, however as i am posting back a success/fail message to the same page, i have noticed that after a successful INSERT if it hit the Refresh button the INSERT is doubled up.
How can i stop a user pressing the Refresh button and doubling the INSERT?
Is there a setting somewhere or can i stop this programmatically within my ObjectDataSource_Inserting method perhaps?
I have a gridview that has allowPaging and AllowSorting set to true. It is bound to a sqldatasource with the selectCommand firing a sql query. The sqldatasource has EnableCaching = true, and caching duration = "60". The idea is to run the paging, sorting, etc from the cache.
A separate dataUpdate event updates the data that is being loaded in the grid view, but I am not able to see the change in the gridview data till 30 seconds (caching duration) .
What is the best way to force refresh the gridview data by the dataUpdate event?
I came across this artice that tells to use CacheKeyDependency, but when I implemented it, the gridview gets refreshed at every dataUpdate event, but also the paging and sorting fires the sqldatasource Selectcommand sql query. I want this query to be fired only on dataUpdate.
i want insert,update,delete,select records from databse with out refresh page and show a loading icon while intraction completed
