Forms Data Controls :: Gridview Not Refreshing After Deleting Record?
Nov 27, 2010
I am using a Gridview inside an UpdatePanel. I am using the RowCommand method to call my code to delete the record. The gridview is bound to a <list> collection. I am unable to get the Gridview to postback / refresh after the users deletes a record; however, if I refresh the page in the browser and the page loads, it obviously is gone. I have searched quite a bit on this where others are having problems but nothing they did work for me, so I was hoping someone could review my code and let me know what I am doing wrong.
Here is my ASPX:
[Code]....
Here is my C#
[Code]....
When I step through the code, the postback happens and then my delete code is called, so once the delete code happens, the page is already finished loading, which seems to be my problem.
I have a form that when I click the delete button I want it to refresh the grid with that record removed from the grid. Does anyone know how to do this. Is this something handled in the code behind? Here is my code for the delete button on the design page:
has someone make ajax.actionlink for delete to work properly.After deleting the record successfully at the end it is not refreshing the page properly.the page refresh is my problem. i have defined the updatetarget id and returning view(model) from my controller but it is returning the master page with it.So the thing is that i am having a page with a page.I have used redirect as well which is not refreshing,
I have a gridview and a SQLDataSource control. In my gridview I have 2 commandfields "Edit" and "Delete"
The "Edit" command field works as expected. Using the "Delete" command field I get the error below.
Server Error in '/DataControls' Application.
The DELETE statement conflicted with the REFERENCE constraint "FK__titleauth__au_id__0CBAE877". The conflict occurred in database "pubs", table "dbo.titleauthor", column 'au_id'. The statement has been terminated.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: The DELETE statement conflicted with the REFERENCE constraint "FK__titleauth__au_id__0CBAE877". The conflict occurred in database "pubs", table "dbo.titleauthor", column 'au_id'. The statement has been terminated.
Using vb.net/asp.net 2005.I have an inner gridview.The outer gridview is "Authors" and in the inner gridview (GridView1 below) I have to set it up so that the user cannot delete the last book from the inner grid, if they try to delete the last book from that inner grid then I want to show the exception message below.
So I am checking the GridViewRows1.Rows.Count which works great when I have one record (one book) to start with. The problem is when I have 2 books (for example). I am writing out the test statement below and the RowCount is always 2 each time, never decremented, even after I rebind.Editing this now: i realize that my initial logic is faulty because when I rebind my inner gridview I am not specifying which inner gridview so the result is that only the last inner gridview is being re-bound, so I think that I need to get the selected inner gridview and then refresh that...
I've been googling for 2 days for the solution, but I couldn't find something useful. The problem is that I have GridView that is connected to the SQL database and that is how it is being populated. I added EDIT and DELETE buttons in the columns, but as far as I can see the event which handles them is empty.
I am having trouble changing page numbers on my gridview after deleting a record if the deletion of the record causes there to be no more records on that page. Currently I have a form below the gridview that adds a record to the datasource of the gridview.
[Code]....
Code behind stuff:
[Code]....
Now with this code above, if I insert a new record using the form below the gridview, it will reload and go to the new page if the insertion causes the record to appear on a new page, however when I delete that record, thus causing nothing to be on that page, the gridview visually just dissappears. I've got the gridview bound by a linqdatasource control, and on the page_load function I only databind if the page is not a postback.
I am working on a Webbased project, where we have a Master page with some child page. In the child page there is GridView control, Footer of this Gridview control have some TextBox control to get the input value from user and insert into database. Once the data is inserted into database. We are reloading the inserted data into the same Gridview control, But Gridview control is hot Binding/showing up the recently added record.
I debugged the code and seen the Dataset which is getting the data fron database have the updated row but after binding to Gridview control. The Gridview control not refreshing the data. This is happening while we have Master page and child page.
I am using paging to my gridview (pagesize=4) . now i am in (X) page and i want to get (X+1) page top record or (X-1)page bottom record , how i can get .
I want users to select a record in the GridView and then have that record open up in the Detailsview. How would I go about getting these two tools to communicate?
i have design a web application having suppliers table using SqlDatasource..
i have a master page in my design and other form are bound to a context menu..
Now i have displayed the records in the gridview..all i wanted is after i select a record in the gridview it will display the selected record in detailview from another aspx form..
i was able to create the link to another aspx form but the data that it display is the first data from the gridview not the data that i select.
I am using VS2005 and SQL Server 2005. The problem I am having is when I call my SQLDataSource to delete rows the delete is firing twice. The trace and debugging show the code executing once. In fact right after the delete, the table only shows one delete, but right after the command function is exited the 2nd row is deleted. Also, I have tested the stored procedure to make sure it only deletes 1 one and then resequences the records.Show below are excerpts from my .aspx and code behind files.
I have a very strange problem here I am using a GridView which shows nothing the the page loads for the first time. But when user selects something from the dropdown above, it DataBind()s against whatever is returned by the stored procedure.
If ran the code in debug mode, it showed that gvMyGrid.Datasource had data in the list returned by SP.Then I did gvMyGrid.DataBind(), it keeps the same empty view.I tried one more thing, I bound the grid when the page loads for the first time to one of the default values returned. It showed the data but when I changed the dropdown selection, it kept the same data.
I've got a GridView that's databound to a DataTable that I have stored in Session. I want to be able to add a LinkButton into this gridview so I can delete rows from the DataTable, however, I need to reference the rows in the datatable somehow.
I figured the simplest was
[Code]....
but the problem is, I need to somehow cross-reference the particular row I want deleted.
Would like to know how can I delete all the session state data (Empty Cart) and deleting a single row from the gridview while still in session state. (Remove Item).
I have a gridview that shows all data from a table. DataNames includes KeyId, which is a Primary Key.Yet when I try to delete a record, nothing happens, the page appears to performa refresh but the record is still there.Edit does not work either. I used the wizard to build all of the queries, they look okay. But I cannot figure out why they are not working.
m using gridview to display records from sql server2005. In gridview, I have a field containing checkboxes. Now what i want that the fields against which a user checked in checkboxes that will be deleted by clicking on delete button just like the emails yahoo, gmail etc How can i do so?
I have a small website with a database. Just two tables for personaldata and for files belongs to the personal data.
This files are stored on HD. My problem is to delete this file by clicking on delete button within gridview. At the moment only the record is deleting but not the file which belongs to this record.
That is my Gridview:
[Code]....
and that is my codebehind file:
[Code]....
and see the screenshot. (how it looks like)
i get allready help here to create the right codebehind file for that.
i have tried that this way:
[Code]....
But i think instead of txtFile.Text the filename of thefile should be readed out of the database on this place or Im wrong?
I am trying to update my count value in gridview once i have click on my link my count value is updated, i am already do this using javascript and also i hv do this change in database and get the proper responce of that.
But i want to do that without refreshing page or gird my count value is increase which is i had.
i wanted to refresh the gridview once user enters values and clicks update button. But its not updating. If i change my selection to pop up gridview, then it is showing the updated values. I dont know where i am doing wrong. can any one suggest changes in my code?
I'm working on a project where I have to create a page that displays the "health" of a system. I run a query and display the results in a gridview with a red or green icon next to it. This works fine when the page is first loaded. My problem is that I have a thread that runs a query every 30 minutes and rebinds the gridview but the gridview never refreshes even though the data has changed. How do I get the gridview to display the new results? The databound event never fires a second time even though I can clearly see that I have received new data. I assume I am missing something simple but I just don't know what. What am I doing wrong?
I have a gridview,sqldatasource and a link button for delete in the sample code below
When Delete is click the confirmation pops up. When I confirm yes, the rowdeleting event doesn't seem to be firing. I addeed a label to see if the event is firing. To avoid runtime errors I added a dummy but actual sql delete command. Once If I get it to work, I want call a stored procedure to delete the row.
My question is
1. Why is the gridview row deleting event not fired.
