Vb.net - GridView Doesn't Refresh?
Sep 17, 2010
I am relativity new to asp.net programming, so this one has me stumped. I manually created a dataset and set its value to the Datasource of the GridView control and then call the Databind method, but it isn't refreshing. I recreated a simple version of what I am doing so someone can advise me what I am doing wrong. I didn't include the Master file, as I didn't see it as pertainent.
Code for ASP page
<%@ Page Language="vb" MasterPageFile="~/MasterPage.master" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="TestGridView._Default" %>
<p>
<asp:GridView ID="GV1" runat="server" AutoGenerateColumns="false">
<Columns>
[Code]....

I have a Shopping Cart Summary User Control that doesn't update without a full browser refresh.
The scenario is:
I have a DataList in one User Control that displays Product data with an ItemCommand event for an 'Add To Cart' button.
[Code]....
When the 'Add to Cart' button is clicked, the page reloads and another User Control containing the Shopping Cart Summary should be updating. However, the Cart summary doesn't fully update until a full page refresh occurs.
I should add, that the Cart Summary is "located" on a master page whereas the Product List is in the Content Placeholder of a web form based on the same master page.
I can provide more of my code if required but I'm initially reluctant incase I'm making a noobish error!

I am using System.Web.Caching.Cache in an assembly used by my website.
I have set some key expiration (absolute expiration) to be 10 seconds (just for debugging).
I have also set a callback upon key removal.
The problem is that I see that the cache is getting refreshed after something like 20 seconds and not 10.
I am using HttpRuntime.Cache for this.
I would like to show a code sample, which can shed more light:

What could be the problem ?

I have many controls like dropdown, radiobuttonlist, etc on my page and I put all these controls inside the update panel so that the page doesn't look to be posting back when something is selected. Now the working on the page is very smooth. But the session object isn't getting refreshed even if I postback to the server and as a result even if the users are working on the page they are being sent to the login screen after 20 mins.
Is there anyway where I could put all the controls in update panel and still refresh the session after any postback(dropdown selection)

I 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?

have a Gridview which repopulates itself when I click on a button outside the grid.This works fine, except that when I click on a button on the grid after repopulation, it gives the old values rather than the updated ones. I notice that querying GridView1 gives the grid when it was first populated.Anywhere I could have gone wrong?is already true.

I've been working on a colleagues site, and have been unable to fix a coupld of issues with it. One of which is a refresh of a Gridview panel.
The page allows a user to navigate a tree structure and then display the permissions on a user selected folder. Permissions are then added/removed and Saved.
What's not happening is the saved changes aren't being refreshed in the Gridview, also after doing this process once selecting another folder doesn't refresh the Gridview either.

I have a gridview in a web page that shows some data from a table; in the same page I have a button that onClick executes a SQL Server job (the job has 9 steps and it takes around 20 seconds to execute).
How do I modify my code so that the page is smart enough to wait until the job is executed and refresh the gridview with the new data? Currently this is what I have:
[Code]....
The last method (GridView1_RowDataBound ...) is for having the background to red if some condition occurs.
Right now, after clicking ImageButton0, there is an instant postback and the gridview is not updated

In 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 have a web form with some labels, textboxes, buttons and a gridview. The gridview has AllowPaging ="true". Girdview displays record numbers (hyperlinked), When I click on a record number in the grid view it populates textbox1. Then I hit the 'Search button to auto populate the form the that record data from the database.
My problem is when I am on say 5th page on my grid view and click a record number to go in textbox1, and then click on the search button to auto populate the form, the gridview goes back to page 1.
How do I make the search button not reset/refresh the gridview?

I am looking for a way to refresh one custom control inside a method of another. Here is what I have:
A.aspx <- contains (B,C) custom controls below
B.ascx <- adds data to SQL databaseC.ascx <- contains (D) custom control below
D.ascx <- shows data from SQL database
Data is added to SQL in the C# B.ascx code-behind method. Upon a new row being added I would like a GRIDVIEW inside the D.ascx control to refresh and show that new record immediately.
Initially I had all the code on the same page, but then needed to cut it into separate custom controls. The code worked perfectly fine before and now I need this refresh to happen again. The code I used before to refresh the gridview was like this:
// sqlSummary.DataBind();
// grdSummary.DataBind();
In the end I also need to update the screen. I used an UpdatePanel before, but no longer have it. Not sure what the best way to update the screen is with the new data.

I have a gridview and a formview on one page.When a row of the gridview is selected, the details will load in the formview.When i edit the details (f.e. change a name) in that formview and save them, the gridview will just show the old data (=old name).I have to reload/F5 the page to see the changes in the gridview. Why isn't the GV updated when i do a databind() in the onclick-event of the update-button in the edittemplate of the formview?This example is using the northwind database:

I have a Gridview connected to an Access database using a Datasource and a query SELECT * FROM [Staff]. In order to update the grid view I have to do it in the IDE and click Refresh Schema. I have tried:
StaffList.SelectCommand = "SELECT * FROM [Staff]"
StaffList.UpdateCommand = "SELECT * FROM [Staff]"
StaffList.DataBind()
Staff.DataBind()
At runtime I want it to update the Gridview.
StaffList.SelectCommand = "SELECT * FROM [Staff]"
