Forms Data Controls :: Invalid Object Name #temptable Refreshing Schema On GridView
Mar 23, 2011
I am not sure why this is happening, but when I drop a GridView on the page and set up the SqlDataSource to point to a stored procedure - when I go to refresh the schema and add my session variable, I get an "Invalid object name #temp_table_Name" I have the appropriate read permissions on the tempdb. The user and password info are correct. The temp table is created in the stored procedure before executing the query.

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]"

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'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 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 am new to asp.net development and I have a employee Web form that is part of a larger wesite. The webform uses a Gridview control which receives data via SQL Server tables so the web form has a SqlDataSource ID="SqlDataSource1" defined. When the page loads, the connection string automatically populates the rows of the gridview (which is a all employees).
I am attempting to create a customized sub search wherein the user can reduce the search to one person by providing either firstname or lastname, department etc within a textbox and then selecting the same from a dropdown list. Finally the user clicks the submit button (which is onclick in codebehind).
When I try to do the above I get "System.InvalidOperationException: Both DataSource and DataSourceID are defined on 'GridView1'. Remove one definition." It seems that once I define the DataSource and DataSourceID in the form, it is illegal for me to do it again in the codebehind. Is there a way to refresh the Gridview that I already have with code from a button_click. I have code attached.

I have two gridviews tied to a SQL backend both being displayed within an update panel. Both the gridviews have a linkbutton connected to a rowcommand. When clicking on one of the rowcommand link buttons, the database is updated and the update panel is refreshed (moving the record to be displayed in the other gridview in the panel). However, when the rowcommand from the other gridview is clicked, the code is run and the database is updated, but the update panel is NOT refreshed.I have debugged it and have found that the code is running as expected. It fires off the function and updates the database. If I click away from the page and then go back, it does show the data in the proper gridviews, so I know that the code is working.

On my aspx page I use a popupmodalextender to show (and edit) some data that is contained in a gridview (gridview is on the same page). Popup works OK and also the editing of the data, but when I close the popup (from code behind) the data in the gridview is not refreshed.

I am trying to implement a GridView. This GridView needs to allow users to read and update data from a single table. The data in the GridView is the population for a city/state. Please note the use of the DISTINCT as some cities in a state have multiple postal codes. Regardless, to edit this information, I'm trying to use the following GridView:
[Code]....
The information is displayed as I would expect. My problem is with editing. When I click the "edit" link, a TextBox associated with the population is displayed as expected. When I click "update" though, my change fails to persist. I fired up SQL Profiler and found that the data in the Grid is being refreshed before the UPDATE statement is being sent. Because of this, the original value is being sent. what am I doing wrong? I just need to update the Population value of the cities with the value entered by a user.

I have a Gridview that shows my data, I allowed it to have Editing and Sorting. I have achieved refreshing my GV with <META HTTP-EQUIV="Refresh" CONTENT="15">. however, when I Edit and it hits the time to refresh, I loose the Edit mode and starts at the beginning of the grid (I need to find the data again.) Is it possible to still have the refresh (15secs) then when Iam in EditMode, the Refresh stops, then after I have clicked UPDATE. the refresh time starts to count again. (i use VB)
