Forms Data Controls :: Gridview Not Refreshing?

May 14, 2010

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.

Forms Data Controls :: Gridview Not Refreshing After Databind?

Jun 26, 2010

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?

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.

Forms Data Controls :: Refreshing Form GridView With Button_Click?

Mar 4, 2011

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.

Forms Data Controls :: Update Panel Not Refreshing After RowCommand From GridView?

Mar 7, 2010

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.

Forms Data Controls :: GridView Refreshing Data Prematurely?

Jan 3, 2011

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.

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.

Forms Data Controls :: Gridview Change One Field And Cause Change In Another?

Mar 7, 2011

I have a gridview in which I have several editable fields. The user wants a non-editable field to be modified if another field is modified in the same row. e.g. if Age>=65, Status should ="Retired"

I am using the following demo: [URL]

to create a bulk edit gridview so some columns are automatically editable and others aren't, with a single update button. I can set Status="Retired" in the xml generated, or as a rule in database table. But I'd like the status field in the gridview to change when Age is modified and to be shown to user before they press the single Update button. I'm using update panels and ajax on the page also.

JavaScript - Dynamically Change A Value On A Page Without Actually Refreshing It?

Apr 1, 2011

I have a label, let's call it LblA. I have a SqlDataSource, let's call it sds. Now, I have selected out and managed to get specific values using the select function. I want to set LblA's text to the value selected out of sds. I need this to occur every 5 (or as many as I specify really) seconds. I orignally used a timer object, however, for any of you who have used the timer object before, it likes to refresh the page, this makes it very hard to navigate off of the page; not only that, it's sloppy. Does anybody know a way to easilly update LblA's text from sds without refreshing the actual page.

I've read around and came to the conclusion that I need to use ajax, err... jQuery. However, I really don't know anything about the two except that they are both Javascript libraries?

Forms Data Controls :: How To Change Row Color In GridView

Feb 25, 2010

I am developing a scheduling system in which customers are alloted 15 minute timeslots (see example below). During rowdatabound event I know how to change the value of Cell(1) to NULL by using e.Row.Cells(1).Text = "" so Select option is not available for that timeslot. This works fine for someone who has taken only 1 timeslot.

Question is, when a Customer has for example 1:00 hour appointment (which is 4 x 15 minute time slots), how do I make the next 3 rows Cell(1) value NULL?

Is there anything like e.Row+1.Cells(1).Text = "" or some loop that I can run to take care of next few rows?
