Forms Data Controls :: Change Value Without Refreshing Gridview?
Oct 2, 2010
But i want to do that without refreshing page or gird my count value is increase which is i had.
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 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 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:
Here is my C#
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.
Why doesn't databind() work until I refresh the page?
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:
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 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 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)
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 have a page with lots of panels on it. Some of the panels are user controls and some are just on the page. I have a form on the page where you can add users and a gridview which is a user control showing a list of users.When a new user is added on the form I want to do gridview.databind() for the gridview in the user control. Does anyone know how to do this?
How to change the values in gridview on text change of templated control without databind again?the value of templated text boxes should change If i change the value of one of the templated textbox then accordingly(By mathematical calculations) the vlaues of all tempated textboxes should also change.
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.
I've a gridview with one textbox column and 1 label.
Based on language selection im changing master page and gridview will be bind with data based on language from database . When change the language the labels will be binding with data based on language . but textbox value is not binding properly.i.e;for example ¬†i've 2 languages English and Arabic . First i've logged with English Language gridview is binding correctly after chnage language to Arabic the textbox value is not binding is displaying with data previously whatever binded with english language. Other than this textbox remaining ¬†label data bindind with data in arabic language.
I have bounded Gridview through Wizard. It's working fine. but i want that if i add new data it should be visible in the gridview. But gridview not refreshing. I know i can perform this programmatically . but i want to do it in this case also.
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 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?
