Forms Data Controls :: Refresh GridView In Web Forms?
Mar 1, 2011
I've a GridView , in this i'm populating values from database. And, Wt i've done is, if i click " Select " Command of each row all those colums values lik, id,name,age,sex,address wil b populated in resp textboxes.
Problem is I've a "Refresh" Button, Wt i wanna do is, i'm clickin rows randomly & populating values to textboxes, now the selected row was 3rd row means if i click "Refresh " Button, no rows shuld be selected & the textboxes should be empty.
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
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'm trying to update my gridview after inserting data but insert function cannot handle. I don't know what i am doing wrong. Functions are below. waiting for your comments.
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()
I have a gridview and which contain checkbox field too.If the checkbox is clicked and then delete button click, relevent record is deleted.This delete function is working properly.
problem Even though record is deleted,it does not affected in gridview.Deleted record is still remaining in the gridview.What will be the way that should I follow solve this problem?
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?
Before I begin, I would like to acknowledge that I might be using incorrect terms below due to my lack of experience.
I have a GridView bound to an ArrayList of Custom Objects. I have a button as part of each row, which when clicked, I delete the row from the Arraylist, and re DataBind() the GridView. While this deletes the Row, it causes the Page to be refreshed that takes the User back to the top of the Page.
E.g. If the User clicks on the button of a row at the bottom of the Page, after the deletion, the Page gets refreshed and the User is now taken to the top of the Page.
This is irritating especially in long lists i.e. GridView with many rows. (I don't want to use paging here.) Is there any way to avoid this, or mitigate this problem.
i am facing a problem to get a correct row index after i filter the data in table, it always keep the history row index in the table before i filter. i had a search button to filter the data in gridview,
I have the following gridview inside an updatepanel that makes the bind from a datatable:
[Code]....
What I intend to do and I'm not getting is the following: When i edit a textbox in a row with a new value, like Desconto textbox, i want that when that textbox looses the focus, to refresh the gridview with new values that result from changes in the value of the textbox. It's a new bind as i know, the problem is how to find the correct way to trigger the textbox textchanged event, at the moment nothing is happening. I created the Desconto_TextChanged event but when compiling, i receive a compilation error:
Description: An error occurred during the compilation of a resource required to service this request. review the following specific error details and modify your source code appropriately.
Compiler Error Message: BC30456: 'Desconto_TextChanged' is not a member of 'ASP.index_aspx'.
I have a gridview with four columns, all sortable.
I need to refresh grdiview onbutton click.So if user sorted data by column1 then on button click gridview will be refreshed without sorting (as data comes from database).
I have a gridview that has allowPaging and AllowSorting set to true. It is bound to a sqldatasource with the selectCommand firing a sql query. The sqldatasource has EnableCaching = true, and caching duration = "60". The idea is to run the paging, sorting, etc from the cache.
A separate dataUpdate event updates the data that is being loaded in the grid view, but I am not able to see the change in the gridview data till 30 seconds (caching duration) .
What is the best way to force refresh the gridview data by the dataUpdate event?
I came across this artice that tells to use CacheKeyDependency, but when I implemented it, the gridview gets refreshed at every dataUpdate event, but also the paging and sorting fires the sqldatasource Selectcommand sql query. I want this query to be fired only on dataUpdate.
I'm coding with VB.NET and have a webform that includes gridview. The gridview captures data via a db view. Also the view includes all the parameters of the tables.
The problem is: when start program, there is only 2 rows seen on gridview. then i can insert something successfully. And when i checked from db i can see the new data. But in my form, newly inserted data doesn't seen. Even i restart the whole program, gridview always shows only 2 entries.
I have a GridView in an update panel that is bound (in code-behind) to a business layer object. The first time this page is accessed, Editing, Deleting, Updating, etc. work fine. However, if I click my browser's refresh button, the functionality of the edit, delete, etc link buttons is gone. They do nothing.
I have a dropdown list within a details view that allows me to set 1 or many categories to a perticular record(in this case a photo). The select command in this case only displays those catetegories that are not already attached to the selected photo.
all works well and as you select a category and add it to the database the category is removed from the dropdown list and is added to a gridview which shows all categories that photo is stored with.
My Problem is that when i delete the category from the gridview the dropdown list does not delete with said deleted item unless i do a "click in URL bar and press enter" to totally refresh the page.....
how to refresh the dropdown list in the details view after the gridview item has been deleted?
Now, as you can see I've set up the commandargument, and was expecting to get to that in my code behind file. My code is as follows:
[Code]....
Ok...so far so good, and as long as I'm the only one working on the system it works fine. The problem is if this scenario happens:
* I go to the page and look at the gridview
* Someone else enters a new record into the database, causing the first row to contain a new record (not displayed in my browser)
* I click select.
What happens then is that, for some odd reason, I will get n numbers higher than the one I actually selected (n = num_added -num_removed).
I was under the impression that the commandargument wouldn't change for my session as long as I didn't refresh the gridview...?... There are no ajax or anything else messing with postbacks or viewstate as far as I can see..
I have a table on my page. I need to scroll down a little to get to that table. In that table i have som data that i edit and save to database. When the save is done i need to refresh the page( Response.Redirect(Request.RawUrl )) so it loads the new data to that table. When the refresh is done the page is on top again so that i need to scroll down again to see the table. This makes it very unusable for the user.
How can i refresh the page without it going back to top again? I tryed wrapping an updatepanel around the table but it didnt
I have a gridview binded with data and i am providing to user edit command button in gridview s row command event i opened the new page in modal popup to edit the selected id record and after modify i close the popup here i want to refresh gridview with updated data. here is the code i used to open editdocument page in modal popup from gridview row command event
I am using AsyncFileUpload to upload the file on OnUploadedComplete event i am binding the gridview with new datasource.On debugging its show that gridview is binded properly but after uploading the file gridview is not refreshed.My Gridview is not inside update panel
I have a page where the following code works to refresh an updated image, but it won't work in another page. (The Util.FindChild is an enhanced FindControl that I use.) I'm sure it has to do with the ModalPopupExtender not closing but I don't know what to do about it. I also use a ModalPopupExtender on the other page and it works--in fact, both are virtually identical since they both originate from the same user control.
I am using an ObjectDataSource in my FormView for INSERT.
Data inserts correctly to my backend SQL table, however as i am posting back a success/fail message to the same page, i have noticed that after a successful INSERT if it hit the Refresh button the INSERT is doubled up.
How can i stop a user pressing the Refresh button and doubling the INSERT?
Is there a setting somewhere or can i stop this programmatically within my ObjectDataSource_Inserting method perhaps?
I am refreshing my DataGridView by calling using the code below:
[Code]....
However I want to use templates in the DataGridView like this:
[Code]....
So I would NOT be calling FillDataGridView() from Timer1_Tick.My question is: what do I have to add inside Timer1_Tick so that it will refresh my DataGridView (the one with the templates)
