Forms Data Controls :: After Page Index Changed, Only Rows In First Page Are Accessible?
Jan 7, 2011
I have this function:
[Code]....
I set itemsRead and startRowIndex in ViewState:
[Code]....
This is my PageIndexChanged event:
[Code]....
My purpose is to modified some data only for current page in a gridview. I call this function in page load and GridView_PageIndexChanged events. When it's called in page load event, it works fine. But when it's called in PageIndexChanged event, only the rows on the first page in GridView are looped through. For example, if I click page 5, the rowStartIndex becomes 100 = 5 x 20 (my pagesize). The if condition becomes itemsRead >= 100 andAlso itemsRead < 120. But after itemsRead is increased to 19, the For each gridViewRow loop stops and the if condition is never satisfied.

I have a gridview with paging. I have a style set for a selected row (highlights the row in light orange). What i would like to do is that each time a user chamges the page, the selectedIndex & selectedRow automatically becomes the 1st row of the selected page. So i would like to see the orange highlight on the 1st row of the page to indicate that the row has been selected.
I have tried GridView1.SelectedIndex=0 but this only seems to select the index of the 1st record in the whole datagrid. Does anyone know of how to set the 1st row of the page to the selected row each time the pageindex is changed?

I have 3 nested grids as Parent/Child/GrandChild and I have assigned SqlDataSources to all the grids at declaration time. I place the SqlDataSource next to each grid as follows.
<GridView>..</GridView><SqlDataSource>..</SqlDataSource>
Because of this I am not doing anything in RowDataBound(...) event. But I used the RowCreated(..)event of Parent and Child grids to access session (Please look at the select statements of Child/GrandChild grids).
Parent grid's RowCreated(..) event puts the value in the session which is used by Child grid. Child grid's RowCreated(..) event puts the value in the session which is used by Grand Child grid.
GrandChild grid has paging enabled and whenever I click on page index, Child and GrandChild grids goes blank. Parent gird doesn't go blank because its select statement doesn't take any "select parameters".
how to overcome this problem. I am attaching .aspx and .aspx.cs files

I have a Datagrid on ASP.NET web form which I have bound to a data source and set it to have 10 records per page. I also have a hyper link column on the Datagrid , such that a user can navigate to another page (details page) from the list. On the details page, they have "Cancle" button to return to the Datagrid pageI am looking for sample code snippet on the Server Side on how to specify the page index to set the Datagrid after data binding. The idea is to ensure the user navigates to the same page index they were on.

I have a grid view where the user can change pages at either the top or the bottom of the grid view. I want the view to go back to the top whenever a user changes the page, whether they are changing from the top or the bottom. I've tried using anchors and javascript to achieve this but it does not work. The javascript is executed and the user is taken to the top of the gridview, this can be seen by placing an alert after the javascript to change the view. But the last thing that happens on the page change is that the window is returned to it's previous position (the bottom of the page). Is there any way of doing this?

I have a gridview which is fairly straight forward... I've added paging to the gridview which functions correctly. However, after clicking any one of the page buttons (next page/last page), it appears some sort of a label is being displayed in my web form saying "NewPageIndex: 1". This changes from page to page displaying the actual index of the page. Why is this displaying? The only thing i can think of is the size of my gridview (Right now set to 1500 lines per page) . here is my gridview control html code:

I have a panel which has a repeater within it. Within the repeater I have a few controls. One of those controls is a Drop Down list which has an OnSelectedIndexChanged event. I can get this to fire without issue but I cannot find my DropDownList control within that repeater within the SelectedIndexChanged event . The repeater has an OnItemDataBound event and I can use the RepeaterItemEventArgs to find the control using e.Item.FindControl("ControlName") without issue but when that event occurs is NOT when I need to find the DropDownList.
What I want to do is have another control's Visible property be set to "true" when the value of the DropDownList meets a certain value. As far as I know I can only do this during the SelectedIndexChanged event and I can't change the signature of the event by trying to use RepeaterItemEventArgs.

I've got a GridView in which all rows are set to Edit by default.
I want to be able to save the rows only where changes have been made. At present, my code will only update the first row from my GridView to my database. I've had a look on the internet, and think that the Getchanges might be able to help me, but I'm struggling to work our how exactly to implement it in my scenario.

Right now I have a gridview with databind. My menu item consist of the 7 days of the week. Everything works fine except for one thing, the page index. Right now by default it loads the results for Monday. If I click on Pg 2 for Monday, and then I click on Tuesday, the page number stays at page 2 and the data remains the same. I have to click on Pg 1 or Pg 3 before the data would refresh and change the result to Tuesday's data.
I've tried adding databind() to the MenuClick event but if Monday has 3 pages, and they click on Tuesday which only has 2 pages, it would give me an error. Also the adding of the Databind() still doesn't fix the page index when I click on a different day.
How do I reset the page index when the user clicks on the day.

I wonder if there is a clevcer way of setting the correct page of a DetailsView after inserting new data? I have a DetailsView bound to a LinqDataSoure. Now, if I use this DetailsView to insert new data, everything works fine, except the fact that the DetailsView switches back to the "old" page index after leaving InsertMode.
This is somehow understandable, because it can't know which index the new entry will have, but unfortunately neither do I. So I was looking to the LinqDataSource_Inserted event where I can get the new Entry, but because the DetailsView.SelectedValue is read only, I can't just set it to the new entry. So. I might have to use the PageIndex property, but then I would need to know the index of the new Item, which I don't have either.
So, my only idea know is to store some information from the new entry, wait until everythings bound again, loop through the DetailsView to find my new entry an set it's index for PageIndex. But also here I have two problems:
1) The new entry (e.Result from LinqDataSource_Inserted) has not yet filled it's primary key, as this is of course created in the DB, so it's very difficult to identify the new entry properly
2) I don't know how to access each DetailsView page information without actually making it the active page.
So, my question, is there a clever way of doing this? In the past, I've been using SqlDataSource. Although the problem is basically the same, I could solve the two major problems by 1) Insert with Stored procedure which gives the new primary key back and 2) run through
"(((System.Data.DataRowView)MyDetailsView.DataItem).DataView.Table.Rows[i].ItemArray[0])"
to compare the keys. Both I can't get to work with LinqDataSource.

I have created an application in asp.net 4.0 and entity framework4 . I have also implemented the routing feature introduced with this version of asp.net.I have page which displays a list of products and the paging is taken care of using datapager control.Now, when the user selects a particular product (using the checkbox provided besides it), I show the selected product's name on top. As the user goes on selected products the product_names are added on top. This functinality I want to achieve using javascript. When the user switches between different pages to select a product the already selected product names should be retained between different pages. I want to implement this whole fuctionality using javascript.My problem is how do I retrieve the page index from the datapager so that I can retain the selected values.Is there any other better way of doing it. I had already faced numerous problems in using javascript because of the routing functioanlity. But still I first want to see if there is a solution using javascript.
