I am having a problem with the gridview and formview. I have a gridview setup to show products and have a select button to clock on to give you the details of the product in a formview. I have the gridview setup for paging at 5 rows. In the page.aspx.vb I have on the SelectedIndexChanged event
FormView1.PageIndex = GridViewMain.SelectedIndex
This all works great until I go to the next page in the gridview and try to select a product on that page and the form view does not sync up. I really need a soultion for this. I could use the 2 page soultion for the master/details view however I would like to avoid it if possible...
Tell me how can i avoid reconnection to database while paging in repeater?

View 3 RepliesI've got popup (using javascript) working in a kind of gridview. When you click a button on one grid, it displays a popup window containing another grid of information, based on the row clicked in the first grid.
This works well... I've enabled editing in the grid that is popped up. When you click edit though, the popup window disappears. If I click the display button in the first grid though to bring the popup window visible again it displays, and is now in edit mode.
Is there a way to make postbacks in the popup not close the popup?
in the gridview control when user edit the row and click on update button to save and then click on refresh button (IE) it execut the update event again.
how should i avoid if the user click on refresh after it updates the row?
I have a parent gridview5 with child gridview 6, today i deployed it to our dev server and on that server we have alot more records, so for the nested gridviews i need to enable paging on the parent gridview5. Doing so works fine, until i make a selection within the child gridview6, once any selection is made, and i try to page the page throws an error, i have the following bound to the parent gridview5.

In my asp.net Page I am using gridview. I am binding the gridview on page load and on paging event with one method. suppose as Bindgridview1();.
There is one search button for searching the records of user with different method suppose as Bindgridview2(); .
when I am searching the records with Bindgridview2(); paging doesn't work and directly bind with Bindgridview1(); which is on page load when I clicked next page.
I have boundfiled column inside gridview and made the column as invisible by setting visible="false".
But while exporting the gridview to excel I am getting the Header text alone exported. Wherever the column's visibility is set to false the header text should not be exported. After binding the gridview I have set the column's visiblity to false so it won't export the column values.
The problem is to stop exporting the header text to excel. Let's say column index is 10
public class GridViewExportUtil
{
public static void Export(string fileName, GridView gv)
{
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AddHeader(
"content-disposition", string.Format("attachment; filename={0}", fileName));

Call JavaScript function on GridView Row click using jQuery in ASP.Net works great!, but if I want to have a first column with an image button so the user can click only there to select a row it always produce a postback when using a button field, how can I avoid that postback while having an image button for the selection click in the gridview?

I'm trying to extend the GridView control to enable sorting and paging for any situation.
When using my control I am fetching data from a database and filling a DataSet with it, then binding the GridView upon every page load. My first question would be, is this the correct approach?
To sort the GridView I am overriding the OnSorting method which stores the sort expression and direction in the ViewState, then creates a DataView and utalises the Sort method to sort the underlying data. It then sets the Data Source to this DataView and rebinds the GridView.
Paging is handled by OnPageIndexChanging which simply sets the PageIndex property and again rebinds the GridView.
My problem is; when any control causes a postback my GridView is no longer sorted, presumably because it is persistently rebound. If I don't rebind it then the GridView is empty on postback since the data isn't automatically stored in the ViewState. I have considered saving the data source in the ViewState but I would assume that this is bad practice for large amounts of data? - also DataViews are not seralisable.
The only solution I can think of currently is to override OnDataBound and sort the data every time. This results in a double sort when paging triggers a postback which seems inefficient. Code illustration of this below,
[Code]....
I'm looking for the cleanest 'best practice' solution as this is a learning exercise more than anything else.
I have a GridView that is populated via a dataset that contain 1 table. I have enabled paging on my GridView.
In my Updating event, I handle the new values and call a store proc to update my database with the new values for the selected row. In order to minimize the call to the DB, instead of getting back a new dataset with the updated values, I simply update the row of the dataset that I have in session with the new values and then I bind back my gridview.
The problem that I have is since I have let's say 5 pages of 10 row... If I update a row on the first page as soon as I click update, the gridview will show the new values. However, if I select page 3 for example, click on update and update the values, once the update is done, the gridview will still be displayed with the old values.
I have a table named [vacation time] with the colums startdate and enddate the table is conected with the [permits table]with the colums permname and permdays(int). i have to create a warning message for the user if the ((startdate)-(enddate)>permday) to avoid the update statement in my grid view.
View 2 Replies I am using linkbutton in my gridview to avoid the use of querystrings. The gridview is filled from a dataset.
I almost have it working but the text the linkbutton is displaying does not vary as a function of what row it is in. I need a way to associate the text of the linkbutton with the row it is in.

My question is, can I control the style of the paging element separately of top and bottom, I have set the paging to appear in both top and bottom of the gridview, and I want to see that the top pagination is little high up in the page, to do that I used the cssClass and set margin-top:20px and made the position: absolute, this does change the position of the top paging area and set it rightly for me, but the bottom pagination has also come up as a result and now sits inside the grid data!!

View 8 RepliesI hoping someone could answer a question for me. I am relatively new to developing web applications with .NET and I have question I can't seem to find a straight answer to. When allowing paging of a GridView control, how does retrieve the data per-page? Is all the data stored into an object, and then displayed x amount of rows at a time? Or, when moving from page to page, is it executing each time but restraining the result to the specified amount of rows?
