Forms Data Controls :: PagerTemplate In GridView?

Feb 17, 2010

I have a gridview which i would like to design my own paging. i already have the first, next, previous, last linkbuttons and they work perfectly.But i need to show the total amount of records that are in the gridview (ie. Not total amount of records on each page of the gridview but all records on all the pages). I have set my gridview to display 5 records at a time.I need something like Pages 1 of 10 , Total number of records returned is 50 , Records 5 of 50. Can this be done?Also how do i make the index of the first page of the gridview = 1 instead of 0

Forms Data Controls :: Set Focus After Gridview Dropdownlist SelectedIndexChange Autopostback?

Feb 16, 2010

I have a Gridview that provides the user the student name for a particular class, a dropdown list to enter grades. If a grade of 'U' is given, a textbox appears in which the last day of attendance must be listed.

It works... though not as conviently as it could; the faculty would like to be able to tab from one dropdownlist to next in succession.

On each ddlGrades changes I write the value to the database and if a 'U' was chosen, display the textBox... but I can't figure how to set focus on the next ddlGrades control, or even the same ddlGrades control that initiated the postbock.

Below is my simplified .aspx followed by the codebehind

Forms Data Controls :: Need An Event Handler For DropdownList SelectedIndexChange Datagrid?

Aug 11, 2010

I've tried many different ways to try to get the selectedIndexChange to work for my dropdownlist. It doesn't seem to work, when I debug, I can see that the page is doing a PostBack but the method that suppose to be taking care of the select index change doesn't seems to be fired. I notice that there is no "handles" in many post so I was just wondering why it doesn't have it?On postBack I didn't rebuild the list so the selectedIndexChange value shouldn't reset to 0.Sub ddlAccess_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) ''handles ......?"
...

Forms Data Controls :: Getting - "'DropDownList1' Has A SelectedValue Which Is Invalid Because It Does Not Exist?

Dec 29, 2010

I've got a gridview which displays records from a table in SQL Server. Next I've got a details view which displays the details from the selected record. This works fine.

When the user selects a record, which then gets displayed in the details view, I'd like to make it possible for the user to edit the record. I've done searchs for this online, and found lots of responses, but none quite displaying an answer to the question I've got. I'm sure it is a simple thing I've done wrong, but at this point I don't know what it is I've done wrong. I've getting this error,"'DropDownList1' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value".

I've got a SqlDataSource to display the data in the details view. And then I specified another SqlDataSource to use for the dropdownlist control in the details view. I converted the field, in the details view, to a template field and have been replacing it. Here's the SqlDataSource controls definitions:

and here's the info for the details view:

Forms Data Controls :: Dropdownlist1 Doesn't Get Selecteditem "value"?

Forms Data Controls :: Manually Fire A GridView ItemCommand Event?

Mar 19, 2010

I've got a GridView control with LinkButtons in different cells. Currently when someone clicks a link, it fires the ItemCommand passing the CommandName and the ID of the item the link is bound to. That all works fine. I need to modify it now to not use links anymore. It now needs to show a popup balloon with a link (styled to look like a button) and when the link is clicked, I want it to do the exact same thing. I'm sure there are several ways of doing this, but for time's and consistency's sake, I'm copying the method used from another page we have that is already doing this. It has a hidden DIV on the page with the link in it. When you hover over a link, javascript repositions the div and makes it visible.

So what I need to do is pass my CommandName and item ID to the javascript so that it can trigger the postback when they click that single link. I know this is not the only way to get to the end result, but what I want to do if possible, is still fire the GridView's ItemCommand and set he DataListCommandEventArgs' CommandName and CommandArgument properties. Can someone explain how, under normal circumstances, clicking the LinkButton in the GridView fires the ItemCommand? I know that the LinkButton's click event is forwarded to the GridView but what gets sent from the client side that let's the server know the link was clicked?

Forms Data Controls :: GridView Attached To ODS In UC Won't Fire RowCommand / LinkButtons Disappear On Postback

May 11, 2010

[Code]....

I have a GridView attached to an ObjectDataSource (returning a DataTable) in a UserControl. The code is really simple. Data comes down fine when the page is first rendered. When I click on Select or Delete (inside TemplateFields), RowCommand is supposed to fire but it doesn't, the page goes straight to Page_Load. I literally have 0 other event handlers that are set on this control and everything else in the codebehind shouldn't even fire if it's a postback. Also on postback, the Select and Delete buttons disappear. It looks like the TemplateFields are still there but they're empty. The data fields (all of two columns) post back fine.
