.net - Id In Controls Automatically Changes?
Jan 11, 2011I'm writing a bit of jquery to access a dropdown, but .net automatically changes the id by adding ctl00$...
Is there any way to stop it from changing it?

Automatically Rebind Controls On Postback?
Dec 29, 2010Is there a flag or property value I can set to have my controls re-bind on every page load, instead of just the initial one? I'm still very new to ASP.NET, so I would like to do it properly (if such a way exists) before resorting to the first thing that "works".
I am working on a simple WebForms page, which boils down to a few SQLDataSource-bound Repeaters; for example:
<asp:Repeater ID="ExampleRepeater" runat="server" DataSourceID="ExampleDataSource"
OnItemDataBound="ExampleRepeater_ItemDataBound">
<ItemTemplate>
<asp:Label ID="DataboundControlID" runat="server" Text='<%# Eval("ExampleColumnName")%>' />
</ItemTemplate>
</asp:Repeater>
<asp:SqlDataSource ID="ExampleDataSource" runat="server" ConnectionString="example_connection_string"
SelectCommand="ExampleStoredProcedure" SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:Parameter DefaultValue="exampleValue" Name="parameter1" Type="String" />
</SelectParameters>
</asp:SqlDataSource>
After the user has interacted with my page, they can initiate a postback which will change the state of the database. I'd like the postback'ed page to reflect the changes to the database.

DataSource Controls :: Automatically Restore .bak Files?
Apr 23, 2010I want to restore .bak files from a server directory into database. The problem is it should behave automatically. Whenever a .bak file will be uploaded in that specified directory of the server that file will be restored. It may happen by using sql procedure which will restore all the .bak file which it will find at a certain time in that specified directory. Or, it may happen by using asp.net program which will run exclusively on server and call a sql procedure to restore a backup file whenever a backup file will come in that specified directory. But I am not getting how to figure out this ideas programetically.

View 2 RepliesForms Data Controls :: Automatically Tab To Next Textbox In Gridview?
Sep 9, 2010I have a gridview which contains asp.net textboxes. The user uses a barcode scanner which scans barcodes into the textboxes.
What I would like is to move to the next textbox after an item has been scanned in i.e. automatic tabbing to the next textbox.
Does anyone have any advise how I can do this?
What I have noticed is that when the user scans an item, the page does a full page postback even though the grid is in an update panel. And after the postback, the focus on the textbox just scanned in has been lost.
Forms Data Controls :: Get A ListView To Automatically Update Itself?
Sep 6, 2010I have a web page into which a user control is loaded. This user control contains a ListView. In the Page_Load event handler of the user control I have this code:
listView1.DataSource = TaskList; // Note: "TaskList" is a data table
listView1.DataBind();
It should be noted that the TaskList data table is actually instantiated in the web page. The user control then obtains a reference to it.
Everything described to this point works fine. Where I'm running into trouble is when I add a new row to TaskList. I had *thought* that the ListView control was dynamically connected to the data table, such that when I altered the contents of the data table in any way, that the changes would be automatically reflected in the ListView.

View 1 RepliesForms Data Controls :: Checkbox Automatically Checked After Delete In GridView
Apr 23, 2010I have a gridview control in which there is a column with checkbox. I will have to delete the rows of the grid selected by the checkbox. After the delete operation i am re-binding my grid we new datasource to populate latest data. The data is comig up correctly and the no of rows in the grid are also correct.
But the problem is that, if i select row 1 to delete and click on delete button, row 1 is deleted, grid is refreshed with new list, but row 2 checkbox is getting automatically checked. I don't know how this is happening. I have tried of writing code to uncheck all checkboxes after i rebind the grid. None of them are working. When i debug and see the items are actually showing as checked=false, but on the screen the check box is checked.

Forms Data Controls :: Automatically Set Page Index On DetailsView After Insert
Aug 13, 2010I 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.

View 10 RepliesDuplicate System.Web.UI.AsyncPostBackTrigger Controls Keep Getting Inserted Automatically - Causing Parser Errors
Apr 8, 2010I have an update panel with a number of [asp:AsyncPostBackTrigger...] controls, and everything was working fine. But now, something keeps inserting duplicate AsyncTriggers, and instead of simply being [asp:AsyncPostBackTrigger...] controls they're [System.Web.UI.AsyncPostBackTrigger...] controls, and I get parser errors as a result. So I delete the duplicate triggers, and they get re-inserted within a few minutes, seemingly randomly.
