C# - Datagrid Getting Selected Value (delete Xml Node)?

Dec 26, 2010

Lets assume there are 2 columns in my datagrid:

<asp:View ID="viewRemove" runat="server">
<asp:DataGrid ID="dgRemove" runat="server" AutoGenerateColumns="False" OnDeleteCommand="dg_DeleteCommand">
<Columns>
<asp:BoundColumn DataField="name" HeaderText="names" />
<asp:ButtonColumn ButtonType="PushButton" Text="Delete" CommandName="Delete" ></asp:ButtonColumn>
</Columns>
</asp:DataGrid>
</asp:View>

The first column displays names from a xml file and the button column just hold delete buttons so i can delete the corresponding item to the left of it (1st column).

How exactly can i retrieve/pass this selected value to a function? In other words when i press the button to the right of the name, it passes the value so i can work with that to remove the corresponding xml node. (using XPath)

XmlDocument XMLDoc = new XmlDocument();
XMLDoc.Load(file);
XPathNavigator nav = XMLDoc.CreateNavigator();
var node = nav.SelectSingleNode("/root/name['" + ??? + "']");
node.DeleteSelf();
XMLDoc.Save(file);

C# - Windows Desktop Search - Force Re-index / Index Now From Command Line?

May 14, 2010

I'm working on a project where we're using Windows Desktop Search (WDS) to index files on a web share and then later allow the user to search via a website for documents in the share.

These documents are transferred to the share via FTP, however it would seem that either the computer never goes idle to index or at some point the indexing stops. Is there a way from the command line or within the program itself to force this to happen without having to re-invent the wheel? Using .NET 3.5 and C#.

Data Controls :: Delete With Confirmation Using Details View Delete Command Button

Nov 7, 2011

I am interested in building an intranet document management system to be used from Internet Explorer using ASP.net, VB.net, and MS SQL Server but have no experience in doing a project like this. Supported file types would be txt, pdf (from scanner or imported from file system), or jpg. What concepts I should look at researching/learning about to build the system in a way that files will be stored as small as possible, retrieved and displayed quickly, and secured. The users would be spread out over a regional area covering 4 states.

Datagrid Page Index Changed?

Mar 14, 2011

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 am binding months to a list 0-13 items default selection is 0 months duration, and years 0-8 items and 0 years is the default selection.As I know there are always going to be 12 months in a year, I could use selectedvalue or selectedindex without any perceived problem. Is there a reason why I should not use either/or of the two properties to select a list item?

SQL Server :: Using SQL INSERT Command With DataGrid - Must Declare The Scalar Variable Error

Mar 28, 2011

OK, this may be a little difficult to explain, so I will try my best and post the code I currently have.

I have a table with a list of usernames. I have the list of usernames displayed on a page through a GridView. What I am attempting to do is for each username in the column "adminUsernames", I need to insert a set of values in another database table for EACH "adminUsernames" that exists. Example: There are 2 adminUsernames vales in 2 seperate rows. These are "Admin 1" and "Admin 2". For each adminUsername values (Admin 1, Admin 2), I need a row interted in another database table. Maybe the code that I have (that does not work) will help you see what is happening:

I keep receiving this error when running: [Code]....

Automatically Generate Delete Command For GridView Not Working

Nov 9, 2010

I have a GridView and a SqlDataSource, which I have set to automatically generate Delete/Insert/Update statements. I then just enabled Deleting on the GridView, and usually away I'd go. For some reason though, the row is not being deleted - the page is posting back but the row is still there. When Delete is clicked, RowDeleting does fire though. What possible causes could this be?

Edit: SELECT command:
SELECT id, templatename, CASE WHEN type = 'W' THEN 'Weekly' WHEN type = 'M' THEN 'Monthly' WHEN type = 'Q' THEN 'Quarterly' WHEN type = 'S' THEN 'Six-monthly' WHEN type = 'A' THEN 'Anually' END AS TypeText, CASE WHEN invorcred = 'I' THEN 'Invoice' WHEN invorcred = 'C' THEN 'Credit' END AS 'InvOrCredText', nextinvdate, lastinvdate FROM InvoiceTemplates WHERE (sageaccount = @sageaccount)
