Hello,
I am still learning ASP.NET, if you need additonal information or have questions please let me know.
I am creating a ASP.NET site (C#) in Visual Studio.NET that is utlizing a grid view to pull data from a SQL DB. I am using the ASP.NET membership provider model for the website authentication. Access to the site is only allowed with the correct username and password.
I have a webform call Document Checklist. The webform is connected to a SQL table called document_checklist. I need the Document Checklist webform to display only those documents that the logged in user has not approved. I need for the user to click on the checkbox for those documents that he has approved and click the submit button to update the SQL DB. The SQL DB contains the following columns user_name, document_name, document_url date_added, date_approved and checkbox.
I have been trying to work throught this and am not certain how to proceed.
1. I am not certain how to query the SQL DB against my LoginName I have tried a few things, but am not able to capture the value of the LoginName and compare it to user_name value of teh SQL DB field. (The formatting of LoginName from ASP.NET and user_name from SQL DB is identical.)
2. I do not know how to utilze checkbox to update the SQL DB.
3. I do not know how to capture the date that the checkbox was checked and insert it into date_approved
The code is below. I am not certain how to list the CheckBox_Changed in the code behind.
Thank you in advance for your help.
aspx C# code
<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="document_checklist.aspx.cs" Inherits="members_document_checklist" Title="Untitled Page" %>

to get the info about currently logged in user .

Thank you for your response. I am not certain how I would use that to compare that value against the Username data field in SQL to only display values where loginname is equal to Username (in SQL).
Below is my code for my aspx page.

<br />
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server"><br />
<h2>DOCUMENT CHECKLIST</h2><br />
<br />
<br />
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1"><br />
<Columns><br />
<asp:BoundField DataField="user_name" HeaderText="Username" SortExpression="user_name" /><br />

Why would you want to show 77000 records ?

So the user can find the one they want!! 
|

Better approach is put a search option , when the user puts a Search Criteria the appropriate results would be displayed ,
Because you could not expect a user to move through all 77000 records

yes, but if he still wants all the records he can have paging enabled.

Hi,
Yes but the problem the problem is if the paging is enabled also the page is not not displaying due to huge data i think .Is there a way to Display all the records(77000)
Thanks

have you calculated the time taken to fetch the data in which back end you are using... because if it takes long time in database then you have to follow indexing... and in the database if the query returns the value soon then there is prolem in your code... Any how can you send your code for further clearance....

Hi ,
Search option is not accepted here. So is there any other way to display data.
Thanks

What do you mean by 'not accepted' ? Do you mean you have a client who wants to show 77000 records on one page of a website ? Can you think of a single website that shows this much information ? If not, how do you know it's possible, assuming it was at all advisable ?

Hi All,
Please tell me how to write XML query in Asp.net.
I hav temple.xml file which contain data of temple.
now i want to apply search on it.
|

Well, this is not an ASP.NET question really, it's a C# or VB.NET question. You can use an XMLDocument and the DOM to search your XML, or I believe you can use LINQ, if you're using 3.5

Hi Priya ,
U cannot directly Query an XML Decument in ASP.Net 2.0 ,
However you need to parse them to check for the desired result ,
It got significantly easier with LINQ introduced ,
As per your requirement if you are using ASP.net 2.0 create an instance of XMLTextReader and read thru the document
|
|
|
|
|
XMLDocument is far better for searching.

Yeh Chris,
I was wrong i did some searching XMLTextReader is a fast forward way of reading data from an xmlDocument .
Much like DataReader ........

You say you are trying. What have you tried ? Where are you stuck ? Why do you need to use a datalist ?

OK, so this is for a class ? Or you're just teaching yourself at work ?
You've added link buttons, why do you expect them to show images ? What have you done to make that work ?
