I've created a new ASP.NET Dynamic Data website and have used LINQ-to-SQL for the framework. I start up the application and it displays my tables fine and I can browse them - but it doesn't give me any create/update/delete abilities - all I can do is read? I didn't change anything from the defaults - what gives?
View 1 Repliesmy form is having a label and a button, assume that you opened my website in ur system through url and now when u click the button it has to read a text file from the specified path in ur machine and display the data in label. i mean whatever machine is running my program it has to read the data from specific path from current running client machine.

i am creating dynamic textbox onRowCreated event and its creating without any issue but the question is how to read value of created textbox when the use hit on update button?
here is my code:

I have gridview created dynamical and added text box to the footer so I can insert into the gridview but I'm using findcontrol but it saying the value is null.

I used PopupControl Extender to display row details from a gridview, and need to update the two textboxes, but the changed value in the textboxes did not get picked up when click the update button on the popup window, so I need to get client side javascript to read the new changed value from these text boxes. However, I tried a few way, none worked for me, not sure what is wrong.
1. Add a javascript function in the .aspx file and use onclientclick of the linkbutton control to call the function, I got error of "Microsoft JScript runtime error: Object required".
<script language="javascript" type="text/javascript">
function newTextValue(textbox)
{
var text = document.getElementById("TextBox1").Value;
alert(text);
}
</script)
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("GalleryTemplateName") %>' Height="20px" Width="230px"
style="text-align: left"></asp:TextBox>
<asp:LinkButton ID="LinkButton2" runat="server" Font-Bold="True" CommandArgument='<%# Eval("GalleryTemplateId") %>'
oncommand="LinkButton2_Click" OnClientClick="newTextValue(this)" >Update</asp:LinkButton>
2. Use ScriptManager.RegisterClientScriptBlock in the aspx.cs file, :
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "changevalue", "alert(document.getElementById('TextBox1').value);", true);
but the alert window did not showup, that means the client javascript did not run? I just use an alert window to test to see if the textbox value is picked up. Note, I used Ajax Toolkit PopupControl Extender, all codes are in an update panel.
I have created some dynamic textboxes with standard content.Does anyone know how can I read the content of these textboxes (assuming that user modified the standard content) when I press one button?This is how I am creating the textboxes:
foreach (string name in listOfNames)
{
TextBox tb = new TextBox();
tb.Text = name;
tb.BorderStyle = BorderStyle.None;
tb.BorderWidth = 0;
tb.Font.Name = "Arial";
tb.Font.Size = 8;
}
I am executing a long-running Oracle stored procedure from .NET. The procedure takes about three hours to run. Ideally, the user should be able to kick off the procedure, close the browser, and come back later to check the results.
The problem is that the connection to the Oracle procedure is lost after exactly an hour. As you would expect, the Oracle procedre runs to completion if it is executed from SQL Plus. Strangely enough, it will also run to completion if I run in debug mode on my local machine (I start two threads, one of which executes the procedure. I set a breakpoint on the second thread).
Here is my connection string:
data source= (DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=serverx)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=TestSID)))
Some relevant sections from web.config:
<sessionState mode="InProc" cookieless="false" timeout="3000" stateNetworkTimeout="72000"/>
<httpRuntime executionTimeout="18000" maxRequestLength="2097151" />
Any thoughts as to why the connection is being lost in exactly an hour, and what I can do to maintain the connection until the procedure finishes?

I have a loop which creates for each item ID a Dynamic created checkboxlist control
how do I create a dynamic validation control on a dynamic checkboxlist?
If there's a better way to accomplish what I'm attempting I haven't found it yet. That being said, I have create a gridview like the one here,[URL]And with some minor tweaking it working great for all my fields, checkboxes, etc. The issue is my last column is another gridview, and I'd like it to function the same. that is, a dynamic gridview inside of a dynamic gridview. I get that I have to create it initially with null values or it won't show up. I guess what I'm having trouble figuring out is instead of go will null data in the parent gridviews column, do I place my blank child gridview. Do I create and bind the child gridview first, or second. Generally just not sure. Also, as far as storing the data from the child gridview goes, will each one need it's own datatable?

View 2 RepliesI'm working on a small standalone .NET app needs to refer to some tabular data and its only just selects and at most these tables have 250 records. Previously developers have used a SQL server database. Would I get a performance advantage if I simply convert the table data to XML and read from that? Also is there any kind of performance advantage over keeping database files in the App_Data folder for ASP.NET and attaching them dynamically as opposed to managing them separately? And this is probably a silly question, but if I do it that way does it mean that I don't have to install SQL server separately on the client's computer?
View 2 RepliesI am displaying selectable rows in a gridview. The selected row uses a stored procedure to display all the fields in a formview when the Select button is clicked.
Only a small subset of the fields in the selected row are editable. When I click the Edit button only the EditItemTemplate fields show up, the read-only fields from the ItemTemplate disappear. I want the read-only rows to remain visible with the editable rows.
If I include the read-only fields in the EditItemTemplate, I get an error when I click Update on the FormView. The error states that there are too many parameters being passed to the stored procedure to update fields. How can I continue to show the read-only fields with the editable fields on the FormView and avoid getting the input parameter error on the stored procedure for the Update command?
i am having my text file data as follows

I have NHibernate sessions cached in the ASP.NET session.
I came across a situation where a user edited an object so it's in their first level cache in the ISession. Another user then edited the same object.
At this point User1 still sees their original version of their edits where as User2 sees the correct state of the object?
What is the correct way to handle this without manually calling session.Refresh(myObj) explicitly for every single object all the time?
I also have a 2nd level cache enabled. For NHibernate Long Session should I just disable the first level cache entirely?
Edit: Adding some more terminology to what I'm looking to achieve from 10.4.1. Long session with automatic versioning the end of this section concludes with
As the ISession is also the (mandatory) first-level cache and contains all loaded objects, we can propably use this strategy only for a few request/response cycles. This is indeed recommended, as the ISession will soon also have stale data.
I'm not sure what kind of documentation this is for it to include both probably and then immediately say the session will have stale data (which is what I'm seeing).

View 1 Repliesin tat i was binding the table values like name,price and two textboxes for quantity and another one for total textbox for calulating total depends on quantity with price.
in my database table i have a row that contains minimum quantity=50 and maximum quantitiy=99 and price=0.66.and the min and max qty with price value varies.
i.e) if i enetring some quantites for example 51 during tat time it will fetch the between 50 to 99 price .ie)0.66 and caluclate the total value according to the quantity price i.e)51*0.66 and displayed in total textbox..
i dont want to use button to calculate the total value for each rows.
i entered the quantity at the same time the total will be calculated according to the quantity price.
I have a bulk editable gridview. I want to find a way of keeping a running total up to 100 in each row when the user is entering values into the editable columns. I then want to save this data.
The running total column (Total) is a bound column and not editable by the user.
