Here is one of my article on session, Hope this will give you some more idea on session.

Are you deleting any sub folder under the application root folder in your asp.net code. If so, it will restart the AppDomain.

Hi I have nested gridviews bounded to data tables. On child gridview delete event I'm trying to fetch the parent gridview row index somehow to fetch the child gridview through find control and databind it to show the updated changes. However I am fetching the the wrond index through my code as its returning the row number of the child and not the parent. Here's my row delete event for the child. 
protected void gvSec_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
GridView gvtmp = (GridView)gvComp.Rows[e.RowIndex].FindControl("gvSec");
DataTable tmpdt = (DataTable)ViewState["SecTab"];
if(tmpdt!=null)
{
tmpdt.Rows.RemoveAt(e.RowIndex);
}
gvtmp.DataSource = tmpdt;
gvtmp.DataBind();
ViewState["SecTab"]=tmpdt;
}

Try the following code. You can get the parent GridView row by
((GridView)sender).Rows[e.RowIndex].Parent.Parent.Parent.Parent
Also you can get the control or cells value of the parent gridview using
((GridView)sender).Rows[e.RowIndex].Parent.Parent.Parent.Parent.Controls[0] collection

Thanks for the reply Mr. Ramesh.  It solved my problem, can you please explain a little how this Parent.Parent works ? I mean logically .
((GridView)sender).Rows[e.RowIndex].Parent.Parent.Parent.Parent
How does .NET drill down the parent by using this parent property/method ?
Thanks, Mike.

Is there any built in function in ASP.NET Like print_r in Php which displays information about a variable in a way that's readable by humans.

The question is where you want to display this text? if its on the browser with nothing you can use Response.Write() function to write whatever you want on the rendered output.

Hi,
I must have searched every forum on the internet and tried every custom function going to try gain control over textboxes in the insert template of my formview using VB code behind without any success and its starting to bug me.
Consider the following scenario:
If I have a formview with ID: "Details"
and a textbox called: "CampaignTextBox" in the <insertitemtemplate>
and wish to set the .text value of "CampaignTextBox" to "Hello World"
I believe the most obvious method is as follows:
<br />
Dim Dynamic_Text As TextBox = CType(Me.Details.FindControl("CampaignTextBox"), TextBox)<br />
Dynamic_Text.text = "Hello World"<br />
It doesn't matter how I manipulate this code I cannot get my code to find the control - I get a null reference exception - "Object reference not set to an instance of an object.."
Other details about my page that may affect this (possibly):
1-It is a page that uses a master page, does this cause issues?
2-If my formview is within a div would this make any difference?
Could anyone give me any clues or if at all possible an example using the parameters given above and save me from going bald before I get to 30?
Thanks
Andy

In case anyone suggest these, I have also just tried omitting "Me"
<br />
Dim Dynamic_Text As TextBox = CType(Details.FindControl("CampaignTextBox"), TextBox)<br />
and trying to add the extra level of "row"
<br />
Dim Dynamic_Text As TextBox = CType(Details.row.FindControl("CampaignTextBox"), TextBox)<br />
and experience the same problem.

ur coding is correct but u need to make dummy binding to form view to make it build control hierarchy.
try this in page load,
If Not Page.IsPostBack Then
Dim arr As New ArrayList()
arr.Add(1)
Details.DataSource = arr
Details.DataBind()
End If
|

Hi,
thanks for your reply.
When I try the code in the page load event I get the following error:
"Both DataSource and DataSourceID are defined on 'Details'. Remove one definition"
What could cause this error message in this context?
I don't understand the need to create a dummy binding. Would you mind explaining as if I understand it I may be able to figure out where I'm going wrong?
Cheers
Andy

I have finally cracked it. No dummy databinds required or anything other than the findcontrol method.
The key is purely down to using the method at the correct time in the page life cycle.
I used the following to set a textbox to the current date and time.
where:
Formview ID = "Details"
Formview child Textbox to change ID = "Date_AddedTextBox"
(Textbox is in the insert template)
<br />
Protected Sub Details_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles Details.DataBound<br />
<br />
If Details.CurrentMode = FormViewMode.Insert Then<br />
<br />
Dim Test As TextBox = CType(Details.Row.FindControl("Date_AddedTextBox"), TextBox)<br />
Test.Text = Now()<br />
<br />
End If<br />
<br />
End Sub<br />
So ... if like me you have been to hell and back via the entire internet trying to do what seems like the simplest thing, trust your code as it is probably correct and try it at a time where the items have definitely been created and and data definitely bound (such as the event I used above) and you should have success.

This is how we can open a parent window from a chid window and the beauty to pass parameters
<code>
<a href="#" onclick='window.opener.navigate("forumTopics.asp?forumID=<%=forumID%>");window.close();'>myLink</a>

This isn't a question. I was having hard time doing this thing i wanted now I got the answer so I shared it. Somebody will be benefited

Rather than posting it in a fast moving forum, where it gets swallowed up and forgotten quickly, you could put it in the Wicked Code[^] forum.

I want users to be able edit a Word document that is on the server. I also want the server to host the Word application. I do not want the client computer to be required to have Word installed. Is this possible or is the only way to do it is to have the client have word installed?
|

If it is possible, it would require a third party component. ASP.NET itself plainly cannot do this, with what you get by default. That component would need to convert Word docs to HTML, send them to the client, use JS to create UI like word, then take the result and convert back to Word format. As Word can save as HTML. that may not be as hard as it sounds.

I'm not a Javascript person, so please be kind. I've got an asp.net 2 page that has a master page. I've got a javascript that works fine in a regular asp.net page within the same web. Move it to the page with the master page, and it won't work. Any help appreciated. Also, what's the difference between function setDifference(form) and setDifference = function(form)? Here's the basic stuff:
<script>
setDifference = function(form)
{
var x = document.getElementById('dtTxt1').value;
var y = document.getElementById('dtTxt2').value;
var dt1 = Date.parse(x)
var dt2 = Date.parse(y)
document.getElementById('resultTxt').value = (dt1.valueOf() - dt2.valueOf()) / (60 * 60 * 24 * 1000)
}
</script>
<asp:TextBox ID="dtTxt1" name="dtTxt1" runat="server" onkeyup="javascript:setDifference(this.form);" onkeydown="javascript:setDifference(this.form);" />
<asp:TextBox name="dtTxt2" id="dtTxt2" runat="server" onkeyup="javascript:setDifference(this.form);" onkeydown="javascript:setDifference(this.form);" />
<asp:textbox name="resultTxt" id="resultTxt" runat="server" />
|
|

|

This is creating a function, which takes form as a parameter, and is called setDifference. I don't think in this instance that it would matter if you removed the = function part. I could be wrong, I am no JS master, either.
What does 'won't work' mean, do you get any errors ? Have you tried using firebug in firefox to debug the script ?
