Hi im trying to add an image to a column in a gridview, but when i try to update my table with the path for the picture in the show table data, i get the error
"can not use the result pane to set this fields data to values other than null"
~/Pictures/Daughter.jpg is the text that im trying to enter into the column for PictureUrl, where Pictures is a folder that contains the images.

what is javascript?when it is use?
|
|
|

Javascript is client side code that runs in the browers not at the server. There are many uses for javascript, most of them have to do with when you don't want your web page to have to post back to the web server. Instead you write javascript so the code can run on the client side without having to post back to the web server. I think if you did a simple web search (google) you would find more complete information on javascript and its use.

Hi all,
I am building composite control which has 2 expandable properties. But I have problem with DefaultValues of those sub-properties.
Here is scenario:
I set “Red” value for my “Thumbnails-BorderColor” (expandable) property with DefaultValue(typeof(Color), “”) attribute.
In source-view in my control tag there is inner attribute look like this:
<thumbnail bordercolor="Red" height="56px" perpage="3" width="96px">
I run page, my thumbnail border color is red like it supposed to be.
If I change value to nothing (remove “Red” value), now my source-view control tag look like this:
<thumbnail height="56px" perpage="3" width="96px">
(seriazable)
I run the page, my thumbnail border color is STILL red?! If I wait for 2-3 minutes. again run the page there is no color around thumbnail, like it supposed to be when i removed “Red” value initiaily. So I guess this waiting period cleared out ViewState??
However, if I remove DefaultValue attribute, my soruce-view control tag look like this when I remove value:
<thumbnail bordercolor="" height="56px" perpage="3" width="96px">
(it’s not serializable)
this works good when I run the page but I want "serialzable-way" 
thanx

I found a problem and solution.
To make sub properties for my control I was referring to this article Server Control Properties Example,
in which property of sub property class don't have "set" accessor, therefore new sub property value cannot be updated so last
value which was persisted in ViewState was used.

Hi guys,
I know how to use the SqlMembershipProvider, and setting up and tying it into the relevant controls is simple enough, it works very nicely in my app.
However I have no idea how to get a handle on the actual fully initialized SqlMembershipProvider or SqlRoleProvider objects to manualy work with them.
I suppose the question is, how do i initialize it from the Config settings?
Cheers chaps

I am using Visual Studio .NET 2003 to develop the application. My issue is that i had to generate a Word Report with password from an ASP.NET web application.
After much try i got the dll Microsoft Word 11.0 Object Library and with the help of which while trying to generate a word document with password from a application it was throwing a runtime exception.I had to imersonate the user as it showed an acces violation.
COMException (0x800a175d): Could not open macro storage.
When performed a search with this, i came to know the necessity of configuring the Word application of the server with DCOMCNFG - as setting the word to be run under interactive user mode etc. But that is very risky as listed in the links,
http://support.microsoft.com/kb/q288366/ -- (Explains how to configure with DCOMCNFG)
http://support.microsoft.com/kb/257757/
Can any body tell me how to solve this without using DCOMCNFG ?
The following link tells me that it can also be achieved by saving the
document as XML and manipulating the XML.
http://www.thescripts.com/forum/thread374627.html
Is it possible to set a password while generating with the XMl... i don't think that it is possible but still....
Then how to stream that file to the client ?
If any body could give me any suggestions or links i'll be grateful...!
If anybody comes across any link or any thing please do reply ....
I will be very grateful...

hi friends
I have completed my login page by validationg username and password. After that i can able to login into the second page.
But the error which i am facing is when i am calling the second page directyly without calling the first page the second page is opening.
I have used session variables for username in the second page. Inspite of that it is opening. How to create a particular session for that. Waiting for ur reply. How to block the firstpage.
Thank You

In the second page in the pageload event check to see if the session variable you set when the user is logged in is null (C#) or nothing (vb.net) If it is then redirect Response.Redirect("page1.aspx") That way you force the user to log in.
Hope that helps.

Use the setting in the configuration file and forms authentication, let the framework handle verification for you, that's why it's there.

Oga make 2nd gridview visible false on page load ovent
You can add your command button in gridvew in desig time by choosing edit columns option.
if you are not using select button for any other purpose i'll suggest use select button and change its text to "what ever you want"
then use gridviwes RowCommand event
following line of code may be helpfull for you.
int rowid=Convert.ToInt32(e.CommmandArgument);
GridViewRow gvRow=this.Gridview1.Rows[rowid];
swith (e.CommandName)
{
case "Select":
Gridview2.visible =true;
break;
}
hope this will give you idea.

hi,
You can write the code like this
Button1.Attributes("onclick") = "javascript:history.go(-1);"
or
you can use this in HTML
or
you can use link like set href="javascript:history.go(-1);"
Back

I have a site which should recover customer details using a telephone no. entered by calling txtPhoneNumber_TextChanged
TextBox ID="txtPhoneNumber" runat="server" relative" AutoPostBack="True" textChanged="txtPhoneNumber_TextChanged" OnLoad="Page_Load" />
It calls the code behind the first time i use the site.
But the next time I try to use the customer either by drop down of previous details or manual entry id does not call the change method.
What I really need is a field exit event ??
Has anyone any ideas
Thanks
