Hi,
I am using asp.net 2.0. In this,i am using Cross Page Posting. From the second page, i am trying to reference a control (Label) in the prevoius page using 'PreviousPage' property.
Here, in the first page, that Label control is placed within the "asp:Content" tag. (ie I am using MasterPage's ContentPlaceHolder).
Page.PreviousPage.FindControl("lebelid") method return null.
In case of normal page ( without Masterpage), it works fine. Can anyone help me in this? Thanks in advance.
Regards,
Jay

Because the Label is placed in the Content control, that also means it is later put in the ContentPlaceHolder control which is a naming container. So you need to get reference to this control fist before accessing the Label control.

I am tried with refering the NamingContainer before refering the actual control (Label), which is placed within that NamingContainer. It also gives me the output null.
In my previous page, the Label control present within the tag,
<asp:Content ID="Content5" ContentPlaceHolderID="BodyContent" Runat="Server">
</asp:content>
In my second page (using same masterpage) code behind file, i am refering like this,( in Page_Load event)
ContentPlaceHolder myContent = (ContentPlaceHolder)Page.PreviousPage.FindControl("BodyContent");
Still it returns null.

hi,
Is it possible to bind the datagrid with the database table rows as columns. In ASP.NET2.0 there is a control called "Details view". i need exactly the same style in ASP.NET1.1.
That is i want the table headers to be in the first column and the row in the next column.
I will the data by a sql statement with select statement.
eg: select ssn,fname,lname where ssn = 1234

I have a vb.net web page with a dropdownlist - the page displays a customer record. The options in the dropdownlist are hard-coded.
I'd like to have the dropdownlist show the value saved in the database when the user pulls up a customer record.
However, when I bind the control to the dataset (default view 0) the dropdownlist displays the value from the database on several lines eg:
o
p
e
n
instead of "open" on one line.
Should I be setting the value of the dropdownlist a different way other than using the databinding ?
Thanks

I'm using vb.net. I used the databinding 'wizard' to set the source (eg I click on the control then click on the elipse button in the databinding property)
After selecting the column from the default view, visual studio sets the datasource as - DataBinder.Eval(Dscustomerdetails1, "Tables[customers].DefaultView.[0].type")

Hi,
I'm not sure if this is what you are looking for but here goes.
Tree Looks like this
Tree Node 1
Tree Node 1 a
Tree Node 1 b
Tree Node 1b i
Tree Node 1b ii
Tree Node 1 c
Lets say you want to hide Tree Node 1b ii
TreeView.DataSource = SiteMapDataSource1;
TreeView.DataBind();
TreeView.Nodes[0].ChildNodes[1].ChildNodes.RemoveAt(1); //This hides tree node 1b ii
Hope this helps.
Remember in order to do this you have to programatically bind the TreeView. Note remove the DataSourceID from the IDE first.
Good luck
Cheers

Create a div element and place the datagrid inside it. Then insert the below mentioned javascript(Popup menu script-Dynamicdrive.com) in the head of the page. Call this javascript from div element "oncontextmenu"
<Head>
<script language="javascript">
//DynamicDrive.com
var defaultMenuWidth="150px" //set default menu width.
var linkset=new Array()
//SPECIFY MENU SETS AND THEIR LINKS. FOLLOW SYNTAX LAID OUT
linkset[0]='<a href="http://dynamicdrive.com">Dynamic Drive</a>'
linkset[0]+='<hr>' //Optional Separator
linkset[0]+='<a href="http://www.javascriptkit.com">JavaScript Kit</a>'

Please don't cross post.

What do you mean? Where is it that you delete the div tag? In the browser? In page source? In the design view?

When I click save button i am calling a function to RegisterClientScriptBlock
Page.RegisterClientScriptBlock("keyClientBlock",jScript);
How should i disable this...I cant remove this function bcoz i have one page inside another page...

If you are re-posting a form by reloading the page, the browser sends up this warning. This is a security precausion, so that the user won't re-post data without being aware of it.
The warning might be able to disable manually in the browser, but not by using script.
