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?

It have to use the VB.net with my code. I know how to reads two 'sheets', and then insert that info into a database.
I know how to get the information from excel using a SELECT query and System.Data.OleDb.OleDbConnection, and OleDbDataReader. Problem is taking this information and inserting it into the access database.
Any help or suggestions?

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...
Regards,
Sivaprasad

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.

Hi there,
I'm using .net 1.1 and I have the following settings in my web.config:
<authentication mode="Forms">
<forms name="TRVAUTH" loginUrl="/logon.aspx" protection="All" timeout="20" slidingExpiration="true" path="/"></forms>
</authentication>
<authorization>
<allow users="?" />
</authorization>
And then, later on...
<location path="profile.aspx">
<system.web>
<authorization><deny users="?" /></authorization>
</system.web>
</location>
This config worked fine. Whenever an unauthorized user requested the profile.aspx, he was redirected to the logon.aspx, authorized and sent back to the profile.aspx (if authorization was successful). That was yesterday. I've done some bugfixing last night and it was a long night. Today I startup my web-project and do what I did a million times for the last 10 days: I request (unauthorized) the profile.aspx. But WTF, my browser shows me a login dialog instead of showing me the logon.aspx like he did yesterday!!!
What could I have possibly messed up?
Thanks in advance!

Matthias,
There are a couple of questions to narrow down the scope:
+ Do you have this problem with different browsers?
+ Do you by any chance to disable the anonymous access in the IIS snap-in?
+ Do you have this problem with other web pages?
|

hi there,
I already figured what the problem was: I've build in a bug where I'd append (manually) a ReturnUrl to specific pages. One shouldn't do that  .
Anyway, thanks for your reply and a good day from rainy berlin.

I would like to know whether the caching will have an impact in the case of Network Load Balancing. If there are more than one application server, how to do the caching? I have a doubt that if data is cached in one server and the next request goes to some other server, the cached data may not be there. I would like to know the answer for this with/without IP Affinity masking.

Hi I want to do paging in the datalist.
For that i wrote the code:
public int intStart=0;
private void Page_Load(object sender, System.EventArgs e)
{
if(!IsPostBack)
{
ViewState ["Start"]= 0;
list();
}
}
public void list()
{
conn.Open();
SqlDataAdapter sda = new SqlDataAdapter("select name from sampledatagrid",conn);
DataSet ds1 = new DataSet();
intStart = (int) ViewState["Start"];
ViewState ["PageSize"]=7;
sda.Fill(ds1,intStart,(int)ViewState["PageSize"],"sampledatagrid");
dlistSample.DataSource=ds1.Tables[0].DefaultView;
dlistSample.DataBind();
conn.Close();
}
private void lnkPrevious_Click(object sender, System.EventArgs e)
{
intStart = (int) ViewState["Start"] -(int) ViewState["pageSize"];
ViewState["Start"] = intStart;
if (intStart <= 0 )
{
ViewState["Start"] = 0;
}
list();
}
private void lnkNext_Click(object sender, System.EventArgs e)
{
int dlistcount = dlistSample.Items.Count;
intStart = (int)ViewState["Start"] + (int)ViewState["pageSize"];
ViewState["Start"] = intStart;
if ( dlistcount < (int)ViewState["pageSize"] )
{
ViewState["Start"] = (int)ViewState["Start"] - (int)ViewState["pageSize"];
}
list();
}
}
Here the values are displayed correctly in the Datalist., But If i cliks the Next or previus linkbutton(<< or >>) at the time it shows the error:
Object reference not set to an instance of an object.
Error occured in this line:
intStart = (int)ViewState["Start"] + (int)ViewState["pageSize"];
How can we solve this one?

on the pageindexchanged event of the datagrid write this code.
DataGrid.CurrentPageIndex = e.NewPageIndex;
after this line call the datagrid to load the contents again
this will work fine.
