You can write following code on SelectedIndexChanged event of first dropdown list. and then load the data based on first dropdown's detail. and in second drop down keep AutoPostback off.
/***************************** Code *************************************
Protected Sub Dropdown1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles SelectCmpCmb.SelectedIndexChanged
Dim str As String
str = "Select CompanyName from Company where
CompanyName = '" & dropdown1.Text & "'" (Name of your first dropdown list)
dropdown2.DataSource = dbaccess.ExecuteDataReader(str)
dropdown2.DataTextField = "GroupName"
dropdown2.DataBind()
End Sub
Note : Here dropdown1 is name of first dropdown list.
and dropdown2 is name of second dropdown list.
I hope this will help you.

i think you don't have datagrid property in javascript as it is server control specifically for asp.net
My suggestion for you is that create a custom control and write the html tags in the render method which is good solution I think

In the item databound event, you should be able to get a reference to the hidden field for that row. When you have that, you should then be able to pass the ClientId of that control to your javascript function in the button click event.

Something like this (in the OnItemDataBound event of your grid):
Dim myHiddenField As HtmlInputHidden
Dim myButton As Button
myButton = DirectCast(e.Item.FindControl("buttonId"), Button)
myHiddenField = DirectCast(e.Item.FindControl("hiddenId"), HtmlInputHidden)
myButton.Attributes.Add("onclick", "JavascriptFunctionName('" & myHiddenField.ClientID & "');")
Then in your javascript function you can use that id to populate your hidden field with whatever data it is that you need.

Hello,
I'm working with active directory and I've used:
directorysearcher search =new...;
search.propertiesToLoad.Add("cn");
That give me the user name. now if I'm also getting the "memberof" property I'm getting alot of groups for the user.
Is there a built in function that tell me if the user is in a specific group instead of writing my own function that will run on all the groups that the user is a member of them and compere?
some thing like:
bool x=isCurrentUserMemberof("myGroupName");
Hope i was clear enough.
Thanks.

Your web hotel should have some instructions on how you set up your database on their specific database server. Provided of course that you have an account that includes database support...

So you're counting down to a certain time... Now if you keep this time (or datetime) in a session variable, you'll be able to calculate how to 'further-countdown' right?? This makes your javascript continue in stead of start over and over again...
|
|
|
|
|
Thanks for your reply.
But how can i retrieve the value of the session variable into the javascript. Pls help me in this regard.
Thanks and Regards,
Sushanth_CP
|
|
|
|
|
You can't, but you can set the session variable as javascript in your page...
use the Page.ClientScript.RegisterClientScriptBlock function to write javascript to your page..
|
|
|
|
|
You can also access the session value in javascript by setting it to a hidden field and then access it in JS.
|
|
|
|
|
Thanks for the information...
it will be greatful if u can provide me with more information on hidden field and JS access.
Thanks and Regards,
