Dear,
if you are using Visual studio you have to use the codebehind directive because VS precompiles your application. if you use src, it means that you want to compile it straight away. if you using another developement suite u are required to use the src directive
Happy Coding

How Can I access the contrl of one page in another page.
|
|
|
|
|
You can create a public property for that control on the page in question, but this is not a great way of accessing data (for a web application).
|
|
|
|
|
If you are using cross postback in 2.0, use the "PreviousPage" object and type cast it to the called page and access it controls.

there's nothing wrong with the code.
Button1.Attributes.Add("onclick", "window.close();");
try changing the case of onclick to onClick.maybe some case-sensitivity issue.
|
|
|
|
|
ok, i will try, thanks a lot;)

Dear,
first check if your page_load event is working. i mean if the code in this event is getting compiled by putting a breakpoint at the beginning to this event.
if yes, the code seems working. put the button id as it is because it's case sensitive.
urbuttonid.Attributes.Add("OnClick", "self.close()");
Happy Coding

Hi!
I have a DB table that references it self to create a hierarky. If the ParentRoleId column is null then the Role represents a top level role:
Database columns:<br />
RoleId PK (Identity)<br />
ParentRoleId FK (Allow null)<br />
RoleValue
Now to the question: I'm using typed datasets as database access, but the generated code for the ParentRoleId column is of the type int and thus doesn't support null.
How should I create a workaround for this?

Aloha,
We have a datagrid with some templatecolumns that show datetime data in an European format (day/month-year).
Everything looks great, but they don't sort correctly. It looks like they are sorted like normal text strings, so day is considered before month and year:
11-05-2006 - should appear last, since it's later than all the other dates
12-04-2006
13-04-2006
14-04-2003 - should appear first
Any idea how to fix this?
Thank you,
|

You can set the datatype of the column you are sorting on to be datetime rather than string.
|
|
|
|
|
How? I thought the same, so I have looked high and low for such a property. I can't find any 
|
|
|
|
|
myDataSet.Tables(0).Columns(0).DataType = GetType(System.DateTime)
|
|
|
|
|
Yes, it would be easy with a dataset. Unfortunately we have a dictionary<int, object=""> where the object contains the data for a row in the datagrid.
The object contains datetime properties for the data we want to display in the datetime columns.
|
|
|
|
|
How are you then performing the sorting?
|
|
|
|
|
Implemented the OnSort event on the datagrid. The data is in an ArrayList format and I sort it using the ArrayList.Sort() method.
Maybe this can be changed to handle datetime values?
|
|
|
|
|
You'll need to alter that code to handle sorting on the particular data type - if you're using .net 2.0, i'd consider using a List<T> to allow you to use explicitely set types - by default the arraylist contains only items of Object type - it doesn't know how to sort them.

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.
