I'm using CompareValidator to validate a TextBox control in FormView. I want to compare with a Label. I find however that when I select ControlToCompare, the Label isn't listed. The only controls to choose from are TextBoxes. And yes the Label does exist and is visible! Any ideas?
Many Thanks
Maj

That's because the Label control is not marked with the ValidationProperty[^]. So you either a) customize the label control or b) use a invisible textbox to contain the value beside the Label so that you can validate the textbox.

hello,
I've build myself a usercontrol with a couple of buttons to which I added event handlers. The control is loaded dynamically using LoadControl() of the Page object. Loading works fine, but the buttons click event in the usercontrol won't fire eventhough the page is posted back. Does anyone know this problem?
thanks a ton, matthias

is it possible you don't register your event after postback?

Follow these steps to add events to your user control.
a) Declare the event within the user control’s code module
public event EventHandler Click;
b) Create a method to raise the event
protected virtual void OnClick(EventArgs e)
{
if (Click != null)
{
Click(this, e);
}
}
c) Raise the event from within the user control’s code.
private void Button1_Click(object sender, System.EventArgs e)
{
// You can add your code here
// Then call the OnClick method.
OnClick(e);
}
As obvious now, you have to handle this Click event (declared above) on the Host or Parent web form.
Happy Coding

Someone to help me please.
I want a checkbox as part of my gridview and also use the checkbox to select the rows that are checked.
How do know the rowindex of the checked row and iterate thru the checked rows?

Depending on the size of the GridView you could try:
foreach(row in gridview)
checkbox = row.findcontrol(check box id);
if(checkbox.checked)
this row is checked
endforeach
Obviously the above will need some interpretation (and off the top of my head I'm not sure whether its the row or the cell that is the INamingContainer?)

I have an application which communicates with WebServcie.I installed the application and the WS on a srever of test,i've got all the results i'm waiting for.But when I installed the Web site and the WS on the WEBFARM, the Web site did no longer communicate with the WS. The site can communicate with the WS installed on the server of test.And another site installed on a site different from the WEBFARM can communicate with the WS installed on the WEBFARM.
The problem is that the Web site installed in WEBFARM cannot communicates with the WS installed on the same WEBFARM. What to do!

It is working fine on Development Server Cassini but doesn't work on IIS5.0 and 5.5

How do you define your custom handler? How do you configure that handler?

Hi Sandeep,
Please check the code and let me know.
Imports System.Data
Imports System.Data.SqlClient
Imports Microsoft.Reporting.WebForms
Partial Class Member_Members
Inherits System.Web.UI.Page
Protected Sub btnSearchMember_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSearchMember.Click
Dim con As DataAccess = New DataAccess()
Dim conLessons As SqlConnection = con.SQLConnnect()
Dim cmd As SqlCommand = New SqlCommand()
Dim _DataReader As SqlDataReader
Dim _DataSet As DataSet = New DataSetMember()
Dim _ReportDataSource As ReportDataSource = New ReportDataSource()
Try
conLessons.Open()
cmd.CommandType = CommandType.Text
cmd.Connection = conLessons
cmd.CommandText = "Select AutoID, ForeName, SurName From Members Where AutoID=" & TextBox1.Text & ""
_DataReader = cmd.ExecuteReader()
_DataSet.Tables(0).Load(_DataReader)
_DataReader.Close()
conLessons.Close()
ReportViewerMembers.LocalReport.ReportPath = Server.MapPath("~/Member/ReportMembers.rdlc")
_ReportDataSource.Name = "DataSetMember_Members"
_ReportDataSource.Value = _DataSet.Tables(0)
ReportViewerMembers.LocalReport.DataSources.Add(_ReportDataSource)
ReportViewerMembers.LocalReport.Refresh()
Catch ex As Exception
If conLessons.State = ConnectionState.Open Then
conLessons.Close()
End If
End Try
End Sub
End Class

in one crystal report i have one formula field
my formula contains no errors but the answer is not coming.
plse correct the following
local numbervar hours;
local numbervar minutes;
local numbervar seconds;
hours := hour({tbl_jip.start_time}) * 3600;
minutes := minute({tbl_jip.start_time}) * 60;
seconds := second({tbl_jip.start_time});
local numbervar start=hours + minutes + seconds;
local numbervar hours1;
local numbervar minutes1;
local numbervar seconds1;
hours1 := hour({tbl_jip.end_time}) * 3600;
minutes1 := minute({tbl_jip.end_time}) * 60;
seconds1 := second({tbl_jip.end_time});
local numbervar end=hours1 + minutes1 + seconds1;
local numbervar tot=end-start;
local numbervar RemainingSeconds;
local numbervar Hours ;
local numbervar Minutes;
local numbervar Seconds;
Hours := truncate(tot / 3600);
RemainingSeconds := tot - (Hours * 3600);
Minutes := truncate(RemainingSeconds/60);
Seconds := tot - (Hours * 3600) - (Minutes * 60);
totext(Hours,"00") + ":" + totext(Minutes,"00") +":" + totext(Seconds,"00")
where start_time & end_time are the 2 fields in tbl_jip table

Are you trying to say that "want to combine one query which conatains data of three tables related with them: Categories with Product , Item with Product"
something like this:
select C.*,P.*,I.*
from Categories as C,Products as P, Items as I
where P.IDCategory = C.ID and I.IDProduct = P.ID
|
|
|
|
|
No.i have no query problem i have a problem that which control is used to bind in this format

HI Imran i have ddone this its better to create custom control than using DataGrid or Repeater any thing create a custom control and develop logic you can do any thing with as you are going to write all those controls in render method ?
|
|
|
|
|
Thanks for ur reply sandeep
i will try to create custom control

DataGrid with TemplateColumn will solve your problem. Inside the TemplateColumn use a table to structure the data the way you want.

I need to pass a variable to the controlid of a ControlParameter so i can tell a Gridview which row the dropdownlist im editing belongs to.
What would be the best moethod for setting the control id?
Thanks.
|
|
|
|
|
Basically, the ControlParameter does not support the DataBinding event so you cannot use a data binding expression to set the ControlID property of the parameter, and your choice is to do this in code. Also, you need to be aware that the ControlID property needs to be updated before it is used to populate the value, if it happens after then you'll get an error as the specified control is not found. Normally, the ControlParameter uses its ControlID property to evaluate the parameter value in the overridable Evaluate method which occurs in the LoadComplete event of the Page instance. So you can put your code to update the ControlID in the events (of the data source control or the Page instance) that happens before the Page_LoadComplete and of cource after the data source control is built. For example, you can use the Load event of the data source control:
protected void SqlDataSource1_Load(object sender, EventArgs e)
{
ControlParameter para = SqlDataSource1.UpdateParameters[0] as ControlParameter;
para.ControlID = "GridView1$ctl0" + (GridView1.EditIndex + 2) + "$DropDownList1";
}
where the EditIndex property of the GridView control will give you the index of the row being edited, this is a zero-based value, however the index used in the UniqueID of the dropdownlist is a one-based value and it is counted from the header row. Therefore, you have to add 2 to the EditIndex to get the correct number used in the UniqueID.

Hi,
I have used below code (asp.net 2.0) to Save the Table (GridView 'GrdDynamic') in Webpage into a microsoft WORD file(.doc). But the below code Writes the Entire Web Page into Word file. How can I Save only the Portion (few Controls) of the page?
Response.Clear()
Response.ClearHeaders()
Response.ContentType = "application/msword"
Response.BufferOutput = False
'Response.Charset = ""
'tw.WriteLine("Weekly Report")
GrdDynamic.RenderControl(tw)
'Response.AppendHeader("Content-Disposition", "Attachment; Filename=demo.doc")
Me.EnableViewState = False
Response.Write(sw.ToString())
Dim fileToDownload As FileInfo = New FileInfo(strFileName)
Response.Flush()
Response.WriteFile(fileToDownload.FullName)
Response.End()

Jay
