You have declared the num in class but i think assigned value in Page load
after button click the page gets loaded again and num can't persist its value
Use session to store value of num or
add this in page load event
if(this.Page.IsPostBack)
a = 1;

Session is not advisable use ViewState

THnaks for ur reply but it is giving the recebt one report details only,not the first report details,I have tried like that also.
CrystalReportViewer1.ReportSource = Server.MapPath("HOReport\rptEmployee.rpt")
CrystalReportViewer1.ReportSource = Server.MapPath("HOReport\rptEmployeeGradation.rpt")
CrystalReportViewer1.DisplayGroupTree = False
CrystalReportViewer1.DataBind()

No man,
It should be like this
CrystalReportViewer1.ReportSource = Server.MapPath("HOReport\rptEmployee.rpt")
CrystalReportViewer1.DisplayGroupTree = False
CrystalReportViewer1.DataBind()
CrystalReportViewer2.ReportSource = Server.MapPath("HOReport\rptEmployeeGradation.rpt")
CrystalReportViewer2.DisplayGroupTree = False
CrystalReportViewer2.DataBind()

From the toolbox i have placed two crystalreportviewers on my webform.
Then i have given the code like u suggested.
When i take two CrystalReportviewers data is overlapping (bcz,both the reports are dispalying at a time),and with a single viewer we can display only one report's data.
What i have to do???Please give me a solution.
kissy

|

|

put a table there and put these two viewers in two rows and try it out
OR
Anyway this is not the right way to do this.
What you have to do is, while creating crystal report, add two subreports and set the reports in each subreport.
and call thru only one crystal report viewer

CrystalReportViewer1.HasRefreshButton=true
and when i am clicking on it it is giving an error like
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: CrystalDecisions.CrystalReports.Engine.LogOnException: Logon failed.

When i used the below code,

It is giving the same Exception,Means in both the conditions it is giving same error.
I have checked both my code and dbconnection.
Why it is still arising same Exception.
Bcz the end user must able to refresh the data from frontend only.How to solve.
Thanks for ur responses once again.

provide your database info
//set the database loggon information.
//**Note that the third parameter is the DSN name
// and not the Database or System name
reportDocument.SetDatabaseLogon("pchitriv", "Windows2000",
"TestDB_DSN", "testDB", false);

Hello,
I think I am posting this question again but I'm quite frustrated as I haven't found any way around.
I have a databound datagrid in which New/Blank rows are added to this datagrid on a button click event. This button is outside the datagrid and not in the footer. The datagrid populates well and I can do the edit/update to the already created records. I recently had to add a new checkbox field to my data table. This chekcbox field is to be included in this datagrid. The chkbox works fine for previously created records but as soon as I hit the 'Add New Row' button I get the following error :
Exception Details: System.InvalidCastException: Conversion from type 'DBNull' to type 'Boolean' is not valid.
Source Error:
asp:checkbox id="cbcurrentdriver" runat="server" autopostback="true" enabled ="false" checked='<%# DataBinder.Eval(Container.DataItem,"currentdriver") %>' />
My code for adding a new/blank row (on button click event) is as below:
RefreshGrid()
Dim ds as DataSet = DataGrid.datasource
Dim blank as DataRow = ds.tables(0).NewRow()
ds.tables(0).Rows.insertAt(blank, ds.tables(0).Rows.Count)
DataGrid.EditItemIndex = ds.tables(0).Rows.Count-1
DataGrid.DataBind()
and my checkbox template column is as below:
asp:templatecolumn headertext="Current Driver?">
itemTemplate>
asp:checkbox id="cbcurrentdriver" runat="server" autopostback="true" enabled ="false" checked='<%# DataBinder.Eval(Container.DataItem,"currentdriver") %>' />
I really am clueless on this one. everything seems fine. Nulls are allowed on this field in my datatable.Please help!
Thanks.

Try to change your itemplate column to this.
C#
<itemTemplate>
<asp:checkbox id="cbcurrentdriver" runat="server" autopostback="true" enabled ="false" checked='<%# DataBinder.Eval(Container.DataItem,"currentdriver")== System.DBNull ? false : DataBinder.Eval(Container.DataItem,"currentdriver") %>' />
</itemTemplate>
VB
<itemTemplate>
<asp:checkbox id="cbcurrentdriver" runat="server" autopostback="true" enabled ="false" checked='<%# Iif(DataBinder.Eval(Container.DataItem,"currentdriver")== System.DBNull, false, DataBinder.Eval(Container.DataItem,"currentdriver")) %>' />
</itemTemplate>

Mark

Hello Mark,
A big thankyou for your prompt help and your time to read my post.
I jumped to the solution and did a copy-paste (VB code), but I get the following error :
Compiler Error Message: BC30201: Expression expected.
Source Error:
asp:templatecolumn headertext="Current Driver?">
itemtemplate>
asp:checkbox id="cbcurrentdriver" runat="server" autopostback="true" checked='<%# Iif(DataBinder.Eval(Container.DataItem,"currentdriver")== System.DBNull, false, DataBinder.Eval(Container.DataItem,"currentdriver")) %>'
enabled="false" />
/itemtemplate>
what am I doing wrong?

try to replace the logical codition "==" to "=".
VB - Old Code
<itemTemplate>
<asp:checkbox id="cbcurrentdriver" runat="server" autopostback="true" enabled ="false" checked='<%# Iif(DataBinder.Eval(Container.DataItem,"currentdriver")==System.DBNull, false, DataBinder.Eval(Container.DataItem,"currentdriver")) %>' />
</itemTemplate>
VB - New Code
<itemTemplate>
<asp:checkbox id="cbcurrentdriver" runat="server" autopostback="true" enabled ="false" checked='<%# Iif(DataBinder.Eval(Container.DataItem,"currentdriver")=System.DBNull, false, DataBinder.Eval(Container.DataItem,"currentdriver")) %>' />
</itemTemplate>

Mark

Thanks MArk, it has worked finally, you were thinking right, just that I had to use 'Is System.DBNull.Value' in place of '==' or '='.
Thanks a ton for your solution, it worked like magic.

<mymultipage:Tab Text="Info1" ID="tab0" ToolTip="Info1"></mymultipage:Tab> <br />
<mymultipage:TabSeparator></mymultipage:TabSeparator> <br />
<mymultipage:Tab Text="Info2" ID="tab1" ToolTip="Info2"></mymultipage:Tab> <br />
</mytab:tabstrip><br />
</td><br />
</tr><br />
</TABLE><br />
<br />
<mymultipage:multipage id="MULTIPage1" runat="server" width="780" height="300px"><br />
<mymultipage:pageview id="Info1"><br />
<TABLE id="ThirdMainTable" cellSpacing="10" cellPadding="0" width="780" border="0"><br />
<br />
<tr><br />
<br />
<td width="10"><br />
</td><br />
<br />
<td width="760"><br />
<br />
<TABLE id="tblLocation" cellSpacing="0" cellPadding="0" width="100%" border="0"><br />
<tr height="25"><br />
<br />
<td width="20%"></td><br />
<br />
<td width="50%"><br />
<br />
<asp:CheckBox id="chk1" runat="server" Text="CheckOnce"></asp:CheckBox><br />
<br />
</td> <br />
<br />
<td width="30%"></td><br />
<br />
</TR><br />
</TABLE><br />
<br />
</td><br />
<td width="10"></td><br />
</tr><br />
</TABLE><br />
Can anyone please suggest me a best way to do this?
Thanks
