Error in compiling Page with Crystal reports

Hi all,

Following is my code for setting the data source for a cystal report which i m using in my project.

protected void DDL_Departments_SelectedIndexChanged(object sender, EventArgs e)
{
int deptid=int.Parse(DDL_Departments.SelectedValue);
EmployeesTableAdapters.Get_Employee_By_Department _emp_adapter=new EmployeesTableAdapters.Get_Employee_By_Department();
Employees.EmployeesDataTable _emp;
_emp=_emp_adapter.Get_Employees_By_Dept(deptid);
_rdc.SetDataSource(_emp);
CR_Emp_Viewer.ReportSource=_rdc;
CR_Emp_Viewer.DataBind();
}

but its giving me a compile time error stating

CS0121: The call is ambiguous between the following methods or properties: 'CrystalDecisions.CrystalReports.Engine.ReportDocument.SetDataSource(System.Collections.IEnumerable)' and 
'CrystalDecisions.CrystalReports.Engine.ReportDocument.SetDataSource(System.Data.DataTable)'

What do i need to do to solve this issue????

Also its surprising that a similar code i wrote in VB runs successfully.:confused::confused::confused:

I am using VS 2005, 2.0 framework.

I believe reportdatasource(_rdc) expects IEnumerable Collection, while you are passing DataTable, which is not an IEnumerable Collection. So it throws the error.

If you are in 3.5, you can call DataTable.asEnumerable()

here you need to pass _emp.Rows collection which is IEnumerable collection.

Try out this. I have never found this before, Hope it works.

But SetDataSource provides four overloads from which one does accepts a DataTable.

I am pretty confused as to why it recognises the data table as an IEnumerable. Confused | :confused:

this is weird.

Try to do this, and see if it works or not:

Employees.EmployeesDataTable _emp;
_emp=_emp_adapter.Get_Employees_By_Dept(deptid);
DataTable dt = _emp.Table;
_rdc.SetDataSource(dt);

Pass the Table to the SetDataSource rather than your class. Thumbs Up | :thumbsup:

Probably checkbox is losing state on load event of Page,check it carefully.

By the way,if you had problems with internet connection then delete one post of your same question.

I guess you are binding the Gridview data on Page_Load and you are not checking the Postback properties, which reset the Grid Check box field.

Try this

if(!Page.IsPostBack)
   {
    //BindGridViewData. 
   }

Hope this will help you. Big Grin | :-D

There is a class GridViewRow, on SelectedIndexChnaged event of Grid, Read the current Selected Row in GridViewRow, then you can read each and every column from it. Even you can read directly the data.

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
   {
       int  ID= Int32.Parse(GridView1.Rows[GridView1.SelectedIndex].Cells[0].Text);
   }

Note : I assume, Cell[0] of Grid contain your ID

Hope this will help you Big Grin | :-D

Fixed table header

Hi All,

I have a table used to display few items, that table's width is reduced and is using horizontal scroll bar to view all the columns. When that is displayed in IE it is howing the headers properly means the header width is equal to the column width of the items.
when it is viewed in Mozilla or Safari browsers the header widths are reduced but, items column widths are remaining same, which is looking very odd. And when it is viewed completely without horizontal bar in all the browsers the headers widths are good again.

Can anybody please advice me its header widths remain same in all the browsers along with its horizontal bar.

Thanks in advance,
Mohammad Abdul Aleem.

The problem is IE6 renders scrollbar outside the working area where others renders it inside.
