Hello
Any help appreciated.
I need to convert this:

Protected Sub grdMaster_RowDataBound(ByVal sender As Object, _
ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) _
Handles grdMaster.RowDataBound
Dim objListItem As DataControlRowState
objListItem = e.Row.RowState
Dim intMAsterID1 As Integer
If e.Row.RowType = DataControlRowType.DataRow Then
Dim grd As GridView
If objListItem = 5 Then
grd = CType(e.Row.FindControl("grdChildGridEdit"),
GridView)
MasterTableID = Convert.ToInt32(CType(e.Row.DataItem, _
DataRowView).Row.ItemArray(0).ToString())
intMAsterID1 = MasterTableID
If grd IsNot Nothing Then
grd.DataSourceID = ""
grd.DataSource = ChildDataSource
ChildDataSource.SelectParameters(_
"MasterTableID").DefaultValue = intMAsterID1
ChildDataSource.Select()
grd.DataBind()

To C#.
DataRowState objListItem = new DataRowState();
int intMAsterID1;
if (e.Row.RowType = DataControlRowType.DataRow)
{
GridView grd = new GridView();
if (objListItem = 5)
{
grd = (GridView)
(e.Row.FindControl("grdChildGridEdit"));
//Cant get this line. I havent used vb before.
//intMAsterID1 =
int.Parse(e.Row.DataItem).Row.ItemArray(0).ToString())
if (grd != null)
{
grd.DataSourceID = "";
grd.DataSource = ChildDataSource;
}
}
}

This should use ==.
//Cant get this line. I havent used vb before.
//intMAsterID1 =
int.Parse(e.Row.DataItem).Row.ItemArray(0).ToString())
Click to expand...

Should be ItemArray[0] (in C#, use square brackets for the indexer,
instead of parenthesis). Also note that you are missing an opening
parenthesis.
BTW, int.Parse is not always equivalent to Convert.Int32. If you want to
preserve the original semantics, use this:

MasterTableID =
Convert.ToInt32(((DataRowView)e.Row.DataItem).Row.ItemArray[0].ToString());

Don't create instances that you won't use.

DataControlRowState objListItem;

You missed a line:

objListItem = e.Row.RowState;
int intMAsterID1;
if (e.Row.RowType = DataControlRowType.DataRow)
Click to expand...

The operator == is used for comparison:

if (e.Row.RowType == DataControlRowType.DataRow)
{
GridView grd = new GridView();
Click to expand...

GridView grd;
if (objListItem = 5)
Click to expand...

if (objListItem == 5)
{
grd = (GridView)
(e.Row.FindControl("grdChildGridEdit"));
//Cant get this line. I havent used vb before.
//intMAsterID1 =
int.Parse(e.Row.DataItem).Row.ItemArray(0).ToString())
Click to expand...

The equivalent is this (but will eventually use Parse anyway):

intMAsterID1 =
Convert.ToInt32(((DataRowView)e.Row.DataItem).Row.ItemArray(0).ToString())

However, you should try to convert the value directly instead of
converting to a string and then parse the string.
if (grd != null)
{
grd.DataSourceID = "";
grd.DataSource = ChildDataSource;
Click to expand...

Missing:

ChildDataSource.SelectParameters("MasterTableID").DefaultValue =
intMAsterID1;
ChildDataSource.Select();
grd.DataBind();
 
DataControlRowState objListItem;
objListItem = e.Row.RowState;
int intMAsterID1 = 0;
if (e.Row.RowType == DataControlRowType.DataRow)
{
GridView grd = null;
if (objListItem == 5)
{
grd = (GridView)(e.Row.FindControl("grdChildGridEdit"));
MasterTableID =
Convert.ToInt32(((DataRowView)e.Row.DataItem).Row.ItemArray[0].ToString());
intMAsterID1 = MasterTableID;
if (grd != null)
{
grd.DataSourceID = "";
grd.DataSource = ChildDataSource;
ChildDataSource.SelectParameters("MasterTableID").DefaultValue =
intMAsterID1;
ChildDataSource.Select();
grd.DataBind();
}
}
}

The lazy way...
Drop it into an assembly.
Download .NET Reflector.
In Reflector go to View > Options
Set it to disassemble to C#
Find grdMaster_RowDataBound(...
Click Tools > Disassemble
