I have a parent grid which calls two child grids. But for some unknown reason they are getting fired twice. I cant't really seem to figure out the problem with this code. Can anyone guide me?
Backend Code (C#):
protected void grdGrpPrntRpt_RowDataBound(object sender,
GridViewRowEventArgs e)
{
try
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
TextBox litGrp = (TextBox)e.Row.FindControl("litGrp");
litGrp.Text =
DataBinder.Eval(e.Row.DataItem, "GroupName").ToString();
ViewState["GroupName"] = litGrp.Text;
DataSet ds = (DataSet)ViewState["ds"];
DataView dv = ds.Tables[3].DefaultView;
dv.RowFilter = "GroupName='" + litGrp.Text + "'";
DataTable dt = dv.ToTable();
GridView gvinner = (GridView)e.Row.FindControl("grdInnerMain");
gvinner.DataSource = dt;
gvinner.DataBind();
}
}
catch (Exception Ex)
{
//report error
}
}
protected void grdInnerMain_RowDataBound(object sender,
GridViewRowEventArgs e)
{
try
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
TextBox litUsr = (TextBox)e.Row.FindControl("litUsr");
litUsr.Text =
DataBinder.Eval(e.Row.DataItem, "FirstName").ToString();
// string username=
DataSet ds = (DataSet)ViewState["ds"];
DataView dv = ds.Tables[3].DefaultView;
dv.RowFilter = "userName='" +
DataBinder.Eval(e.Row.DataItem, "UserName").ToString().Replace("'",
"''") + "' and GroupName='" + ViewState["GroupName"].ToString()
+ "'";
DataTable dt = dv.ToTable();
totalPages = 0;
totalCost = 0;
GridView gvinner2 = (GridView)e.Row.FindControl("innerGrid");
gvinner2.DataSource = dt;
gvinner2.DataBind();
}
}
catch (Exception Ex)
{
//report error
}
}
protected void innerGrid_RowDataBound(object sender,
GridViewRowEventArgs e)
{
try
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
DataView dv =
((DataSet)ViewState["dspaper"]).Tables[0].DefaultView;
dv.RowFilter = "paperid=" +
Convert.ToInt32(DataBinder.Eval(e.Row.DataItem,
"paperid").ToString());
DataTable dt = dv.ToTable();
e.Row.Cells[0].Text = dt.Rows[0]["PaperName"].ToString();
// e.Row.Cells[2].Text = DataBinder.Eval(e.Row.DataItem,
"TotalPagesPrinted").ToString() == "0" ? DataBinder.Eval(e.Row.DataItem,
"TotalPagesSent").ToString() : DataBinder.Eval(e.Row.DataItem,
"TotalPagesPrinted").ToString();
e.Row.Cells[2].Text = DataBinder.Eval(e.Row.DataItem,
"TotalPage").ToString() == "0" ? DataBinder.Eval(e.Row.DataItem,
"Pages_Sent").ToString() : DataBinder.Eval(e.Row.DataItem,
"TotalPage").ToString();
// e.Row.Cells[3].Text =
Convert.ToDouble(e.Row.Cells[3].Text.ToString()).ToString("0.00");
totalPages += Convert.ToInt32(e.Row.Cells[2].Text.ToString());
totalCost += Convert.ToDouble(e.Row.Cells[3].Text.ToString());
e.Row.Cells[1].Text = DataBinder.Eval(e.Row.DataItem,
"Color").ToString() == "0" ? "B & W" : "Color";
}
if (e.Row.RowType == DataControlRowType.Footer)
{
e.Row.Cells[2].Text = totalPages.ToString();
e.Row.Cells[3].Text = totalCost.ToString("0.00");
}
if (e.Row.RowType == DataControlRowType.Header)
{
e.Row.Cells[0].Text =
CResourcesManager.GetString("grdHeaderMediaReport");
e.Row.Cells[1].Text =
CResourcesManager.GetString("grdHeaderColorReport");
e.Row.Cells[2].Text =
CResourcesManager.GetString("grdHeaderPagesReport"); ;
e.Row.Cells[3].Text =
CResourcesManager.GetString("grdHeaderTotalCostReport");
}
}
catch
{ }
}

Extra Information
For some reason the event grdGrpPrntRpt_RowDataBound is called as many times as there is data in the next grid. It should terminate as soon as the entire data in the next two grids gets bound but it again calls it and repeats the entire process again.

It may be possible due to AutoEventWireUp , It may be true in your code.
If it is, Please make it false. Thanks
