GridView

blurMember

I am using c#. i have a gridview and one of the column is Category. I have used the objectdatasource to bind the data. I want to count the number of "P" exist in that column and display it at the footer of the gridview. int presentCount = 0; protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { //if ( # = "P") presentCount++; } else if (e.Row.RowType == DataControlRowType.Footer) { e.Row.Cells[3].Text = presentCount.ToString(); } } What whould be the correct way. What syntax should be replaced by #? Is there any sample I can follow?

thanks in advance. Much appreciated.

Hi, Please check wether you can write e.Row["Category"] = "P" instead of # = "P". I think this will help !

thanks in advance. Much appreciated.

Hi, Sorry about that but i dont know about the GridView. You can use the cells collection of the row - r.Row.Cells(0) where the '0' is column number of your desired column. I am not sure about it but you can atleast try ! check this - http://msdn2.microsoft.com/en-us/library/system.web.ui.webcontrols.tablerow.cells.aspx[^]

Hi Blur Member .... u may use ," e.Row.Cells[index].Text " to get the value on that Particular Cell ( index th position, zero indexing) of the current row. Hope It works..

There was an error. Error 1 Cannot implicitly convert type 'string' to 'bool' C:\WebSites\Attendance\Admin\frm_Report.aspx.cs 322 17 C:\WebSites\Attendance\ protected void GridView4_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { if (e.Row.Cells[3].Text = "P") { presentCount++; } } else if (e.Row.RowType == DataControlRowType.Footer) { e.Row.Cells[3].Text = presentCount.ToString(); }

thanks for your help so far Jay

if (e.Row.Cells[3].Text == "P") put '==' operator for comparision

Basically I have a dropdownlist which filter adminNo and then display each record at the gridview. So user can see how many P exists in column Category for each adminNo. the result display at the footer is 0. i hope it is not due to me filtering records by dropdownlist.

jay thanks

Whether it works or not ? You need to declare the variable 'presentCount' as a 'static' variable inorder to retain its value during the Gridview is population.

I hope my declaration is correct. public static int presentCount = 0; But yet the footer still show 0. :((

JAY THANKS

Try out this !.............

int presentCount = 0;
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
YourType obj = e.Row.DataItem as YourType;
if ( obj.Property = "P")
presentCount++;
}
else if (e.Row.RowType == DataControlRowType.Footer)
{
e.Row.Cells[3].Text = presentCount.ToString();
}
}

i am having doubt the data type need to be used. What is the best solution? My Category value is a char data type from the database. :^)

thanks in advance. Much appreciated.

Believe me it works fine... I think , ur data "P" came from database. It may have some white spaces. use Trim() method to remove that, then the string comparision works properly. Hope it help u... static int count = 0; protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { string tmp=(e.Row.Cells[3].Text).Trim(); if (tmp == "P") { count += 1; } } if (e.Row.RowType == DataControlRowType.Footer) { e.Row.Cells[3].Text = count.ToString(); } } -- modified at 6:27 Thursday 17th August, 2006

When the user click from the ListBox to view each adminNo, the Show Footer manage to calculate the number of P exist in the gridview. But when the user click another adminNo, the Show Footer number was accumulated with the previous Show Footer. Example: when the user click for the first time Show Footer: 18 second output when user click for the second time, the number of P exist in the gridview is suppose to be 10, but show 38 instead Show Footer: 38

thanks in advance. Much appreciated.

i think the static variable 'showCount' keeps its old value. So you may declare it properly , in such a way that when u click a item from ur ListBox , the variable is set to zero. hope it helps u

X| My flu and cough is really bad, i can't even think. :laugh: protected void ListBox1_SelectedIndexChanged(object sender, EventArgs e) { count = 0; } I did this to save my trouble. Hope no more problem.
