Question

In my gridview I put this code to get the click in my gridview row.

$('#grdImoveis tr').click(function () {
        openPopup('../Financeiro/DetalheImovelProposta.aspx', 'Detalhes', 'toolbar=yes,directories=no,status=yes,menubar=yes, scrollbars=yes,resizable=yes', '850', '600', 'true');
    });

In my gridview I have 5 columns. How can I get the value of the first column in the clicked row and pass via querystring ?

I think in some solution like this

$('#grdImoveis tr').click(function () {
        // Get the value of a specific column of my clicked row.
        //var imovel = $('# ???)
        openPopup('../Financeiro/DetalheImovelProposta.aspx?Imovel_id=' + imovel, 'Detalhes', 'toolbar=yes,directories=no,status=yes,menubar=yes, scrollbars=yes,resizable=yes', '850', '600', 'true');
    });

Skip the javascript stuff and do it server side instead. Add the following code in the RowDataBound event of the GridView

protected void grdImovei_RowDataBound(Object sender, GridViewRowEventArgs e)
{
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
       var url = "../Financeiro/DetalheImovelProposta.aspx?Imovel_Id=" +
                 ((SomeType)r.Row.DataItem).Imovel_id.ToString();

       e.Row.Attributes.Add("onclick", "openPopup('" + url + "'," +
           @"'Detalhes', 
           'toolbar=yes,directories=no,status=yes,menubar=yes,
           scrollbars=yes,resizable=yes', '850', '600', 'true');");
    }
}

Where SomeType is the type of the items in your datasource.

Edit
For SqlDataSource try this:

var url = "../Financeiro/DetalheImovelProposta.aspx?Imovel_Id=" +
                     ((DataRowView)r.Row.DataItem)["Imovel_id"].ToString();
